New “Ground Station” Software Streamlines Satellite Tracking and Decoding

A new open-source software project called “Ground Station” is gaining attention among amateur satellite operators as a unified platform for tracking, receiving, and decoding satellite signals. The software combines multiple functions typically handled by separate tools into a single system, offering a more streamlined approach to satellite operations.

Tracking programs, SDR control software, recording tools, and decoding utilities are often used together, sometimes requiring manual setup for each pass. “Ground Station” aims to simplify this process by automating the workflow from pass prediction through signal reception and decoding.

At its core, the software provides real-time satellite tracking using orbital data, along with automatic updates of satellite elements. It supports a variety of software-defined radios, allowing users to monitor and record signals from multiple satellites. The system also includes automated antenna rotator control and Doppler correction, helping keep signals centered during a pass.

The platform is capable of scheduling and executing satellite observations automatically, reducing the need for operator intervention. During a pass, it can record IQ or audio data and process common digital modes, including telemetry formats used by many amateur satellites. This is useful for operators interested in telemetry collection, CubeSat monitoring, and general satellite experimentation.

In addition to amateur radio satellites, the software integrates with tools such as SatDump to decode weather satellite transmissions, including NOAA APT and other imaging formats. This expands its usefulness beyond traditional amateur satellites to include weather satellite reception and other downlink services commonly monitored by the amateur community.

“Ground Station” is an early-stage, actively developed open-source project available on GitHub at https://github.com/sgoudelis/ground-station. Users can learn more about the software and access installation instructions there. As development continues, it offers a path toward more fully integrated ground stations, lowering the barrier to entry for satellite reception while providing experienced operators with a flexible new tool to explore.

KrakenRF Announces Discovery Drive Az/El Rotator for Satellite Operations

KrakenRF has announced its Discovery Drive, a motorized azimuth/elevation antenna rotator now in a crowdfunding campaign on Crowd Supply. As of late March, the project has raised more than $117,000 toward its $314,550 goal, reaching approximately 37 percent of its funding goal with several weeks remaining in the campaign.

Discovery Drive is designed as a turnkey solution for satellite tracking using directional antennas such as dishes and Yagis. The unit arrives fully assembled and weatherproof, eliminating the need for mechanical assembly or custom controller integration. Setup consists of mounting the rotator to a mast or tripod, applying 12 V power, connecting via Wi-Fi or USB, and aligning the system to true north.

The rotator is intended to support a range of satellite operations, including polar-orbiting weather satellites such as METEOR-M2 and MetOp, as well as CubeSat and amateur radio satellite tracking. KrakenRF also highlights additional experimental applications, including hydrogen line radio astronomy using compatible dish systems and software such as Stellarium.

A recent video review from the SaveItForParts YouTube channel demonstrates a prototype unit in operation, including setup with a Discovery Dish and reception of multiple weather satellites. The video also shows use with a handheld Yagi antenna, with future testing of amateur radio satellites anticipated. The review is available at https://www.youtube.com/watch?v=A7FiVWaXuXE.

Discovery Drive integrates with commonly used satellite tracking software through a rotctl-compatible network interface, allowing automatic control from applications such as SatDump, GPredict, and Look4Sat. It also supports USB serial control using the EasyComm II protocol via Hamlib. A browser-based web interface provides direct manual control and system configuration.

According to published specifications, the unit provides approximately ±1.5 degrees of pointing accuracy, with an azimuth range of ±360 degrees and elevation from 0 to 90 degrees. The system delivers up to 108 lb-in (12.25 N·m) of torque, supporting antennas up to approximately 11 pounds (5 kilograms). During the campaign, Discovery Drive is priced at $699, with a planned increase to at least $799 following the funding period. KrakenRF estimates a manufacturing timeline of approximately two months, followed by one to two months for fulfillment and delivery to backers.

Additional information is available at https://www.crowdsupply.com/krakenrf/discovery-drive.

Artemis II to Deploy International CubeSats into High Earth Orbit

When Artemis II lifts off on NASA’s Space Launch System in early April, four international CubeSats will be carried into space inside the Orion stage adapter. The satellites will be deployed into High Earth Orbit approximately five hours after launch, following separation from the upper stage and the Orion spacecraft.

The CubeSats will ride within a ring-shaped adapter structure that connects NASA’s Orion spacecraft to the SLS interim cryogenic propulsion stage. After Orion separates and establishes a safe distance, an onboard avionics unit inside the adapter will control deployment, releasing each CubeSat at one-minute intervals. This system ensures the satellites are deployed safely and without interference as the stage continues on its trajectory.

Although Artemis II’s primary objective is to send four astronauts on a crewed lunar flyby, the CubeSats will carry out independent scientific and technology demonstration missions. By flying as secondary payloads, these satellites provide additional research opportunities without affecting the main objectives of the mission.

Participating space agencies include the German Aerospace Center, the Korea Aerospace Administration, the Saudi Space Agency, and Argentina’s National Commission on Space Activities. The four CubeSats are named TACHELES from Germany, K-RadCube from South Korea, Space Weather CubeSat-1 from Saudi Arabia, and ATENEA from Argentina.

Each satellite is designed to carry out a unique mission. Germany’s TACHELES will study the effects of the space environment on electrical components, helping inform future deep-space systems. Other payloads will focus on radiation measurements, space weather monitoring, and validation of new technologies in a High Earth Orbit environment.

NASA officials note that CubeSats offer a relatively low-cost method for testing new technologies, though their small size presents challenges for long-duration missions. The Artemis II CubeSat program highlights the growing role of international cooperation under the Artemis Accords, while expanding access to space and enabling new scientific investigations beyond Earth orbit.

Digital Modes on FO-29 Not Permitted per Licensing Restrictions

Fuji-OSCAR 29 (FO-29 / JAS-2), the Japanese amateur radio satellite launched in August 1996, has entered a period of full sunlight, resulting in renewed and more frequent transponder activity. The inverting analog transponder operates with an uplink passband of 145.900–146.000 MHz (LSB) and a downlink of 435.800–435.900 MHz (USB), along with a CW beacon at 435.795 MHz. The satellite’s 1-watt PEP output is shared across the 100 kHz bandwidth, making careful power management essential for all users.

Although the FO-29 linear transponder is technically capable of passing narrowband digital signals such as FT8, FT4, PSK31, or Olivia, such operations are not permitted under the satellite’s original licensing from Japanese authorities. The transponder is explicitly licensed for SSB and CW modes only. This restriction stems from the satellite’s operational permit issued by Japan’s Ministry of Internal Affairs and Communications (MIC), which does not authorize digital emissions on the linear transponder frequencies.

Japanese license information indicating emission modes A1A (CW) and J3E (SSB)
are the only modulations permitted in the linear transponder downlink.

Operators attempting digital modes risk non-compliance with international amateur radio etiquette and could contribute to transponder overload, distortion, or temporary shutdowns—issues exacerbated by the high-duty-cycle nature of many digital signals.

AMSAT urges all users to limit their operations on FO-29 to SSB and CW and to practice good satellite etiquette:

• Use the minimum power necessary to produce a readable downlink signal.
• Ensure your downlink signal strength does not exceed the CW beacon level.
• Monitor the transponder before and during your transmission; if the beacon weakens or the passband becomes noisy, reduce power immediately.
• Keep signals clean and within the passband.

Share the limited resource responsibly so that the maximum number of amateurs worldwide can enjoy FO-29 while it remains active.

With the satellite now enjoying extended full-sunlight operation in 2026, this is an excellent time to explore its capabilities through permitted modes. Experimentation with unauthorized modes is discouraged to preserve the satellite’s health and comply with licensing.

SpaceX Plan For 1 Million Centers Poses Dangerous Risk

A SpaceX plan for 1 million orbital data centers proposes a massive constellation of sunlit objects that could severely impair ground-based astronomy and increase atmospheric pollution through frequent reentries in the upper atmosphere.

Astronomers warn that these 100-meter-long structures will remain illuminated even at midnight. This constant visibility threatens observations at ground-based observatories, such as the Vera Rubin Observatory and the Extremely Large Telescope currently under construction in Chile.

These orbital data centers, potentially 100 meters long, create persistent light streaks that obstruct astronomical research. Positioned in high-inclination orbits at 500-2,000 km, they remain illuminated by sunlight even at midnight, significantly outshining traditional broadband satellites.

Astronomers have filed formal objections with the FCC regarding the January 30 application. This new constellation poses a challenge unlike any encountered in the commercial space era, undermining years of progress.

Further, this much hardware results in one spacecraft burning up in the atmosphere every three minutes. This mass incineration releases dangerous concentrations of aluminum oxide and lithium, potentially depleting the protective ozone layer and altering global temperatures.

Environmental experts highlight risks, but the FCC’s fast-track approval process bypasses standard environmental reviews, placing the burden of proof on the scientific community to prevent damage.

Astronauts Complete Prep For New ISS Solar Array

Two NASA astronauts prepared the International Space Station (ISS) for the addition of a new solar array on the first U.S. spacewalk in almost a year.

Expedition 74 crewmates Jessica Meir and Chris Williams, KJ5GEW, ventured outside of the space station’s Quest airlock at 1252 UTC on Wednesday, March 18 to install a mount for an advanced power-producing solar panel. The pair worked on the left (or port) side of the space station’s backbone truss, where they first assembled and then attached the bracket structure that will support an ISS Roll-Out Array (iROSA), to be installed on a future spacewalk.

International Space Station for the addition a new solar array during
a spacewalk on Wednesday, March 18, 2026. (Image credit: NASA)

NASA had scheduled for the iROSA kit to be installed during a spacewalk in January, but one of the then-assigned spacewalkers, Mike Fincke, KE5AIT, had an undisclosed medical issue that required the excursion to be canceled and he and his crewmates to return to Earth a month early.

The space station’s original solar arrays have degraded, having exceeded their 15-year service life. When all of them are in place, the new iROSAs will increase the orbiting lab’s electricity supply by 20% to 30%. The additional power on the ISS will help support expanded commercial activities and the upcoming transition from the ISS to commercially operated space stations.

Wednesday’s spacewalk ended at 19:54 UTC, 7 hours and 2 minutes after it began.

Ten-Koh 2 Satellite With Linear Transponder Deployed

The 6U CubeSat Ten-Koh 2 (also written as Tenkoh-2 or てんこう２) from Japan’s Nihon University was successfully deployed into orbit on March 11, 2026, at approximately 09:34 UTC. The satellite was released from JAXA’s new HTV-X1 cargo spacecraft using the HTV-X Small Satellite Orbital Deployer (H-SSOD) after the vehicle departed the International Space Station (ISS) on March 6 and raised its altitude to around 500 km. This marks the first use of the H-SSOD mechanism for satellite deployment from HTV-X.

Developed by the Okuyama Laboratory in the Department of Aerospace Engineering at Nihon University’s College of Science and Technology, Ten-Koh 2 builds on the legacy of its predecessor, Ten-Koh (launched in 2018). The mission focuses on low-Earth orbit environmental observations to gather data for future space development, alongside in-orbit demonstrations of next-generation communication technologies. Key goals include evaluating high-speed data transmission and enabling global access for amateur radio operators to collect telemetry and experiment with the payloads.

The satellite carries an amateur radio payload coordinated by the International Amateur Radio Union (IARU) and supported by JAMSAT (Japan Amateur Satellite Association):

• V/U Linear Transponder (inverting, 40 kHz bandwidth):
  • Uplink (LSB): 145.895–145.935 MHz
  • Downlink (USB): 435.875–435.915 MHz
• Additional Downlinks/Experiments:
  • CW beacon, Digitalker, AFSK 1.2 kbps, GMSK up to 19.2 kbps on 435.860 MHz
  • High-speed experiments (GMSK 4.8–19.2 kbps, 4FSK 38.4 kbps) and photo/picture downlinks on 435.895 MHz
  • 5.839 GHz CW beacon for microwave-band communication demos (SHF experimenters take note—this provides a great target for testing dishes, feeds, and LNAs)

The transponder is expected to operate on a scheduled basis (initially two days per week, with details forthcoming from the team). Operations began shortly after deployment, with the university’s ground station confirming reception of the CW beacon for basic telemetry (voltage, temperature, etc.).

Post-deployment updates from the Okuyama Lab indicate the signal level is currently weaker than anticipated, prompting ongoing monitoring and appeals for reception reports via networks like SatNOGS to aid diagnostics and performance assessment. Early passes over Japan and other regions have yielded mixed results, with some operators reporting no signals yet, while preliminary TLEs (e.g., temporary NORAD 98542) are circulating for tracking.

FO-29 Enters Full Sunlight: Veteran Satellite Sees Renewed Activity in 2026

Fuji-OSCAR 29 (FO-29), also known as JAS-2, the Japanese amateur radio satellite launched in August 1996, has entered a new operational phase as of early March 2026. Now approaching its 30th anniversary in orbit, the satellite—long limited by failed batteries—relies entirely on solar panel illumination for power, meaning it only functions during sunlight periods and shuts down in eclipse.

In February 2026, the FO-29 control team (operated from Japan) continued scheduled activations of the linear transponder, with commands sent on specific dates to turn it on for limited windows. Operators noted the unstable situation due to the satellite’s age, with activations sometimes failing if the onboard voltage didn’t respond quickly enough. The transponder operates in Mode V/u (inverting SSB/CW): uplink LSB 145.900–146.000 MHz, downlink USB 435.800–435.900 MHz, with a CW beacon on 435.795 MHz.

Around March 9, 2026, when FO-29 transitioned into a full-sunlight orbit season. This eliminates periodic eclipses, allowing continuous operation as long as solar panels receive light. AMSAT highlighted this in early February bulletins, noting that shadow duration had decreased dramatically (from ~20 minutes to ~1 minute per orbit by mid-February), leading to the full-sun entry on March 9.

SatNOGS observers reported recent CW beacon and telemetry receptions as of March 12–13, 2026, with stations like EA5WA and DL7NDR logging data. On March 13, 2026, amateur operators reported successful SSB and CW QSOs during passes, including busy activity with calls from Japan (e.g., JO1XOK, JE6TSP), China (e.g., BA4QNR, BD5EUA, BG5FWV), and others (e.g., E27DPX). One operator described a “very busy pass” with multiple contacts, and another logged several SSB and CW exchanges despite windy conditions affecting reception.

AMSAT’s live linear satellite summaries and status pages list FO-29 as active under full sunlight conditions, with the transponder remaining on until voltage drops below safe thresholds—no longer an issue in continuous sun. The digital modes (1k2/9k6 BBS) remain inactive, and the Digitalker on 435.910 MHz is rarely used.

This full-sunlight period offers a welcome revival for one of the oldest active analog linear transponders in the amateur fleet. Enthusiasts are encouraged to monitor, log contacts via the AMSAT OSCAR Status Page, and share reports to help track performance.

Changes to AMSAT TLE Distribution for March 13, 2026

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 daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

Ten-Koh2 has been added to this week’s distribution.

Satellite Shorts from All Over

+ NASA held a live news conference on March 12 following the Artemis II Flight Readiness Review, confirming the SLS rocket and Orion spacecraft remain in the Vehicle Assembly Building at Kennedy Space Center for final prep work. Repairs to the upper stage helium system (from a quick-disconnect seal issue) are complete, with rollout to the pad expected later this month. The mission targets the first crewed lunar flyby in over 50 years, now aiming for early April launch opportunities (starting April 1) (ANS thanks NASA for the  information. https://www.nasa.gov/2026-news-releases)

+ NASA’s retired Van Allen Probe A (launched 2012) made an uncontrolled reentry over the Pacific west of the Galapagos on March 11. Most of the spacecraft burned up, with a low risk (1-in-4,200) of debris causing harm; its twin Probe B remains in orbit but non-operational. The probes studied Earth’s radiation belts for years. (ANS thanks AP for the  information. See the full article at https://www.kbtx.com/2026/03/11/old-nasa-science-satellite-plunges-back-earth)

+ Roscosmos completed repairs to the damaged Soyuz pad (Pad 31) at Baikonur Cosmodrome after a November 2025 incident where an unsecured service structure fell during launch. Over 150 personnel restored the site; first relaunch (Progress cargo to ISS) targeted for March 22. (ANS thanks Ars Technica for the information. See the full article at https://arstechnica.com/space/2026/03/rocket-report-spacex-launch-prices-are-going-up-russia-fixes-broken-launch-pad)

+  The European Space Agency has confirmed that its Coronagraph spacecraft, part of the Proba-3 solar observation mission, has gone silent following an onboard anomaly in mid-February 2026. The incident led to the loss of attitude control, preventing the satellite’s solar panels from facing the Sun and draining its battery. The spacecraft has since entered survival mode, cutting off all communication with Earth.(ANS thanks MSN for the information.
