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.

SDR Gen 2 Ad - 2026


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.

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.

Satellite Shorts from All Over

+ Roscosmos launched Progress 94 cargo spacecraft at 11:59 UTC (7:59 a.m. EDT) on Sunday, March 22, aboard a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan, carrying approximately three tons of food, fuel, and supplies for the Expedition 74 crew aboard the International Space Station. The spacecraft was originally expected to dock autonomously at the space-facing port of the Poisk module on Tuesday, March 24, following a two-day flight. Shortly after reaching orbit, one of its two KURS automated rendezvous antennas failed to deploy as planned, though all other systems continued to operate normally. As a result, cosmonaut Sergey Kud-Sverchkov manually piloted the spacecraft during final approach using the TORU remote control system from inside the Zvezda Service Module. Progress 94 successfully docked at 13:40 UTC (9:40 a.m. EDT) on Tuesday, March 24, completing the resupply mission despite the earlier anomaly. The spacecraft is expected to remain docked for about six months before departing the station for a planned destructive re-entry, disposing of trash loaded by the crew. (ANS thanks NASA for the above information)

+ About a month after an onboard anomaly caused a loss of contact with the Proba-3 Coronagraph spacecraft, mission controllers have successfully re-established communication. The Villafranca ground station in Spain, operated by the European Space Agency (ESA), received telemetry from the spacecraft, confirming it is once again transmitting health and status data. The Coronagraph is currently in a stable safe mode while engineers conduct detailed system checks to assess any potential damage. Its solar panel is properly oriented toward the Sun, allowing essential systems to remain powered and the battery to recharge. After weeks exposed to extreme cold, the spacecraft’s components will require time to warm up before normal operations can resume. Mission officials say the recovery is an encouraging milestone, though careful analysis and gradual recovery steps will be required before the mission can fully return to nominal activities. (ANS thanks the ESA for the above information)

+ NASA’s Double Asteroid Redirection Test (DART) mission has demonstrated that a kinetic impact can alter the motion of an asteroid system, with new analysis confirming effects beyond the initial impact. The 2022 impact into the small asteroid Dimorphos not only shortened its orbit around the larger asteroid Didymos, but also slightly changed the motion of the entire binary system around the Sun. Scientists measured a change in orbital speed of about 11.7 microns per second, a tiny shift that could have significant long-term implications for planetary defense. The impact generated a cloud of ejecta that enhanced the momentum transfer, effectively doubling the push delivered by the spacecraft. Observations from both professional and amateur astronomers, including stellar occultation campaigns, were critical in confirming these results. Researchers note that even such small orbital changes, if applied early enough, could be sufficient to deflect a potentially hazardous asteroid away from Earth. (ANS thanks Space.com for the above information)

+ A unique NASA astronomy satellite may soon undergo an unprecedented rescue attempt as it faces an early end in orbit. The Neil Gehrels Swift Observatory, launched in 2004 to study gamma-ray bursts, has been out of operation for more than a month and is gradually losing altitude due to atmospheric drag. NASA has awarded a $30 million contract to Katalyst Space Technologies to develop a robotic servicing spacecraft that will attempt to rendezvous with Swift and raise its orbit, extending the mission’s life. The planned rescue mission, scheduled for launch as early as June, would mark one of the first commercial attempts to dock with and service a satellite not originally designed for in-orbit repair. Engineers face significant challenges, including tight timelines, uncertain spacecraft conditions, and the risks associated with docking two large objects in low-Earth orbit. If successful, the mission could demonstrate a lower-cost approach to satellite servicing while preserving a valuable scientific asset. (ANS thanks Ars Technica for the above information)

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.

Ten-Koh 2 Satellite With Linear Transponder Update

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. Ten-Koh 2 currently only transmits very weak CW data on 435.860 MHz.

Ten-Koh 2 Keplerian data (TLE) are now available in the regular satellite catalog under catalog number 68261.

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.

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.

IARU Coordinates Two New Amateur Satellites

The International Amateur Radio Union (IARU) Satellite Frequency Coordination Committee has recently completed frequency coordination for two CubeSat missions: Taiwan’s Lilium-4 and Montenegro’s Luca-01. These coordinations ensure that the satellites can operate without interfering with other space-based communications, paving the way for their upcoming launches and contributions to scientific research, education, and ham radio communities worldwide.

Lilium-4, a 6U CubeSat developed by National Formosa University is set to enhance amateur radio connectivity and optical experimentation in space. The satellite, with callsign BN0YCA, will feature a 1200 bps AX.25 APRS digipeater on 145.825 MHz for global intercommunication among radio enthusiasts. It also includes UHF telemetry downlink at 437.850 MHz and a high-bandwidth S-band downlink at 2405.0 MHz for monitoring an onboard optical payload. Additional capabilities involve a V/U repeater with uplink at 145.980 MHz and downlink at 435.250 MHz, plus GNSS positioning using the L1 signal at 1575.42 MHz. The mission focuses on student-led studies of space-to-ground optical signal acquisition, with unencrypted telemetry encouraging public participation in decoding and link-budget validation. IARU coordination for Lilium-4 was finalized on January 31, 2026, following a submission in late December 2025. The satellite is slated for launch no earlier than mid-March 2026 aboard a SpaceX rocket from Vandenberg Space Force Base, targeting a 510 km polar orbit.

Luca-01 represents Montenegro’s entry into amateur satellite technology, spearheaded by Montenegro Space Research. This 1U CubeSat is designed for educational outreach, equipped with a charged particle sensor and a miniature camera to capture Earth’s surface images. It will transmit special Slow Scan Television (SSTV) images and telemetry data to engage radio amateurs, students, and schoolchildren, using an open protocol for easy reception with affordable equipment. The mission aims to inspire young people in amateur radio and space science, including efforts to image various orbital objects. Downlinks have been coordinated on UHF frequencies: 437.180 MHz primary and 436.150 MHz spare, employing GMSK modulation at rates between 2.4 kbps and 19.2 kbps. Coordination was completed on March 13, 2026, after an application submitted on February 6, 2026. Luca-01 is planned for a Roscosmos launch from the Vostochny Cosmodrome into a 500-600 km Sun-synchronous orbit.

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.

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.

The mission, called “Stairway to Seven,” was the seventh flight for Alpha, which suffered two major mishaps during 2025. The first occurred during the “Message in a Booster” mission last April, which carried a technology-demonstrating satellite for Lockheed Martin but failed to deliver it to orbit after an anomaly occurred during stage separation. Then, last September, an Alpha first stage exploded on the stand during prelaunch tests. This mishap added months to the mission development timeline as the company investigated a cause and got another booster ready for flight. Alpha Flight 7 achieved nominal performance and validated key systems ahead of the Block II configuration upgrade. This test flight also delivered a demonstrator payload for Lockheed Martin.

Kairos No. 3 Launch Failure Destroys NUTSAT-3

The third time was not the charm for Space One’s Kairos rocket.

Kairos launched for the third time ever on Thursday, March 5, lifting off from Space One’s Spaceport Kii in Wakayama Prefecture at 02:10 UTC (11:10 a.m. local time in Japan). But it was all over about two minutes later.

“Kairos No. 3 was launched on March 5, 2026, at 11:10:00 a.m., but we determined that mission success was difficult and implemented flight termination measures,” Tokyo-based Space One said via X on Wednesday evening (in Japanese; translation by X).

Among the Kairos No. 3 payloads was NUTSAT-3, a 3U CubeSat created with support from National Formosa University and dedicated to amateur radio service. The satellite, was designed to provide FM voice repeater, APRS, and telemetry services to the global amateur satellite community.

In addition to the amateur radio mission, the NUTSAT-3 project was to have actively engaged students in mission data analysis, RF design performance of satellite radio communications, and community participation by encouraging public engagement through open telemetry data.

Ten-Koh 2 to be Deployed Soon

A Japanese amateur radio satellite, launched to the International Space Station (ISS) last October, will soon be deployed in a higher orbit.

After delivering about 12,000 pounds of supplies, scientific investigations, hardware, and other cargo to the ISS for NASA and its international partners, JAXA’s (Japan Aerospace Exploration Agency’s) uncrewed HTV-X1 cargo spacecraft departed the ISS on Friday, March 6. The spacecraft arrived at the space station on Oct. 29, 2025, after launching Oct. 25 on an H3 rocket from Japan’s Tanegashima Space Center.

The HTV-X1 spacecraft will boost itself to a 500km circular orbit where it will remain for more than three months acting as a scientific platform for JAXA’s experiments.

After attaining this higher orbit, HTV-X1 will deploy Ten-Koh 2, a 6U cubesat constructed by Nihon University carrying a variety of amateur radio experiments. These will include:

  • A linear transponder, developed by JAMSAT, that will operate two days each week (schedule to be announced). Transponder frequencies that have been coordinated with the International Amateur Radio Union (IARU) feature an uplink in the range 145.895-145.935 MHz with downlink 435.875-435.915 MHz.
  • Digitalker with pre-loaded audio to be transmitted at 435.895 MHz.
  • Transmission of pre-loaded digital images created in cooperation with students from the Faculty of Arts, also at 435.895 MHz.
  • Demonstration of microwave band communication technology at 5.8 GHz in the microwave band.
  • Tests of high-speed data transmission at 38.4 kbps in 4FSK.

Following the deorbit command, HTV-X1 will dispose of several thousand pounds of trash from the ISS during re-entry into Earth’s atmosphere, where it will burn up harmlessly. However, Ten-Koh 2 is expected to remain in orbit and active for approximately one year to 18 months.

Cambodian Students Blast Off With Satellite Training

Although space technology may have not been officially introduced into the Kingdom’s standard curriculum, the topic is taking center stage at the National Polytechnic Institute of Cambodia (NPIC), at the 2nd Session of the NPIC SCT Event: QO-100 and LEO Satellite Training, igniting a passion for space communication among students.

The training, from February 26 to March 3, is transforming the campus into a hub of innovation.

Building on their past success of a 12,076-kilometre transmission to Antarctica via the QO-100 satellite, this year’s training elevates the challenge by focusing on Low Earth Orbit (LEO) satellites.

Students are actively engaged in hands-on learning, constructing and utilizing homemade antenna systems to track these fast-moving satellites across the sky, according to organizers.

International specialists from Japan, France and Australia are providing mentorship, guiding students through the complexities of installing ground stations and communicating with a variety of satellites, including the geostationary QO-100 and LEO satellites like RS-44 and SO-50.

“I wanted to show Cambodian students that space technology is accessible. Watching them successfully track an LEO satellite today proves that our youth are ready for the future,” said Jorge Paulo, a French Marine Electronics and Telecommunications System expert.

Mori Mikio, an amateur radio satellite technician from Japan, emphasized the event’s impact, highlighting how the real success is not just in the technical milestones, but in witnessing the passion of the participants.

“Seeing students successfully track LEO satellites with homemade antennas is a powerful reminder of why this event exists,” he said.

Reth Sengvisoth, one of the organising committee members, shared his satisfaction with their efforts. He said the months of planning and coordination went into bringing this international training to life.

Changes to AMSAT-NA TLE Distribution for March 6

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/.

URGENT MESSAGE: From TS Kelso of CelesTrak “[The US Space Force 18th Space Defense Squadron] will run out of 5-digit catalog numbers at 69999 not 99999, which is estimated to occur around 2026‑07‑20 (we’re currently at 68014). At that point, newly cataloged objects will have 6-digit catalog numbers of 100000+ and GP data will not be available for them using the TLE format. CelesTrak developed new formats that removed this limitation (and finally fixed the Y2K problem) in May 2020 and immediately began providing GP data in those formats for software developers. The same limitations apply to the legacy fixed-field SATCAT. Follow @TSKelso on Bluesky for the latest updates, tutorials, and changes as we approach this transition. Spread the word!”

AMSAT is presently alpha testing dissemination of orbital data aka “General Perturbations Data” or “GP Data” in formats that do not have the 5 digit object number limitation and will solicit public help for beta testing in April 2026. Many software packages used by hams already accept at least one of the new formats, and we would like to work through any issues before new satellites arrive without TLE sets. AMSAT will continue to disseminate TLE data for all satellites cataloged below 69999 indefinitely.

NOAA Cat ID 67291 has been renamed “RS95S (QMR-KWT-2)”

The following satellites have been removed from this week’s AMSAT TLE Distribution:

RSP-03 NORAD Cat ID 65732 Decayed from orbit on or about 16 February 2026
BOTAN NORAD Cat ID 65942 Decayed from orbit on or about 03 March 2026
MO-122 NORAD Cat ID 60209 End of mission, last telemetry 25 August 2025

NASA Reveals Astronaut Who Required Evacuation From ISS

NASA astronaut Mike Fincke, KE5AIT, Crew-11 pilot and commander of the International Space Station’s (ISS) Expedition 74, has revealed that it was his medical issue that prompted the evacuation of the four Crew-11 astronauts from the space station in January.

NASA astronaut Mike Fincke, KE5AIT (Credit: NASA)

The exact nature of his ailment remains undisclosed, but Fincke’s statement clarified that the issue, while not considered an emergency, required “advanced medical imaging not available on the space station.” As a result, Fincke and his crewmates — NASA astronaut Zena Cardman, KJ5CMN, Japanese space agency astronaut Kimiya Yui, KG5BPH, and Roscosmos cosmonaut Oleg Platonov — returned to Earth aboard the Crew Dragon “Endeavour” on Jan. 15, about a month earlier than originally planned.

The issue arose on Jan. 7, while Fincke and Cardman were preparing for an upcoming spacewalk. “The agency is monitoring a medical concern with a crew member that arose Wednesday afternoon aboard the orbital complex,” NASA officials said in an emailed statement on Jan. 7, declining to elaborate on the nature of that concern or the astronaut it affected. Then, on Jan. 8, the agency announced that Crew-11 would end early so the issue could be addressed here on Earth.

Crew-11 splashed down aboard Endeavour in the Pacific Ocean, off the coast of San Diego, on Jan. 15, leaving a skeleton crew of three aboard the ISS.

SpaceX’s Crew-12 mission was originally slated to launch in mid-February, with a typical handover period between them and Crew-11 expected after their arrival in low Earth orbit, allowing the newcomers time to acclimate to microgravity and life aboard the station. Efforts by SpaceX and NASA allowed for an earlier target date of their Falcon 9 launch aboard Crew Dragon “Freedom,” which lifted off Feb. 13 and returned the ISS to its regular crew complement of seven.

Satellite Shorts From All Over

+ In a statement on March 3, the Russian space agency Roscosmos said that its engineers have repaired a badly damaged launch pad at the Baikonur cosmodrome ahead of schedule, averting a potentially longer-term problem for supplying the International Space Station (ISS). The agency said a Progress cargo capsule is now scheduled to blast off to the ISS on March 22. The facility suffered a still unexplained mishap last November during the launch of a Soyuz capsule carrying two Russians and one American to the orbiting station. The pad is the only location where Russia can launch its manned Soyuz capsules, which are a mainstay transport and cargo vehicle for the station. (ANS thanks Radio Free Europe for the above information.)

+ SpaceX launched the 600th Starlink satellite of 2026 during predawn Falcon 9 rocket flight from Cape Canaveral on March 4. The Starlink 10-40 mission added another 29 broadband internet satellites into low Earth orbit. (ANS thanks SpaceflightNow for the above information. See the full article at https://spaceflightnow.com/2026/03/03/live-coverage-spacex-to-launch-29-starlink-satellites-on-falcon-9-rocket-from-cape-canaveral-10/.)

+ NASA announced on February 19 that it has reclassified Starliner’s Crew Flight Test (CFT) as a “Type A mishap” — the most serious kind, in the same category as the space shuttle Challenger and Columbia tragedies. CFT launched on June 5, 2024, sending NASA astronauts Suni Williams, KD5PLB, and Butch Wilmore to the International Space Station (ISS) for a planned 10-day stay. Starliner reached the orbiting lab safely. On the way, however, the spacecraft suffered multiple thruster failures and temporarily lost “six degree of freedom” control — the ability to precisely maintain its desired orientation and trajectory. NASA prolonged the orbital stay of Williams and Wilmore multiple times to study Starliner’s thruster issues. In the end, the agency decided to bring the capsule home uncrewed, which occurred on Sept. 6. Williams and Wilmore, meanwhile, stayed aboard the ISS. They came home on a SpaceX Crew Dragon capsule in March 2025, having spent about nine months in space instead of the originally planned 10 days. Both have since retired from the agency.
