Five CubeSats Successfully Deployed from “Kibo” Module on ISS

On December 9th, five CubeSats were successfully deployed from the Japanese Experiment Module “Kibo” aboard the International Space Station (ISS). The deployment was part of JAXA’s J-SSOD#30 mission and included DENDEN-01, LignoSat, ONGLAISAT, YODAKA and YOMOGI satellites. Two of these satellites, LignoSat and YOMOGI, have received previous IARU coordination to operate over amateur radio frequencies.

LignoSat was developed by Kyoto University and Sumitomo Forestry Co., Ltd. This CubeSat tests the use of wooden materials in space by measuring strain, temperature, and geomagnetism, along with detecting single event upsets (SEU). Amatuer radio satellite enthusiasts were ready to decode telemetry from the satellite this week, but unfortunately there has been no reported reception of either CW or AX.25 packets on the satellite’s coordinated frequency of 435.820 MHz.

DENDEN-01 was developed by Kansai University and partner institutions. Its mission includes testing advanced nanosatellite technologies, such as temperature-stabilizing devices, thin solar modules, and compact S-band communication systems. The satellite also supports educational activities and data analysis using a compact hyperspectral camera.

ONGLAISAT is a 6U CubeSat co-developed by the Taiwan Space Agency, the University of Tokyo, and ArkEdge Space Inc. It features a telescope for high-resolution Earth imaging using Time Delay Integration (TDI) technology. This mission aims to produce clear and high signal-to-noise ratio images for Earth observation.

YOMOGI was developed by the Chiba Institute of Technology. Its mission combines environmental monitoring and engineering education. The satellite observes red tide in Tokyo Bay, monitors water pollution in Uganda, and uses APRS to send sensor data to ground stations. Many 4800 baud GMSK telemetry packets have been received and decoded over the last few days indicating that the satellite is functioning well. More information can be found on SatNOGS regarding recent observations: https://db.satnogs.org/satellite/HHVN-9456-4962-8588-2802#data

YODAKA was developed by ArkEdge Space Inc. and other collaborators. It features a store-and-forward communication mission, collecting and retransmitting text messages from users on Earth, as well as a camera mission to capture Earth imagery. These activities support educational programs at Iwate Prefectural Hanamaki Kita High School and rural revitalization efforts in Hanamaki City.

The deployment highlights collaboration between JAXA, Space BD Inc., Mitsui Bussan Aerospace Co., Ltd., and the J-CUBE program, which fosters academic and commercial utilization of CubeSats. Amateur radio operators and educational institutions are actively participating in tracking and analyzing data from these satellites.

ESA’s Proba-3 Satellites Launch to Create Artificial Solar Eclipses

Two European Space Agency (ESA) satellites launched aboard an Indian rocket on December 5th, beginning a mission to study the Sun’s corona and demonstrate new spaceflight technologies. Called the Proba-3 mission, the two spacecraft will conduct formation flying and create artificial solar eclipses to capture images of the Sun’s outer atmosphere, which is usually hidden by its brightness.

The satellites launched aboard India’s Polar Satellite Launch Vehicle (PSLV) at 5:34 am EST (10:34 UTC) and were placed into an elliptical orbit with a low point of 356 miles (573 kilometers) and a high point of 37,632 miles (60,563 kilometers). Early next year, the Coronagraph satellite, carrying instruments to image the Sun, and the Occulter satellite, equipped with navigation sensors and thrusters, will separate to begin their experiments. The Occulter will position a disk to block the Sun’s surface, casting a shadow on the Coronagraph satellite.

This arrangement allows scientists to create artificial eclipses, blocking sunlight to reveal the solar corona. Natural solar eclipses offer only brief observation windows, and traditional coronagraphs on single spacecraft face challenges like diffraction. Proba-3 addresses these limitations by keeping the two satellites 150 meters apart, enabling clearer imaging of the Sun’s outer atmosphere.

Proba-3 uses advanced navigation technology, including inter-satellite radio links, cameras, and a laser-ranging system. This system maintains millimeter-scale precision between the satellites, allowing them to create artificial eclipses lasting up to six hours. The mission aims to conduct at least 1,000 hours of such observations during its two-year operational phase.

The mission’s scientific goal is to observe a part of the corona that existing instruments cannot study. This region is critical for understanding solar phenomena such as coronal mass ejections and the acceleration of the solar wind, which affect space weather and Earth. The mission will also capture high-frequency images to study plasma waves and jets that may heat the corona and drive the solar wind.

Proba-3 also serves as a test of formation-flying technology. ESA officials hope the techniques demonstrated will be used in future missions, such as Mars Sample Return or space debris removal. “Proba-3 is an important step toward more complex space operations,” said Josef Aschbacher, ESA’s director general. “This mission shows how smaller spacecraft can work together to achieve goals that were not possible before.”

Satellite Shorts From All Over

+ NASA has announced delays to its Artemis moon program, pushing Artemis II, a crewed mission around the moon, to April 2026, with the Artemis III lunar landing planned for mid-2027. NASA Administrator Bill Nelson emphasized that this timeline keeps the U.S. ahead of China’s goal to land on the moon by 2030, highlighting the competitive nature of the space race. The delays follow concerns about the Orion capsule’s heat shield, which cracked during reentry after the uncrewed Artemis I test mission in 2022; Artemis II will proceed with adjustments to the capsule’s trajectory, while future missions will feature an upgraded heat shield. Artemis, initiated under former President Trump’s administration, aims not only to return astronauts to the moon but also to establish lunar bases as a stepping stone for Mars exploration, despite rising costs and development delays. The program’s reliance on SpaceX’s Starship for lunar landings has raised questions about its cost-effectiveness, especially under the incoming Trump administration. Nelson expressed optimism about Artemis’s continuity under NASA’s next administrator, Jared Isaacman, amid ongoing bipartisan and international support for lunar exploration.

+ Less than a week after its December 5th launch aboard a Vega-C rocket, the Sentinel-1C satellite delivered its first radar images, showcasing its advanced capabilities in environmental monitoring. Equipped with a cutting-edge C-band synthetic aperture radar (SAR), Sentinel-1C operates in all weather and lighting conditions, supporting critical applications like climate change research, disaster response, and environmental management. Early images captured regions such as Svalbard, Norway, highlighting its ability to monitor Arctic ice coverage, the Netherlands, showcasing intricate details for agriculture and water management, and Brussels, Belgium, revealing dense urban landscapes with historical ties to the Sentinel program. These high-resolution radar images, processed flawlessly by the Sentinel-1 Ground Segment, underline the satellite’s potential for actionable insights into soil moisture, urban planning, and polar ecosystems. Sentinel-1C continues the legacy of its predecessors while expanding its role in marine surveillance, ground deformation observation, and global humanitarian aid. Freely available via the Copernicus Data Space Ecosystem, Sentinel-1C’s data ensures robust support for diverse Copernicus services and scientific applications worldwide.

+ NASA recently awarded SpaceX a $256.6 million contract to launch Dragonfly, a rotorcraft designed to explore Titan, Saturn’s largest moon, using a nuclear-powered radioisotope thermoelectric generator (RTG). This marks a milestone for SpaceX, as it will be the company’s first time launching a nuclear-powered payload, a domain previously dominated by United Launch Alliance (ULA). The RTG will generate electricity from plutonium-238, chosen because Titan’s dim and cloudy atmosphere precludes the use of solar power. Dragonfly will explore Titan’s surface by hopping between locations using its eight rotors, investigating organic molecules essential to understanding the building blocks of life. Originally set for a 2026 launch, delays due to redesigns, COVID-19 impacts, and supply chain issues have pushed the timeline to July 2028, with costs escalating to $3.35 billion. This mission, one of NASA’s most ambitious robotic endeavors, underscores the transition to new-generation rockets for launching nuclear payloads, with SpaceX’s Falcon Heavy beating ULA’s Vulcan rocket in competitive bidding for this historic mission. (ANS thanks SpaceNews for the above information)

+ The USC Rocket Propulsion Lab (USCRPL) at the University of Southern California has shattered the international altitude record for amateur rocketry with their Aftershock II rocket, reaching an unprecedented 470,000 feet. This achievement surpasses the previous 20-year record of 380,000 feet set by the Civilian Space Exploration Team in 2004, establishing Aftershock II as the first civilian-built rocket to achieve this altitude. Equipped with the most powerful solid-propellant motor ever fired by students and enhanced thermal protection systems, the rocket endured hypersonic speeds with innovative features like titanium-coated fins and a custom paint system. The launch on October 20th in Nevada’s Black Rock Desert also demonstrated advanced avionics and live data integration, enabling precise tracking and recovery. Building on their milestone 2019 launch of Traveler IV, the first student-designed rocket to cross the Kármán line, USCRPL continues to push the boundaries of amateur rocketry with cutting-edge engineering and teamwork. This remarkable achievement highlights the group’s role as a training ground for future leaders in the space industry, inspiring innovation and excellence among aspiring astronautical engineers.

LignoSat ISS Deployment Information

LignoSat is a 1U-sized CubeSat whose outside structure is mainly composed of wood. In the development of wooden artificial satellites, we can produce wooden structures by using a familiar material “wood” and the usual manufacturing techniques. This will provide more people with the opportunity to develop amateur satellites at a lower cost.

This satellite performs the following missions:

1. Amateur Radio Mission LignoSat will extract call signs of the amateur radio stations from the FM packet data signals uplinked, and respond to them by using the CW downlink and their call signs to send “thank you” messages. This shows the success of the interactive satellite communication using only UHF frequencies.

2. Educational mission Another LignoSat mission is to educate students to learn about the characteristics of the satellite by acquiring its HK data such as the internal temperature, the strain of the wooden structure, and the Earth’s magnetic field and calculating the rotational direction and rate of the satellite as well as observing the effect of the space environment on the wooden structure of LignoSat.

Date and time of deployment: December 9, 2024, 20:30 JST/11:30 UTC +-90min

Downlink frequency of CW beacon: 435.82MHz +-Doppler

Please track the satellite using the orbital elements (TLE) of the ISS for a while after deployment. As time passes, it will gradually fly ahead of the ISS.

The first path in Japan is expected to be around 06:30 JST on December 10th

The antenna is scheduled to be deployed 30 minutes after deployment, so if the deployment is early, it may be possible to receive the satellite during the first pass in eastern North America (around 12:20 UTC).

If the deployment is late, it may be possible to receive the satellite during the first pass in the EU (around 12:37 UTC).

A release event is scheduled to take place on the JAXA YouTube channel.

Please send your reception reports to [email protected] thank you.

HADES-ICM Offering FM Transponder to Launch Q1 2025

The HADES-ICM 1.5p PocketQube recently underwent testing at UPM/IDR University in Madrid. It will offer the amateur radio community a VHF/UHF FM voice repeater as the one of SO-121 (HADES-D) but more powerful. It is scheduled to be launched in Q1 2025 aboard the SpaceX Transporter-13 mission.

HADES-ICM 1.5 PQ satellite main mission is to act as a FM voice repeater. It can also repeat FSK derived modes like FT-4 and FT-8. As there is a small empty space available, it will be used to carry an experiment by Smart IR/Graphene Engineering Innovation Centre, GEIC University of Manchester (UK) consisting in a very low power active radiator to be tested on space conditions. The data for this experiment will be transmitted in a specific data packet in the telemetry. This experiment is the same as the one in HADES-R. This experiment will be delivered to AMSAT EA for integration and will be operated by AMSAT-EA, being all its data public and open. Engineering and manufacturing support for this mission is carried out with the help of private sector companies and universities, but AMSAT-EA will be the only operating organization. icMercury is a company also supporting the mission. It will develop ground tracking software for the satellite. Telemetry will send some FSK English formatted text messages, part of a history, to be collected as a challenge. HADES-ICM will offer licensed radio-amateur around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. FSK derived transmissions and modes like FT-4 and FT-8 are also supported. As an improvement from previous missions, maximum power is now 0.25W when battery is charged (the amplifier uses battery energy), allowing easier QSOs with handheld antennas like Arrow or Elk and less sensitive receivers. The satellite will also transmit telemetry with its status and CW messages. This all will be achieved by implementing a SDR based repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a subtone. As payload, the satellite will carry an experiment by Smart IR/Graphene Engineering Innovation Centre, GEIC University of Manchester (UK) consisting in a very low power active radiator to be tested on space conditions. This experiment is the same as the one in HADES-R satellite with updates and improvements. Also, as a challenge made with icMercury, telemetry will send FSK English formatted text messages, part of a history, to be collected. Launch is expected for February 2025 in SpaceX Transporter-13 mission managed by the space broker Alba Orbital / D-Orbit. The main mission for the satellite is to act as a FM voice repeater although due to its SDR nature it can repeat data too. Users will have the capability of making voice contacts and use FSK derived modes like FT-4 and FT-8. This satellite is based on the hardware of HADES-D (SO-121, currently being used by HAMs worldwide for voice contacts) and the next to launch HADES-R. FM satellites are very demanded and appreciated by the HAM community because they are easy to use, they don’t require of expensive transceivers and allow continental and even transatlantic contacts in some conditions. With this satellite we also put into use the amateur VHF and UHF satellite sub-bands helping to secure them for the community in the future.

Gaston Bertels, ON4WF, SK

This past week, Frank Bauer KA3HDO ARISS-USA Executive Director and ARISS International Chair passed this along to the ARISS volunteers:

It is with great sorrow that we announce the passing of Gaston Bertels, ON4WF (SK).  Gaston died today, December 3, 2024, from cancer.  He was 97.

Gaston was recently given the title “Elder Statesman” by the ARISS International team. This honor was given because of his monumental role in the formation and operation of the ARISS team. He wrote our ARISS Terms of Reference and participated in numerous discussions, over the years, on how to run a cohesive, results-oriented international team. His in-depth knowledge of amateur radio rules and regulations, particularly his knowledge of licensing and 3rd party traffic, enabled ARISS to develop an operations plan that could support human spaceflight amateur radio operations across the world. His knowledge of radio telecommunications was respected in Europe and elsewhere, allowing him to give presentations on amateur radio in space to members of the European Parliament. His personality radiated an inviting aura to all. He has been a friend, a leader, and an inspiration to all of us.

Gaston began his journey in human spaceflight amateur radio by guiding a group of engaging students in a radio contact at a Belgian Space Camp during the 1992 STS-45 Space Shuttle mission. This contact was with Belgium’s first Astronaut, Dirk Frimout ON1AFD. Gaston coordinated the radio contact preparations and operated the radio station during the contact. Gaston was instrumental in convincing ESA to install L/S band antennas on the Columbus module, prior to launch, to support future operations in Columbus. He worked with Professor Pawel Kabacik from the Wroclaw University to design, build and certify the antennas and led a fundraising campaign to pay for the development, test and certification. With HamTV as the first hardware “customer” of these antennas, Gaston led the HTT, the HamTV Technical Team meetings to prepare the HamTV ground stations for operations and to coordinate the on-board HamTV operations. The L/S antennas have also been employed for two flight experiments:  MarconISSta with TU Berlin and the upcoming NAVCOM experiment for ASI/Qascom.

Gaston will be sorely missed.  But the light of his legacy shines in all of us that he has touched—inside and outside of ARISS.

Ad Astra Gaston!  (To the Stars, Gaston!)

AMSAT OSCAR-7 50th Anniversary: CodeStore Breaking New Ground


There has always been a fascination among radio amateurs in digital modes of communications. In thinking about where this spacecraft sits in electronic history, it is all too easy to forget that it was designed at least three years before the appearance of the first 8-bit microprocessor. The notion of packet communications was still nearly 10 years into the future. The team wanted to demonstrate that they could store data at-will on a spacecraft in transit across the sky and then download it at another location. They wanted to demonstrate non-real-time digital communications to themselves and to the world.

Jan King, W3GEY, AMSAT OSCAR-7 Project Manager explains, “Thinking in retrospect, that experiment wasn’t the best it could have been. However, it was simple and it proved our resolve. The entry in 1972 on AO-6 and, then again, in 1974 on-board AO-7 was a demonstration experiment we called CodeStore. And, it did lead to far more ambitious packetized, store-and-forward data satellites in our future.

“It probably wasn’t the best choice at the time, but we chose the command frequency for the uplink. This meant we didn’t have to implement yet another receiver. However, this made the experiment far less accessible to hams than it could have. AMSAT did not want to share the knowledge of the command frequency and codes with anyone who didn’t have a need to know them. Thus, CodeStore was not an experiment that was shared with everyone as were the communications transponders. It could realistically only be used by authorized command stations. We had hoped for a universal store-and-forward demonstration, but what was in fact created was a broadcast tool and in that regard CodeStore was very successful.”

CodeStore was the brainchild of and was designed and fabricated by John Goode, W5CAY. In one small module, he housed an AFSK decoding system, which allowed uplink data to be clocked into a “long” shift register containing 896 bits. This was done with the memory IC’s of the day. What one could manage then was 14 IC’s each containing 64 bits of serial data storage. The contents of the shift register was sequentially downlinked first-in-first-out (FIFO) to the selected beacon when CodeStore was commanded to the RUN mode.

This number of bits is divisible by 8 so one might have expected that a downlinked message of 112 8-bit words. No, this was 1974 so Morse Code messages were downlinked. The idea was more individuals can copy a broadcast message if they don’t need specialized decoding equipment. King adds, “No one can deny that we could have made a better go of it if the notion of a remote terminal digital communications goal had remained pure. It did not.”

“Ultimately, its highest value was discovered to be to store the spacecraft’s NORAD TLEs as well as any critical AO-7 operating schedule modifications, which might be of importance to the users. CodeStore was already available for use on AO-6. So, users were already expecting this feature, which appeared regularly on the beacons.”

While CodeStore was used on both AO-6 and AO-7 to demonstrate non-real-time communications via satellite, it was never used by independent remotely located stations to demonstrate two-way communications in that way. The memory facilities required on-board and the lack of any firmware that even approached the capabilities of a file handling system did not exist in 1972-74. That would have to wait for another day when, once again, four AMSAT spacecraft in a small constellation would demonstrate a proper store-and-forward packet handling system. That was to occur in 1990.

CodeStore went into service as a broadcast device allowing users to receive, in Morse Code, the latest, (then) NORAD TLEs. CodeStore was a complete success. It saved command stations a tremendous amount of work, avoiding the need for a global network of operators who would otherwise be needed to relay the same data.

Japan Launches World’s First Wooden Satellite to Test Timber in Space

Japanese researchers launched the world’s first wooden satellite, LignoSat, into space, marking an ambitious step toward exploring the viability of timber for lunar and Martian construction. This pioneering satellite, developed collaboratively by Kyoto University and Sumitomo Forestry, was sent to the International Space Station aboard a SpaceX mission from NASA’s Kennedy Space Center on November 4, 2024. Once at the ISS, LignoSat will be released into orbit approximately 400 kilometers (250 miles) above Earth.

LignoSat, a 1U-sized CubeSat, carries an Amateur Radio mission that will extract callsigns from the FM packet data signals uplinked, and respond to them by using the CW downlink with their call signs.

An educational mission is to educate students to learn about the characteristics of the satellite by acquiring its housekeeping data such as the internal temperature, the strain of the wooden structure, and the Earth’s magnetic field and calculating the rotational direction and rate of the satellite as well as observing the effect of the space environment on the wooden structure.

The satellite, whose name derives from the Latin word for “wood,” is a compact, palm-sized structure. LignoSat’s mission is to demonstrate the potential of wood as a sustainable and durable material for space exploration. Takao Doi, a former astronaut and a current researcher at Kyoto University, expressed that using timber could pave the way for constructing habitats that support human life and work in space indefinitely. “With timber, a material we can produce by ourselves, we will be able to build houses, live, and work in space forever,” Doi said.

Doi’s team is working under a 50-year vision of building timber structures on the Moon and Mars, planting the seeds for future space-based infrastructure. The researchers opted for Honoki, a type of magnolia tree native to Japan traditionally used for sword sheaths, after conducting a 10-month experiment on the ISS. Honoki proved its resilience, leading to its selection as the core material for LignoSat. The satellite was constructed using a traditional Japanese craft technique without screws or glue, showcasing innovation steeped in heritage.

One of LignoSat’s key roles in its six-month orbit will be to measure the endurance of wood against extreme space temperatures, which oscillate from -100 to 100 degrees Celsius (-148 to 212 degrees Fahrenheit) every 45 minutes as the satellite shifts from sunlight to darkness. The onboard sensors will also monitor how well wood mitigates space radiation’s impact on semiconductors, information that could be pivotal for designing data centers and other space-based structures. Kenji Kariya of Sumitomo Forestry emphasized the cutting-edge nature of this research, noting that despite appearing old-fashioned, wood could be integral to future space technology.

The environmental benefits of using wood in space are significant. Unlike conventional metal satellites that produce polluting aluminum oxide particles upon re-entry, wooden satellites would disintegrate more cleanly in Earth’s atmosphere. “A wooden satellite burns up with much less pollution compared to metal ones,” Doi stated. This feature could be an advantage as the space industry grapples with sustainability and the proliferation of space debris.

The team behind LignoSat is optimistic that their experiment could spur wider adoption of timber in space exploration. Doi even hinted at the potential for future partnerships, saying, “If we can prove our first wooden satellite works, we want to pitch it to Elon Musk’s SpaceX.” The successful deployment of LignoSat could mark the beginning of a new era where traditional materials meet advanced space technology, reinvigorating the timber industry and pushing the boundaries of sustainable innovation in space exploration.

A downlink on 435.820 MHz has been coordinated for CW, 4k8 GMSK AX25 telemetry and FM. More info at https://space.innovationkyoto.org/amateur-radio-operators/

Open-Weather APT: Updates to the Web Based NOAA APT Image Decoder

Dr. Sasha Engelmann and Sophie Dyer, the team behind the Open-Weather project have recently announced the launch of their new version of open-weather app, a web-based NOAA APT image decoder. The web-based program accepts a WAV file containing a NOAA satellite APT recording, demodulates and decodes it, and displays the resulting weather satellite image.

Sasha writes, “…Open-weather apt is the only public, maintained, browser-based decoder for Automatic Picture Transmissions (APT) from satellites NOAA-19, NOAA-18 and NOAA-15. It was developed to improve access to satellite signal decoding for all practitioners.

“We are excited to share a new and improved version available here! The new version includes the following updates and additional features:

Improved accuracy in decoding and finding sync positions (locates more sync positions than other comparable decoders)
Upload a WAV file of any sample rate (no more re-sampling with Audacity!)
Option to see the ‘raw’ image without syncing, and to ‘Find the Syncs’
Option to Rotate 180 degrees, often useful for viewing images from nighttime passes
Go deeper in your analysis: explore Signal Value and Image Value Histograms
Upload directly from open-weather apt to the Public Archive

“Open-weather apt is co-developed by open-weather with Rectangle (Lizzie Malcolm and Dan Powers), Bill Liles (NQ6Z) and Grayson Earle.”

Satellite Shorts From All Over

  • NASA has confirmed that one of its greatest ever missions, Voyager 1, is back in business with communications restored following an incident in October that had led to the veteran spacefarer losing its voice. When engineers commanded Voyager 1 to switch on one of its heaters to give the instruments a gentle thermal massage, a safety feature was tripped because of low power levels. It automatically switched off non-essential systems. The fault protection system took it upon itself to switch off the main X-band transmitter and activate the lower-power S-band transmitter instead. Because of the great distance between Voyager 1 and Earth, however, transmissions on the S-band antenna could not be heard by NASA’s Deep Space Network, meaning that Voyager 1 had effectively fallen silent. NASA engineers were able to resolve the problem early in November, and X-band communication resumed on Nov. 18, with the spacecraft once again returning data from its four remaining instruments.

AMSAT OSCAR-7 50th Anniversary — The Space Age, Morse Code and STEM Innovation

At first glance, there is something about Morse Code and the space age that don’t go together. But, think about Morse in its simple beauty.

In addition to building a few spacecraft and pursuing a global amateur radio allocation for satellites at the International Telecommunications Union World Radio Conference, AMSAT was also busy developing an educational curriculum. Before STEM (Science, Technology, Engineering and Mathematics) was even a concept, AMSAT thought it would be quite exciting to allow grade-school to high-school students the opportunity to understand the basics of a spacecraft — not by reading about it in a book, rather by using a real spacecraft, in class.

One of AMSAT’s members, Dr. Martin Davidoff, K2UBC, decided to write a curriculum at the secondary education level and received a grant from the Department of Energy to write it. The Satellite Experimenters Handbook was distributed by the American Radio Relay League (ARRL) and AMSAT to anyone who might want to teach others about spacecraft technology. The book especially targeted secondary school educators. Key among the concepts was the idea of giving a teacher, who may or may not be a radio amateur, the information necessary to assemble a receiving system, which could act as a student demonstration tool in school. This receiver and antenna would allow a class to “receive and decode” telemetry. This process, then, required the students to think through some orbital mechanics, the technology of antennas and receivers, and finally, the principles of demodulation and decoding.

This is where Morse came in. For just the numbers, 0-9, in Morse can be learned in 10 minutes by just about anyone. And, so it is a perfect tool for any eighth grader!

The Morse Code Telemetry Encoder System (TLM) was designed and fabricated by John Goode, W5CAY. This unit was built in one of the small modules that comprised the AO-7 spaceframe. This little box used fixed logic comprised of 34 IC’s and one op-amp for the A/D converter. Using CMOS components was amazingly efficient; it required 2 mA of current at 10V DC from the power bus – a whopping 20 mW!

This TLM encoder had 24 analog input channels that were organized in 4 columns and 6 rows. They were divided, basically, into current, voltage and temperature channels. All were scaled to a 1.0 V full- scale input to the A/D converter. The encoder produced decimal values and was organized into two Morse characters between 0 and 99. The first number of each word is a digit giving the row number of the datum. This reduces the ambiguity of where in the frame the encoder was; in case the student got a bit lost.

AMSAT’s commitment to STEM education continues today with its CubeSat Simulator program and its developing Youth Initiative – all fueled by a fifty-year-old satellite that is still in operation today.

ASRTU-1 Designated ASRTU-OSCAR 123

At the request of Harbin Institute of Technology and Amur State University, AMSAT has designated ASRTU-1 as ASRTU-OSCAR 123 (AO-123).


Illustration of AO-123 [Credit: nanosats.eu]

ASRTU-1 was launched on November 4, 2024 at 23:18 UTC, on a Soyuz launch vehicle from Vostochny Cosmodrome, Russia. Built and operated by Harbin Institute of Technology and Amur State University, the satellite carries a V/U repeater, UHF SSDV digital image transmitter, and a 10.5 GHz QPSK image transmitter. All of these payloads have been successfully tested, and the repeater has been operational for QSOs.

The satellite contains an FM transponder, which is currently operational, with an uplink of 145.850 MHz (67 Hz CTCSS tone required) and a downlink of 435.400 MHz. After the repeater detects the end of uplink, it will wait for 0.5s. If no new uplink in 0.5s, telemetry will be sent. So make fast QSOs so the telemetry is less like to interrupt you.

The satellite also contains two cameras with an SSDV downlink for low resolution images on 436.210 MHz, and a high speed downlink on 10.460 GHz for high resolution images.

Windows software for decoding telemetry is available at https://drive.google.com/file/d/1W8nm-P0_h0J1Bd1eif74mLo-EuRdWcjH

New Chinese Satellite Completes Frequency Coordination

The satellite frequency coordination committee of the International Amateur Radio Union (IARU) on November 15 completed approval of frequency requests from the Chinese Amateur Satellite Group (CAMSAT) for a new amateur satellite to be launched next year.

CAS-11, a 6U CubeSat will include:

  • HF/UHF – H/U Mode Linear Transponder, with a bandwidth of 15kHz downlink centered at 435.505 MHz, EIRP 24 dBm
    Uplink 21.320 MHz +/- 7.5 kHz.
  • VHF/UHF – V/U Mode Linear Transponder, with a bandwidth of 30kHz downlink centered at 435.540 MHz, EIRP 24 dBm.
    Uplink 145.860 MHz +/- 15 kHz.
  • VHF/UHF – V/U Mode FM Transponder, downlink at 435.600 MHz, EIRP 24 dBm
    Uplink at 145.925 MHz
  • VHF/UHF – V/U Mode digital store-and-forward Transponder, downlink at 435.700 MHz, EIRP 24 dBm
    Uplink at 145.895 MHz
  • UHF – CW Telemetry Beacon and
  • UHF telemetry beacon using AX.25 4.8k/9.6kbps GMSK at 435.570 MHz, EIRP 23 dBm.

The above transponders and beacon will work 24/7 when the satellite power supply is sufficient. Amateur radio enthusiasts around the world can use it for two-way radio relay communication, data storage and forwarding communication, and receive satellite CW beacons.

The CAS-11 satellite will also be equipped with a 2.4 GHz multi-mode amateur radio satellite beacon transmitter, which is designed and built by university students, high school students and primary school students from Beijing Donggaodi Science and Technology Museum and Beijing University of Posts and Telecommunications under the guidance of CAMSAT. This is an unprecedented satellite project in China. It has brought opportunities for learning and practicing amateur radio and amateur satellites to students of all grades from elementary school to university, and promoted the application of amateur radio in space. This 2.4 GHz experimental beacon transmitter can switch to transmit five different modes of radio signals, and it will work continuously when the satellite is fully powered.

This project aims to cultivate students’ knowledge, skills and interests in amateur radio satellites. All transmission modes operate at 2.4 GHz, and the working modes are converted by the on-board computer program and ground remote control commands. It can work in the following modes: CW Telemetry Beacon, FT8 Telemetry Beacon, PPM Telemetry Beacon, or USB/SSTV Robot36, PD120 1. This beacon will transmit at 2405.500 MHz, EIRP 27 dBm.

CAS-11 carries three cameras, and the photos it takes are stored in the flash memory on the satellite. The builders have designed a simple remote control system based on DTMF commands. Amateur radio enthusiasts around the world can send DTMF commands to download the photo catalog and all photos taken by all cameras.

Air Leak on ISS Russian Module Is Getting Worse

For the past five years, air has been escaping through a Russian section of the International Space Station (ISS) at an increasing rate. NASA and its Russian counterpart, Roscosmos, are still in disagreement over the root cause of the leak, as well as the severity of the consequences.

The leak was first discovered in 2019 in the vestibule (named PrK) that connects a docking port to the Russian Zvezda module, which Roscosmos had launched to low Earth orbit in July 2000. Earlier this year, NASA elevated the leak to the highest level of risk as the rate of air escaping from the module had doubled from one pound of air per day to a little over two pounds.

“While the Russian team continues to search for and seal the leaks, it does not believe catastrophic disintegration of the PrK is realistic,” Bob Cabana, a former NASA astronaut who now chairs the ISS Advisory Committee, said during a meeting on Wednesday, SpaceNews reported. “NASA has expressed concerns about the structural integrity of the PrK and the possibility of a catastrophic failure.”

“The Russians believe that continued operations are safe but they can’t prove to our satisfaction that they are, and the U.S. believes that it’s not safe but we can’t prove to the Russians’ satisfaction that that’s the case,” he added.

Russian teams believe the air leak was likely caused by high cyclic fatigue from micro vibrations, while teams at NASA think pressure and mechanical stress, residual stress, material properties of the module, and environmental exposure are all at play, according to SpaceNews.

The air leak was addressed in a recent report by NASA’s Office of Inspector General (OIG), which highlighted its true severity and the risk it poses to the crew. The OIG report stated that the two space agencies can’t seem to agree on the point at which the leak should be considered unsustainable. NASA and Roscosmos met to discuss the ISS air leak, with NASA officials noting that Roscosmos “is confident they will be able to monitor and close the hatch to the Service Module prior to the leak rate reaching an untenable level,” according to the report.

“Although the teams continue to investigate the causal factors for the crack initiation and growth, the U.S. and Russian technical teams don’t have a common understanding of what the likely root cause is or the severity of the consequences of these leaks,” Cabana is quoted in SpaceNews as saying.

The rate of air leaking from the hole increased around a week before the February 14 launch of the Progress MS-26 cargo spacecraft, which docked to the aft end of Zvezda. The hatch that connects the module to the ISS remained open for five days as the crew offloaded the cargo from Progress MS-26 onto the space station, but was closed shut afterwards.

NASA and Roscosmos are currently monitoring the leak and preparing to close the hatch to the service module when access is not required in order to minimize the amount of air lost and isolate the leak itself from the rest of the space station. If required, the space agencies are prepared to permanently shut off the hatch should the leak rate became unmanageable. The ISS would function normally, but there would be one less docking port for spacecraft delivering cargo to the space station.

As the two space agencies continue to discuss the potential risk, the aging space station is inching closer to retirement within the next six years and its hardware may finally be giving in to the wear and tear of the harsh space environment.

Space Station Raises Orbit Avoiding Orbital Debris

The Progress 89 thrusters were fired at 20:09 UTC on Tuesday, November 19 for 5 minutes, 31 seconds, to raise the orbit of the International Space Station (ISS) to provide an extra margin of distance from a piece of orbital debris from a defunct defense meteorological satellite that broke up in 2015. The Pre-determined Debris Avoidance Maneuver (PDAM) was conducted in coordination with NASA, Roscosmos and the other space station partners.

Without the maneuver, ballistics officials estimated that the fragment could have come within around 2.5 miles of the station.

The maneuver had no impact on station operations and did not affect Thursday’s launch of the Progress 90 cargo craft from the Baikonur Cosmodrome in Kazakhstan.

[Operators attempting to utilize Amateur Radio aboard the ISS should make sure that the Keplerian orbital data in their tracking software has been updated since this change in orbit.]

Satellite Shorts From All Over

+ The space news website Space Daily carried a full article on Nov. 12 about the 50th anniversary of the launch of amateur radio satellite AO-7. As noted in anniversary articles by Frank Karnauskas, N1UW, AMSAT Vice President – Development, that have been published here in the AMSAT News Service bulletins [see above for this week’s installment], AO-7 is the world’s oldest active satellite. The Space Daily article, by reporter Clarence Oxford, incorporated a good share of Frank’s text from ANS issue #308 published on Nov. 3. (ANS thanks Space Daily for the above information.)

+ The Space Force wants its next fleet of GPS satellites to be smaller, cheaper and more resilient — and it’s looking to a mix of commercial and defense firms to help design those spacecraft. The program, expected to cost $1 billion over the next five years, comes amid growing concern from Pentagon and other government leaders about GPS vulnerability. The system, which guides weapons and helps military units navigate, has been a target for Russia in its war with Ukraine, using electronic warfare to jam signals on a regular basis. Users have also reported increased spoofing incidents, a method of manipulating GPS data to confuse a receiver about its location. A larger number of small satellites should make it harder for enemies to target the fleet and will ensure there’s a backup capability when they do, the Space Force says. (ANS thanks Defense News for the above information.)

+ Earlier this month, three tiny Australian satellites from Curtin University’s Binar Space Program burned up in Earth’s atmosphere. That was always going to happen. In fact, Binar means “fireball” in the Noongar language of the First Nations people of Perth. But these CubeSats, known as Binar-2, 3, and 4, entered the atmosphere much sooner than originally planned. They only lasted for two months – a third of what was expected. Recent high solar activity has been causing an unexpected headache for satellite operators in the last few years, and it’s only increasing. (ANS thanks Science Alert for the above information.)

+ China has taken another step toward its crewed lunar goals by successfully testing fairing separation for its Long March 10 moon rocket series. The fairing separation test was conducted recently, according to a Nov. 20 statement from the China Academy of Launch Vehicle Technology (CALT). The separation test is one of a number of milestones needed in order to get the Long March 10 ready for flight, with a first launch to low earth orbit currently targeted for 2026. China has committed to the goal of getting a pair of its astronauts onto the lunar surface by 2030. (ANS thanks Space News for the above information.]
