| Headline Details: SanskarSat-1 is a 1U amateur-radio training and technology-demonstration satellite developed by students and staff of Laxman Gyanpith, Sanskardham, together with licensed radio amateurs. Its primary mission is to provide a practical, on-orbit platform for self-training in satellite communications, telemetry, modulation, link budgets, power management and attitude control within the amateur-satellite service. The satellite carries: 1. UHF amateur telemetry beacon and experiment downlink A UHF downlink in the 435–438 MHz amateur-satellite segment continuously or periodically transmits: o Housekeeping data (bus voltages and currents, temperatures, battery state of charge, solar array status). o Basic attitude and orbit information (IMU, magnetometer, GNSS solution). o Configuration flags and experiment status. All modulation, framing and protocol details (LoRa / FSK parameters, packet formats, example decoder code) will be fully published so that any licensed amateur can receive, decode, and use the data for self-training and technical investigations. 2. Student-built optical beacon (secondary educational payload) The satellite includes a small array of high-power LEDs on the nadir panel, driven in Morse code with the amateur callsign and short identifiers. The optical beacon is only used during selected night passes and under positive power and attitude conditions. It allows students and amateurs to perform joint RF–optical experiments (e.g. correlating received RF telemetry with ground-based visual observations, verifying attitude behaviour and power-budget predictions), while still remaining entirely within the amateur-satellite mission scope. 3. Educational operations and open data The mission is operated by licensed control operators (VU32BA and associated station(s)) with active involvement of students and local amateurs. Received telemetry will be made available via an open web interface and through networks such as TinyGS and SatNOGS (where supported), giving amateurs worldwide an opportunity to contribute reception reports, decoded frames and analysis. In this way, SanskarSat-1 is not a commercial or remote-sensing mission. It is a student-run amateur-radio training satellite, with an additional optical experiment that is controlled and evaluated entirely through amateur-service telecommand and telemetry. SanskarSat-1 is inspired by Japanese student mission FITSAT-1. Proposing a UHF downlink using 4k8 FSK and LoRa at 900 bps over 125 kHz spectrum. Planning a NSIL launch from Sriharikota in 2nd week of Jan 2026 into a 505 km SSO. | ||||
