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.

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. See the full article at https://www.msn.com/en-in/
