PSLV-C62 Mission Experiences Anomaly

The Polar Satellite Launch Vehicle (PSLV)-C62 mission carrying the ‘Anvesha’/EOS-N1 satellite and 15 co-passenger satellites launched by India on Monday encountered an anomaly during the end of the PS3 burn stage with ISRO chairman V Naryanan stating that “a deviation in the vehicle’s flight path” was observed.

“A detailed analysis has been initiated,” the Indian Space Research Organisation (ISRO) posted on X.

ISRO Chairman V Narayanan said a disturbance was observed in the vehicle at the end of the third stage, which was otherwise proceeding as expected.

“Today, we have attempted the PSLV C62 / EOS – N1 Mission. The PSLV vehicle is a four-stage vehicle with two solid stages and two liquid stages. The vehicle’s performance near the end of the third stage was as expected. (However), near the end of the third stage, we are seeing increased disturbance in the vehicle. Subsequently, a deviation in the vehicle’s flight path is observed. We are analysing the data and will come back at the earliest,” Narayanan said.

This is ISRO’s first major launch of 2026. The mission aimed to place an Earth observation satellite into orbit from the First Launch Pad (FLP) at Sriharikota.

The mission was carried out by NewSpace India Limited and represents the ninth dedicated commercial mission to build and launch an Earth Observation satellite.

For the first time, a single Indian private company, Dhruva Space, based in Hyderabad, contributed seven satellites to the mission. Chaitanya Dora Surapureddy, CFO and Co-founder of Dhruva Space, said they also launched four satellites that they built.

“We launched four satellites that we have built, three for customers and one for us, and we also help other companies with part of the integration of the satellite onto the rocket. Essentially, a total of nine of our systems, which we have built, are going onto the rocket. So, quite exciting that that’s a good number,” he said.

Surapureddy said their satellites are for low-data-rate communication, which can be utilised by amateur radio operators.

“The satellites that we launched are all for low data rate communication. Amateur radio operators can utilise it towards that, and also a good demonstration for these satellites, and also for low data rate communication that can be done,” he added

Message to U.S. Educators: ARISS Contact Opportunity Call for Proposals

The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between July 1, 2026 and December 31, 2026. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

The deadline to submit a proposal is February 27, 2026.  Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An informational webinar session will be held on February 5, 2026 at 8 PM ET.

The Zoom link to sign up is: https://us06web.zoom.us/meeting/register/hijg24mPRK69uGC0gUq8zw

The Opportunity

Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session.

An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact.

Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

Please direct any questions to [email protected]

Satellite Shorts from All Over

+ As of this writing, 4 complete AMSAT CubeSatSim Kits are still available for purchase from the AMSAT store. This kit allows you to build a CubeSat Simulator with no soldering, just assembly. CubeSatSim is a low-cost satellite emulator that runs on solar panels and batteries, transmits UHF radio telemetry, has a 3D printed frame, and can be extended by additional sensors and modules. It is perfect for the classroom or for public demonstrations. The kit can be purchased from the AMSAT store. Sorry, shipping is only available to U.S. addresses. (ANS thanks AMSAT Education for the above information)

+ AMSAT-EA’s latest PocketQube, HADES-SA (aka SpinnyOne) has been coordinated by the IARU. A 1.5 PocketQube. HADES-SA / SpinnyONE is a satellite operated by AMSAT-EA members to promote the use of CODEC2 voice and SSDV in satellite communications, both of which are open protocols. As secondary objectives, the satellite is also intended to test its Doppler-resistant modem and a new antenna deployment mechanism. The satellite includes a BBS that allows amateurs to send text messages and, optionally, upload CODEC2 recordings for transmission by the satellite. A sample CODEC2 transmission has been pre-recorded in Flash memory until new transmissions from Earth arrive. HADES-SA / SpinnyONE includes a digital camera provided (along with its dedicated software) by the UK-based company Spinning Around. The camera will capture images of the deployment mechanism —which contains a small commemorative plaque— as well as whatever lies within its field of view at that moment. Every three days, a new picture will be taken and transmitted to the ground using the SSDV protocol. Image transmissions will occur continuously every few minutes so that stations worldwide can receive the frames. In the event of a camera failure, an internally stored image will be transmitted instead. Tools and detailed instructions on how to use them will be published on the AMSAT-EA website at https://www.amsat-ea.org/proyectos. The satellite is scheduled to launch on the SpaceX Transporter-16 mission approximately March 14, 2026. (ANS thanks AMSAT-EA and the IARU for the information)

+ NASA’s SpaceX Crew-11 mission safely splashed down early Thursday morning in the Pacific Ocean off the coast of San Diego, concluding a more than five-month mission aboard the International Space Station. Crew-11 returned home about a month earlier than planned because of a medical concern teams are monitoring with one of the crew members, who remains stable. (ANS thanks NASA for the information)

+ If everything has gone to plan, the rollout of NASA’s Space Launch System rocket and Orion spacecraft for the Artemis II mission around the moon commenced about 12 hours prior to publication (Saturday, January 17th at 7:00am EST). The Artemis II launch window opens as early as February 6th. (ANS thanks NASA for the information)

+ NASA, along with the U.S. Department of Energy (DOE), announced on Tuesday, January 13th a renewed commitment to their longstanding partnership to support the research and development of a fission surface power system for use on the Moon under the Artemis campaign and future NASA missions to Mars.

W2RS Memorial AMSAT CW Activity Day to be Held January 1, 2026

In March 2022, the AMSAT community lost one of our pioneers when Ray Soifer, W2RS, became a silent key. In addition to his numerous contributions to AMSAT and the worldwide amateur satellite community, Ray was also the long time organizer of AMSAT’s CW Activity Day – previously AMSAT Straight Key Night – held in conjunction with the ARRL’s event on New Year’s Day. In recognition of Ray’s long time service to AMSAT and his keen interest in CW operating via satellite, AMSAT’s CW Activity Day is now known as the W2RS Memorial AMSAT CW Activity Day.

Ray Soifer, W2RS (SK)

The rules are simple – operate CW through any amateur satellite between 0000 UTC and 2359 UTC on January 1, 2026. Straight keys and bugs are encouraged, but not required. Logs are not required, but operators are encouraged to submit a report of their activity to the AMSAT-BB. Photos and video clips of activity are also encouraged – post them on X or other social media networks and tag @AMSAT or #amsat.

Remember to use the minimum power required for communication as constant carrier modes, including CW, can disrupt transponder operation for other users.

New Satellite Tracking Application Released

Bob McGwier, N4HY, has announced the release of a new satellite tracking application entitled Visible Ephemeris.

Visible Ephemeris is a modern, spiritual successor to Quiktrak (1986), re-engineered for the Raspberry Pi 5 and modern silicon. It is capable of propagating 13,000+ satellites in real-time with sub-second updates while maintaining <5% CPU utilization.

Visible Ephemeris is high performance physics based program using Kelso/Villado SGP4, to track satellites (all in the Celestrak TLE). It uses McGwier’s implementation of Pedro Escobal AOS/LOS search but rewritten for altitude and not Eccentric Anomaly. The code is designed for and intended for Raspberry Pi and displays graphics components using Web UI.

It features a Hybrid Decoupled Architecture where the UI, Orbital Mechanics, and Network Services run on independent threads, ensuring the interface never freezes—even during heavy calculation loads.

Visible Ephemeris has been released under the MIT license and further details can be found at https://github.com/n4hy/VisibleEphemerisCPP.git

How University Space Clubs Prepare for Their First Satellite Project

The spark of curiosity and ambition often starts in a university lab: a handful of students gather, sketch rough diagrams on whiteboards, debate orbital mechanics at midnight, and dream of seeing their own hardware flying above Earth. For many of these aspiring engineers and scientists, involvement with a student satellite club represents more than just coursework: it’s their first real shot at participating in space exploration. These clubs, across universities worldwide, transform ideas into hardware and enthusiasm into the kind of rigorous planning it takes to actually launch.

From Idea to Kickoff: Forming the Team And Setting Goals

At the outset, a group of students (often from different disciplines like mechanical engineering, computer science, electronics, or physics) comes together with a shared interest in building a satellite. For many, this marks the beginning of a university satellite project rather than just a class exercise, and some teams even use a dedicated research assistant to streamline early planning and gather technical insights. The club defines its mission: maybe it’s Earth observation, environmental sensing, communications testing, or a technology demonstration.

The first practical step is to assemble a core team: subsystem leads for avionics, communications, structure, power, payload, and operations. This division, common in professional aerospace teams, helps students learn early how complex spacecraft are divided into interdependent systems. Some clubs also look for faculty advisors or collaborators from industry to guide them through unfamiliar territory.

Once the pieces are in place, the club sets goals and schedules. Will this be a CubeSat, a smaller PocketQube, or a microsatellite? What payload makes sense given the budget and skills available? How will ground station communications work? Early decisions help steer the entire project and establish realistic expectations about scope, cost, and timeline.

The Importance of Design, Simulation, And Prototyping

Design is where theory meets reality. Students work on 3D models of satellite structure, layout of solar panels, shielding, antennas, and internal boards. They simulate thermal, electrical, and mechanical stresses to ensure their satellite can survive launch vibrations and the harsh environment of space. Many clubs employ computer-aided design (CAD) tools and simulation software to anticipate potential issues.

Prototyping follows design. Groups build mock-ups or engineering models — sometimes out of inexpensive materials — to test fits, deployment mechanics, and subsystem integration. This hands-on phase reveals assembly challenges that might not show up on the screen. It also builds critical skills: soldering, wiring, 3D printing parts, basic clean-room assembly practices, and rigorous testing.

Building Support Networks: Mentors, Funding, Partnerships

A student group rarely operates in isolation. Universities might provide lab space, clean rooms, testing facilities, and occasionally small budgets, but often, additional external support is crucial. Clubs frequently reach out to faculty in engineering, physics, or computer science departments for mentorship. Some clubs also form partnerships with research institutions, local aerospace companies, amateur radio communities, or national space agencies to gain access to more advanced equipment.

Ground-Station Planning And Mission Operations Prep

One often-overlooked but essential component is the ground segment. A successful satellite needs to reliably communicate with Earth: upload commands, receive telemetry, downlink data. For many student teams, building or adapting a ground station is part of the learning curve.

On the operations side, the team writes procedures and schedules: when to turn on instruments, how to run health checks, how to handle contingencies like partial failures or unexpected behavior in orbit. This mission-operations mindset trains students in the discipline of space mission management.

Preparing for Launch: Testing, Regulatory Paperwork, And Final Review

As the launch nears, the club shifts into full production mode. All subsystems must be assembled, tested, and integrated. Thermal-vacuum tests, vibration tests, and electromagnetic interference tests help ensure the satellite will survive the rigors of launch and space. Students often run repeated functional tests: power cycling, communications tests, antenna deployment, battery charging, and simulating real in-orbit operations.

At the same time, they must deal with paperwork: launch licensing, radio-frequency licensing, compliance with local and international space regulations, and environmental reviews. Some universities facilitate this, but others require the student club to navigate the regulatory process itself, a valuable learning experience in project management.

Once everything checks out, the team must coordinate with a launch provider, reserve a ride-share slot or secure a deployment contract, define orbit parameters, and prepare payload manifests.

The First Launch, And What Comes Next

Reaching orbit is a major milestone, but for student-built satellites, it’s only the beginning. First missions are typically demonstration or technology-testing. Once the satellite is in orbit, the ground station begins routine operations: receiving telemetry, validating system health, operating payloads, and collecting data.

Why do these clubs matter? Beyond the immediate technical achievement, they cultivate a culture of innovation, hands-on learning, and collaboration. They lower the barrier to entry into space for students who might never have had the opportunity otherwise. Many graduates of student satellite clubs go on to careers in aerospace, research, or related industries, carrying with them practical skills in design, systems engineering, hardware testing, and project management.

As university clubs gain experience and build reputations, they do more than just offer small satellite development for students; they also help governments and space agencies recognize the value of small satellites: low-cost experimentation, rapid iteration, educational outreach, and workforce development.

Happy 12th Birthday to AO-73 (FUNcube-1)

AO-73 celebrated its 12th birthday on November 21, 2025. The satellite is still operating well in full-time transponder mode.

On November 21, 2013 FUNcube-1 (AO-73) was launched from the Yasny launch base located in the Orenburg Region, Russia on a Dnepr Launch Vehicle into a 600 km, 97.8º inclination sun-synchronous orbit. In this orbit the satellite passes over the British Isles and Europe approximately 3 times in the morning, and 3 in the evening, every day, perhaps allowing the morning passes to be used for educational purposes and the evening passes for Amateur Radio communications.

FUNcube carries a UHF to VHF linear transponder that has 300 mW PEP output and which can be used by Radio Amateurs worldwide for SSB and CW communications.

Communication subsystem:
• 145.935 MHz BPSK Telemetry 30/300 mW
• Inverting SSB/CW transponder 300 mW
– 435.150 – 435.130 MHz Uplink
– 145.950 – 145.970 MHz Downlink

The passband may be up to 15 kHz higher depending on on-board temperatures. Low temperatures give higher frequencies

As of writing, ground stations from around the world have collected 11,631,536 frames of telemetry throughout the satellite’s life. The satellite’s recently received telemetry values can be found on AMSAT-UK’s Data Warehouse at http://data.amsat-uk.org/ui/fc1-fm.

Successful Reception of CatSat 10 GHz Downlink

Mike Seguin, N1JEz, reports the successful reception of the University of Arizona’s CatSat’s 10 GHz downlink on 10.47 GHz on the morning of November 21, 2025. The satellite’s  linear transponder uses 10 GHz down and 5 GHz up. More information is available at https://catsat.arizona.edu/

Mike reports that signals were quite good in FN34xn in Vermont! His next step is to try the uplink on 5 GHz on 5.663 GHz.

Below is a link to a portion of the pass. It is an I&Q file recorded with HDSDR using the Winrad format.

Congrats to the CatSat team!!

SO-124 Nears End of Orbital Life

Simulations indicate that the decay of our satellite HADES-R (SO124) is approaching and will likely occur during the first two weeks of January 2026. If you can, take the opportunity to make use of this satellite, which has been working very well and has brought much joy to radio amateurs around the world. Any old FM equipment will work, since the repeater is level-activated and does not require a sub-tone.

The frequencies and operating modes are as follows:

SO-124

145.925 MHz uplink, Modes: FM voice (no sub-tone) and FSK 200 bps, AFSK, AX.25, APRS 1200 / 2400 bps
436.888 MHz downlink,  Modes: FM voice, CW, FSK 200–2400 bps

Changes to AMSAT TLE Distribution for November 21, 2025

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/.

This week there are no changes to the AMSAT TLE Distributions.

ARISS News

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.

Scheduled Contacts

Istituto Di Istruzione Superiore “Il Tagliamento” Di Spilimbergo (Pn), Spilimbergo, Italy, telebridge via IK1SLD

AND

Istituto Comprensivo “G. Mazzini”, Livorno, Italy, telebridge via TBD

The ISS callsign is presently scheduled to be OR4ISS
The scheduled crewmember is Zena Cardman KJ5CMN
The ARISS mentor is IZ2GOJ

Contact is go for: Fri 2025-11-28 11:40:17 UTC 34 deg

Due to the scheduled docking of the Soyuz scheduled for Thu 2025-11-27 12:38 UTC, the radios will be powered down.  Here is the schedule for power down and power up:

Service module radio power down Thu 2025-11-27 10:35 to 10:40 UTC

Columbus module radio power down Thu 2025-11-27 10:40 to 10:45 UTC

Service module radio power up Fri 2025-11-28 10:15 to 10:20 UTC

Columbus module radio power up Fri 2025-11-28 10:20 to 10:25 UTC

Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication.  You can always check https://live.ariss.org/ to see if a school is Livestreaming.

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

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down),  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.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html

AMSAT Ambassador Activities

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.

Satellite Shorts from All Over

+ China is set to launch an uncrewed Shenzhou spacecraft to the Tiangong space station to provide the Shenzhou-21 astronauts with a means of returning home. An airspace closure notice issued Nov. 17 indicates that China is preparing the Shenzhou-22 spacecraft and a Long March 2F rocket for launch at around 04:10z. on Nov. 25. (ANS thanks SpaceNews Weekly for the above information)

+ Reports indicate the Lobachevsky (RS83S) will be launched in late December. Although the IARU coordination request indicated that it would carry a digital repeater, the satellite’s website indicates that it carries an FM transponder with a 70cm uplink and a 2m downlink. (ANS thanks SpacePi and PV8DX for the information)
