World Radio Conference 2023 Will Impact Amateur Satellite Service

The World Radio Conference in 2023, WRC-23, will take place on November 20 – December 15 in Dubai, United Arab Emirates. Some decisions made during the conference will affect Amateur Radio and the Amateur Satellites service.

Representing Amateur Radio at the conference is the IARU, the International Amateur Radio Union, The two most pressing issues affecting the Amateur Satellite Service are:

Additional measures to protect the radionavigation-satellite (space-to-Earth) in the 1240 – 1300 MHz band from amateur interference.  As in most microwave allocations, the Amateur Service is secondary and must avoid interfering with primary services operating in the band, even if they are introduced later.  An ITU Radiocommunication sector Recommendation that contains guidance for administrations is in the final stage of development. If an agreement is reached prior to WRC-232, it should complete work on the item.

Identification of the 10 – 10.5 GHz band for International Mobile Telecommunications (IMT) in ITU Region 2, including a primary allocation to the mobile service.  The IARU opposes the introduction of IMT in the band and has some allies among administrators within and outside of Region 2.

ARISS USA Team Names Director of Education

Tanya C. Anderson has been selected as Director of Education for Amateur Radio on the International Space Station, Inc. (ARISS-USA). Tanya has been a classroom educator for 18 years, the last 16 years teaching middle school science at St. Joan of Arc in Lisle, Illinois. Her science curricula cover earth and space science, life science, and physical science. Her career focus has been curriculum development in various fields of science.

In addition to her responsibilities as a middle school educator, Tanya has shown her passion as a results-oriented leader in a myriad of science, technology engineering, arts, and math (STEAM) initiatives such as NASA HEAT 2022 where she helped develop and test science curriculum for teaching heliophysics and system science. She also has served as a team leader in NASA’s Teaching from Space Microgravity Education Program, working with students to create an experiment that was tested on NASA’s microgravity aircraft.  Tanya is also a NASA Airborne Astronomy Ambassador and a Space Foundation International Teacher Liaison.  She received the 2015 Civil Air Patrol Aerospace Educator of the Year.

When informed of her selection, Tanya exclaimed, “I am excited to be a part of the ARISS organization and cannot wait to see what the future holds for amateur radio as commercial space stations are built and lunar exploration evolves. I look forward to sharing my passion for STEAM and space education with other educators while we work together to inspire, engage, and educate the next generation.”

Tanya currently holds a Technician Class amateur radio license, with the callsign KD9BQZ, and has attended the ARRL Teacher Institute on Wireless Technology Workshop. In 2014, Ms. Anderson organized and held a successful ARISS contact involving the entire student body at St. Joan of Arc School. For the ARISS contact, she developed an extensive curriculum preparing students for their ham radio connection with Astronaut Alexander Gerst. Her first-ever ham radio contact was with Astronaut Gerst on the ISS. Tanya’s passion for education and ham radio continued outside the classroom as a troop leader for 6 years with the Boy Scouts of America. Tanya used her educational and amateur radio abilities to immerse the scouts in STEAM as well as help facilitate scout participation in Jamboree on the Air and radio merit badge classes.

ARISS-USA Executive Director, Frank Bauer remarked on Tanya’s selection, “Competition for this position was extensive and selection was challenging, given the number of truly outstanding candidates. We are thrilled to welcome Tanya to our ARISS leadership team. Her leadership experience, passion and educational prowess will serve ARISS well, guiding our education volunteers and supporting the implementation of the ARISS 2.0 vision–to develop more comprehensive educational outcomes for youth and life-long learners.”

Updated AMSAT Tri-Fold Brochure Now Available

Originally created by JoAnne Maenpaa, K9JKM, the AMSAT tri-fold brochure has always been a favorite handout for use at hamfests and club presentations. Over the past few years, many things have changed at AMSAT and with the satellites we operate. Unfortunately, we did not update the brochure to keep up with the times.

But, now with the pandemic largely behind us, in-person hamfests and club meetings are in full swing and the need for an update to the brochure was apparent. Happily, the brochure has been updated and available for viewing and downloading. You will find on the AMSAT website under “Get Involved/AMSAT Ambassador Program” from the top menu. You will find the link to the file in the “What resources are provided to AMSAT Ambassadors?” section of that page.

Looking for more information to share? The electronic brochure “This is AMSAT” is also available for download at https://tinyurl.com/This-is-AMSAT. “This is AMSAT is 18 pages jam-packed with information about our youth and education programs, engineering activities and member services. It’s only 1 Mb big so its easy to share with your friends by email, and its mostly jargon-free so everyone can understand what they’re reading!

Changes to AMSAT-NA TLE Distribution for September 8, 2023

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

The following satellite has decayed from orbit and has been removed from this week’s AMSAT-NA TLE distribution:

AAUSAT 4  NORAD Cat ID 41460  Decayed from orbit 06 September 2023

+ Ironic: Clearspace-1, an ESA mission developed by a Swiss startup firm, is planned to demonstrate a system for deorbiting space junk. Its target is VESPA, a payload adapter left over from a 2013 Vega launch. But before Clearspace-1 could launch and reach its target, VESPA was hit by… you guessed it — a piece of space junk. Clearspace-1 will still attempt to reach and deorbit the largest remaining chunk of VESPA. But perhaps a better plan than after-the-fact debris removal is to equip satellites and rocket stages with technology to deorbit themselves after mission completion?

Two Awards Available from AMSAT-UK Regarding EO-88’s Impending Re-Entry

As you may be aware, Solar Cycle 25 has already shown that we cannot yet predict what the sun will be doing with any great accuracy.

Sunspots, X-class solar flares and CMEs (coronal mass ejections) are increasing in frequency and intensity on a daily basis.

The peak of Solar Cycle 25 was not expected until late 2024 or early 2025 but it may be coming earlier and have a higher intensity than was predicted.

One result of this increased activity is that the upper atmosphere and ionosphere of the earth becomes warmer and expands upwards. This means that spacecraft in low earth orbit experience more drag or resistance as a result of the increase in the number atoms they are having to displace as they travel around the globe. As a consequence, the spacecraft loose more kinetic energy and start to descend lower in orbital height, which, of course, makes the problem worse and a fiery end to the spacecraft is hastened.

The actual effect is also dependant on the drag coefficient of the particular spacecraft…simply how much mass (the more the better) to how much surface area (the less the better). So in CubeSat terms, a 1U CubeSat, fairly full of stuff with a mass near the maximum of 1.3kg, will probably be better off than a half empty 3U CubeSat with deployable solar panels and other drag inducing protuberances.

All TLEs (Two Line Elements) include a parameter called drag, it is usually a very small number preceeded by four or more zeros! Although this parameter is calculated by the system, it is not usually precise or even stable, so cannot be used to accurately predict deorbit dates when looking forward many weeks/months. It can give us a guide though! Alarm bells should ring when we only see two leading zeros.

How does this effect our activities? Well for the FUNcube family, there are presently three active members!

FUNcube-1, AO-73 was launched almost ten years ago in November 2013 into an elliptical polar orbit of approx 682×595 km. Presently those numbers are around 640×570 km so probably not too much to worry about. The drag number from the TLEs is, at the time of writing, 0.000074, a good number.

The same applies to JY1SAT, JO-97. This was launched in December 2018 into a 573×590 km polar orbit. Presently those numbers are around 557×573 km and the current drag is listed as 0.000076.

Unfortunately, however, the same cannot by said for Nayif-1, EO-88. This spacecraft was launched in February 2017 into a 496×507 km polar orbit. Currently the orbit parameters show a height of around 320 km with the drag at 0.00319. It is now well below the ISS and much lower than at launch.

As mentioned, largely due to the random nature of the our star’s flux output on a day to day basis, it is not possible at this stage to accurately predict the likely deorbit date but it seems that it will certainly be before the end of this year. As the spacecraft continues to perform 100% nominally this is a great shame. Presently it is switching autonomously from high power telemetry when in daylight and with lower power telemetry and the transponder active when in darkness. The solar panels, battery and power system also continue to be reporting nominal numbers, essentially unchanged since the day of launch.

It will therefore be a really sad moment when re-entry occurs but in the meantime everyone is encouraged to use the spacecraft whilst it remains available.

To mark the event of EO-88/Nayif’s demise, AMSAT-UK is offering two awards. These will be individual framed certificates.

Firstly, to the station who submits the last telemetry to the FUNcube Data Warehouse and also to who “guesses” or calculates the re-entry time and date most accurately. Submissions for this award must be made to [email protected] before midnight (UTC) on July 4th 2023. So time is short to get your entries in. Good luck!

URESAT-1 Deployed

The URESAT-1 satellite, also known as HADES-B according to its ITU designation, successfully launched into space as part of the SpaceX Transporter-8 mission from Vandenberg AFB on Monday, June 12. The satellite is a joint effort between AMSAT-EA, URE (the Spanish equivalent of ARRL), private companies, and universities.

The URESAT-1 satellite, contained within the D-Orbit ION Orbital Transfer Vehicle (OTV), was not deployed directly from the Falcon-9 rocket. Instead, approximately one hour and twenty minutes after launch, the Falcon-9 released the OTV. URESAT-1 was deployed from the OTV at approximately 12:10 UTC on June 22, 2023. As of this writing, signals have not yet been received from the satellite.

One of the primary objectives of URESAT-1 is to serve as an FM voice and FSK data repeater. Equipped with a Slow Scan Television (SSTV) camera, the satellite will transmit live images as well as stored images at regular intervals. It also features a chess game, enabling players on Earth to engage in a game against the satellite. Periodically, the satellite will transmit updates on the state of the game, including the chess board, the last movement made, and whether the next move belongs to the players or the satellite.

The specified frequencies for communication with URESAT-1 are as follows: for uplink transmissions, 145.975 MHz or 145.925 MHz (auxiliary frequency) using FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps. For downlink transmissions, the frequency is set at 436.888 MHz, and modes include FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, and a voice beacon with the callsign AO4URE.

To provide further information regarding URESAT-1’s transmissions, the AMSAT-EA organization has made available a comprehensive document that can be accessed at the following link: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmissions+description.pdf

For those interested in decoding the telemetry, a Linux x86/ARM decoder is available for download at the following link: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_Linux_X86_ARM_v1.0.zip

A sample file containing the audio of a telemetry file can be found here: https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetry-chessboard_packet.wav

If URESAT-1 operates as intended, the project team plans to release a Linux program that will allow players to send their chess moves to the satellite, further enhancing the interactive experience.

Harbin Institute of Technology Developing New Lunar Amateur Radio Satellite

Lunar OSCAR II is a lunar amateur radio payload developing by a team consists of students in Harbin Institute of Technology and international amateur radio enthusiasts. Its baseline functions include telemetry, digital image downlink from an infrared camera, and digipeater with JT4G uplink/downlink. It will also provide chances for uploading and testing new waveforms and algorithms for radio communications and measurements in very long distance.

Amateur radio orbit determination experiments, for example Very Long Baseline Interferometry (VLBI), are also possible with these links.

Harbin Institute of Technology has previously successfully developed the first lunar amateur radio satellite, Longjiang-2 / DSLWP-B. (LO-94) As a subsequent mission, Lunar OSCAR II will continue offering various resources for communications relay and amateur radio research, and promoting the cooperation of amateur radio communities.

The Lunar OSCAR II payload will be on board a lunar microsatellite with a volume of about 300x200x100 mm3 and a mass of about 14 kg and will utilize downlinks on UHF for telemetry and images using 250/500 baud GMSK with turbo codes and Digipeater using 4.375 baud $FSK with convolutional coding (JT4G). More information is available at https://by2hit.github.io/.

The satellite is planned for a launch from Wenchang in 2024.

A downlink on 437.750 MHz has been coordinated.

How Many Satellites Can We Safely Fit In Earth Orbit?

Just 10 years ago, a mere thousand or so operational satellites may have orbited our planet, but there will be tens or even hundreds of thousands a decade from now. Experts have been sounding alarm bells for years that Earth orbit is getting a bit too crowded. So how many satellites can we actually launch to space before it gets to be too much?

Jonathan McDowell, an astrophysicist and astronomer at the Harvard-Smithsonian Center for Astrophysics warns the first signs that things are getting a little too tense are, in fact, already present. “It’s going to be like an interstate highway, at rush hour in a snowstorm with everyone driving much too fast,” he told Space.com when asked what the situation in orbit will be like if existing plans for satellite megaconstellations such as SpaceX’s Starlink, OneWeb and Amazon Kuiper come to fruition. “Except that there are multiple interstate highways crossing each other with no stoplights.”

McDowell’s British colleague Hugh Lewis is another frequently heard voice of caution. In a post published on Twitter on Jan. 13, Lewis stated that “the overall number of conjunctions predicted for 2022 was 134% higher than the number for 2020 and 58% higher than 2021, exceeding 4 million.” That doesn’t mean that on 4 million occasions objects in space came close to a collision — just that managing traffic in space is getting much more complicated than it has ever been in the past.

Take SpaceX’s Starlink as an example. According to information submitted to the U.S. Federal Communications Commission (FCC) in December last year, SpaceX’s autonomous collision-avoidance system performed 26,037 orbital avoidance maneuvers with its Starlink satellites in the two-year period between Dec. 1, 2020 and Nov. 30, 2022. That means each Starlink satellite of the nearly 4,000 that have been launched to date performed, on average, 12 avoidance maneuvers during that time.

But the size of SpaceX’s current constellation is less than 10% of what the company plans to deploy. Within the next 10 years, the number of Starlink satellites in orbit may rise to 42,000. Add to that the up to 4,000 satellites that OneWeb wants to launch, another 3,200 of Amazon’s Kuiper craft and 13,000 satellites of China’s envisioned Guowang system, and it becomes obvious that things are set to get much more heated.

According to the FCC document, SpaceX claims that each of its satellites has a sufficient amount of fuel on board to perform 350 collision-avoidance maneuvers over its expected five-year lifetime. But that number could be reached remarkably soon, according to Lewis’ calculations. In short, less than five years from now, Starlink satellites may be running out of fuel in a shorter period of time than their designed lifetime because of the sheer number of avoidance maneuvers they will have to perform.

Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.

Quick list of scheduled contacts and events:

No contacts currently scheduled

The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

Comments on making general contacts

I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities.

Typical daily schedule

Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours

The crew’s usual waking period is 0730 – 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They’re usually free most of the weekend, as well.

SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements.

And don’t forget that the packet system is active.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

ARISS Radio Status

Columbus Module radios:
IORS (Kenwood D710GA) – STATUS – Configured. Default mode is for cross band repeater (145.990 MHz up {PL 67} & 437.800 MHz down).

Upcoming Satellite Operations

Adrian (AA5UK) is heading back to the Cayman Islands. He will be operating as ZF2AE/ZF8 from Little Cayman June 25 to June 29th (EK99wp). He plans to rent a car June 28th/29th and will try to make it to FK09 grid at the other end to the island, time permitting. He will operate from Grand Cayman as ZF2AE June 30th to July 3rd (EK99ki) with focus on cross Atlantic contacts via AO7, RS44, FO-29 and IO-117. He will be relocating to Seven Mile Beach to operate from July 4th – July 7th in EK99hi and will try to mix it up on the passes with focus on Western passes.

The gear will be FT-1634 with Alaskan Arrow antenna. For IO-117, he will be using an IC-7000. Operation will be holiday style. Please follow him on Twitter @ZF2AE and @AA5UK and watch for the latest announcements. He also plans to periodically operate HF with focus on RTTY, FT8/FT4 and other digital modes. QSL information on QRZ.com. LOTW preferred.

Hamfests, Conventions, Maker Faires, and Other Events

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

+ AMSAT Space Symposium and Annual General Meeting
October 20-21, 2023
Dallas, Texas

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

AMSAT Ambassador Clint Bradford, K6LCS, says,

“Think a 75-minute presentation on “working the easy satellites” would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!”

Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences. An email message received after a recent presentation:

“I really enjoyed Clint’s presentation last night. The fact that he had taken the time to research and know something about his audience and welcomed interaction made it very informative and enjoyable. This was a refreshing change from many canned YouTube presentations I’ve tried to watch, which were poorly done, fuzzy video or muddy audio, or a badly prepared presenter stumbling his way through, with any valuable info lost along the way. Thanks for hooking this one up.”

Satellite Shorts From All Over

+ For rocket geeks, an interesting video shows the dynamics of SpaceX’s new stage separation technique, which will be tested on Starship, separating the booster and upper stage without pusher pistons (like Falcon) or explosives (like many traditional rockets). The video may be found at https://www.youtube.com/watch?v=yesni8HUEA4 (ANS thanks The Orbital Index for the above information)

+ Although their identities have been widely circulated previously, the European Space Agency (ESA), on June 20, formally announced the personnel who will make up SpaceX Crew-7. They are NASA astronaut Jasmin Moghbeli, KI5WSL, commander; ESA astronaut Andreas Mogensen, KG5GCZ, from Denmark, who will serve as pilot; as well as JAXA astronaut Satoshi Furukawa, KE5DAW, from Japan, and Roscosmos cosmonaut Konstantin Borisov, from Russia, who will both serve as mission specialists. This crew will launch from Cape Canaveral in Florida later this summer on a SpaceX’s Crew Dragon, and will remain aboard the International Space Station (ISS) for approximately six months. (ANS thanks ESA for the above information)

+ Spei Satelles is a 3U CubeSat created by the students and teachers of the Polytechnic of Turin. During its stay in orbit, Spei Satelles will transmit a radio signal that can be received by amateurs. The signal contains messages of hope from the magisterium of Pope Francis. Spei Satelles (the Latin words for Satellite of Hope) operates in a sun-synchronous low Earth orbit at about 525 km of altitude from the Earth’s surface. At a frequency of 437.5MHz (Editor’s note – this satellite is not coordinated by the IARU and AMSAT encourages radio amateurs to decline to offer telemetry collection or other technical support to groups that launch satellites that are not IARU coordinated and do not offer amateur communications opportunities) it transmits GMSK at 9600 bit/s AX.25. Spei Satelles also contains a nanobook, a 2x2x0.2 mm silicon slab on which the images, speeches, and readings by Pope Francis on March 27, 2020, in the midst of the pandemic, were imprinted by nanotechnologies. The satellite hitched a ride aboard Space X’s Falcon 9 rocket launching from the Vandenberg Space Force Base in California on June 10, after being blessed by Pope Francis on March 29 at his General Audience in St. Peter’s Square. (ANS thanks Religion News Service and Polytechnic of Turin for the above information)

+ Congratulations to Olivier Tymkiw, HB9GWJ, on receiving AMSAT Rover Award # 077! To earn the AMSAT Rover Award, participants must accumulate a combined total of 25 points through various achievements in portable satellite operations outside their home grid square. The AMSAT Rover Award was established to recognize and honor the accomplishments of satellite operators who engage in rover operations. Rover operations involve the activation of grid squares outside one’s home grid, utilizing various satellite transponders and modes to establish communication links. A breakdown of the points system along with a list of past AMSAT Rover Award recipients can be found at https://www.amsat.org/amsat-rover-award/. Keep on roving, Olivier, and continue to inspire others in the AMSAT community!

New Satellite Distance Records

IO-117 continues to provide a lot of DX fun for amateur satellite operators. Numerous satellite operators have reported receiving the ARRL’s Worked All States and DX Century Club Satellite awards lately as well as CQ Magazine’s Worked All Zones Satellite award (25 of 40 zones are required for the satellite award). For an example about the distances that can be worked via this satellite in Medium Earth Orbit (MEO), two QSOs got very near the 13,000 km mark recently.

On February 11, 2023, Dave Fisher, KG0D, worked Lucky Bijanki, VU2LBW. The distance between KG0D in CN88kd and VU2LBW in MK82tv is 12,939 km.

Unfortunately for this claim, Hector Martinez Sis, W5CBF, worked Oleg Vakochine, A65BR, on January 29, 2023 at 21:00 UTC. The distance between W5CBF and A65BR is 12,996 km.

Note that only real-time QSOs will be considered for distance records. Under the ARRL’s current interpretation of their award rules, satellite QSOs involving delayed messaging or store-and-forward systems are not valid for WAS, DXCC, or VUCC. Thus, QSOs made over multiple orbits using this method will not be considered for inclusion in the AMSAT Satellite Distance Records archive.

Also please note that the distance calculator at k7fry.com/grid is used to calculate all distances for AMSAT records purposes. This may not provide the most accurate distance under the most recent geodetic datum standards, but it is a consistent reference.

Anyone who wants to claim a distance record via an amateur satellite should check the current list at https://www.amsat.org/satellite-distance-records/ and email n8hm at arrl.net if they complete a new record distance. Audio and/or video of the QSO is encouraged but not required.

Changes to AMSAT-NA TLE Distribution for March 2, 2023

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

This week there are no additions or deletions to the weekly AMSAT TLE
distribution.

AO-95 QRT

After a lingering illness of the battery, AO-95 passed away peacefully on December 23rd. While a miraculous return is always possible, it is not expected.

AO-95, known prior to launch as Fox-1Cliff to commemorate amateur satellite pioneer Cliff Buttschardt, K7RR, who became a silent key in 2007, launched on December 3, 2018 on a SpaceX Falcon 9 from Vandenburg Air Force Base. Shortly after deployment, the AMSAT Engineering team received nominal telemetry data from the satellite, but upon the first attempts at commanding, it was discovered that the receiver had failed for unknown reasons. Still, the satellite provided an easy to receive beacon and telemetry data for over four years before the NiCd batteries failed.

New Satellite Distance Records

A number of new distance records via satellite have been claimed over the past couple of months. First is the massively popular new MEO satellite IO-117. Burt DeMarcq, FG8OJ, worked Shigenori Nasu, JH8FIH, on November 25, 2022 at 08:22 UTC. The distance between FG8OJ in FK96hg63 in Guadeloupe and JH8FIH in QN14qi16 in Japan is 12,823 km.

Note that for future claims of IO-117, only live QSOs may be counted and not those completed over multiple orbits using the satellite’s delayed messaging capabilities.

A new distance record was also claimed via the QO-100 geostationary satellite. PT9AL in GG27os in Brazil worked XW4KV in Laos OK27jj on December 10, 2022 at 14:41 UTC. The distance between the two stations is 17,834 km, eclipsing the previous record held by PR8KW and YC5YC of 17,378 km.

Finally, FO-118, launched in December is a LEO satellite carrying three transponders. Familiar faces for the AMSAT Satellite Distance Records have claimed the initial record on all three transponders – the V/u FM transponder, the V/u linear transponder, and the H/u linear transponder (15 meter uplink). F4DXV and VE1CWJ completed transatlantic QSOs on all three transponders. On January 6, 2023 at 04:15 UTC, they completed a QSO via the V/u FM transponder and then switched over to the V/u linear transponder to complete a QSO there one minute later. VE1CWJ was in FN85do83sg and F4DXV was in JN04js20pr. They completed the sweep of all three transponders on January 30, 2023, when they completed a QSO via the H/u linear transponder at 17:16 UTC. VE1CWJ was in the same location while F4DXV was in JN04it22nt for this QSO, for a distance of 4,908 km.

Anyone who wants to claim a distance record via an amateur satellite should check the current list at https://www.amsat.org/satellite-distance-records/ and email n8hm at arrl.net if they complete a new record distance. Audio and/or video of the QSO is encouraged but not required.

Changes to AMSAT-NA TLE Distribution for February 2, 2023

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

AMSAT IT, in conjunction with the New England Sci-Tech STEM Education Center assembled a tiger team of software experts from the Olin College of Engineering, Boston Latin School and the Wilson Middle School to investigate the recent disappearance of AO-7 from www.amsat.org/tle/current/dailytle.txt and the legacy naasbare.txt files.

The team determined that AMSAT’s processing is not robust in the face of minor format differences in the source data received from the USSF’s 18th Space Defense Squadron. Specifically, the TLE data provided does not always include the leading zero in AO-7’s object number “07530”. The official report from the team’s leader : “My grandma would say that AMSAT’s software is just a little too persnickety”. A member of the tiger team agreed to adjust the update script to account for the vagaries of the 18th SDS data. A production quality fix is expected by March 1st, meanwhile manual monitoring and updates will keep AO-7 in the files.

There were no changes to the February 2, 2023 distribution.

Special thanks to our ARISS telebridge ground stations. Approximately 38% of the ARISS school contacts are handled by the ARISS telebridge stations. Thanks to following stations: AB1OC, IK1SLD, K6DUE, NA7V, ON4ISS, VK4ISS, VK4KHZ, VK5ZAI, VK6MJ, and ZS6JON.

The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

Comments on making general contacts

I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities.

Typical daily schedule

Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours

The crew’s usual waking period is 0730 – 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They’re usually free most of the weekend, as well.

SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements.

And don’t forget that the packet system is active.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Satellite Shorts From All Over

+ The FO-99 operation schedule for February is available at https://www.jamsat.or.jp/?p=2079 (Thanks to JAMSAT for this information)

+ A volunteer is being sought to take over the Gridmaster Heat Map on Twitter. Paul Overn, KE0PBR, has announced his intent to “retire” from the project that he has moderated there for the past three years. Paul has assisted many grid chasers by relaying information about rovers, and keeping tabs of which grids are in greatest need. Unless someone steps forward, Gridmaster Heat Map will disappear next month. Thanks to Paul for your valuable contribution to satellite operations! (ANS thanks Paul Overn,
KE0PBR, for this information)

+ A while ago, perhaps almost two years ago, I modified the LVBTracker firmware in my Fox Delta ST2-USB so that it would allow for more calibration points than just the min and max for azimuth. I had added a remote-control option to an old Yaesu G-450XL, but the output voltage was very non-linear, which led to terrible aiming of the antennas. With the mods I made to the firmware it now allows me to calibrate the controller at 0, 90, 180, 270, and 360 degrees and aiming is now rather accurate. I wrote about it here:

Fox Delta ST2 / LVBTracker Calibration Mods

+ SuitSat-1 (AMSAT-OSCAR 54) deployed from the ISS 17 years ago February 3rd. It played voice messages in languages recorded by the ARISS partners and students from around the globe. It also sent telemetry data. It was lost 15 days later. SuitSat came back to life in a 2021 short horror film! If you’d like to watch the Sci-Fi Horror short film “Decommissioned” based on the ARISS SuitSat, it can be found on YouTube at https://www.youtube.com/watch?v=TNtpdvfbTjA (Thanks ARISS for this information)
