| Headline Details: HADES-ICM 1.5 PQ satellite main mission is to act as a FM voice repeater. It can also repeat FSK derived modes like FT-4 and FT-8. As there is a small empty space available, it will be used to carry an experiment by Smart IR/Graphene Engineering Innovation Centre, GEIC University of Manchester (UK) consisting in a very low power active radiator to be tested on space conditions. The data for this experiment will be transmitted in a specific data packet in the telemetry. This experiment is the same as the one in HADES-R. This experiment will be delivered to AMSAT EA for integration and will be operated by AMSAT-EA, being all its data public and open. Engineering and manufacturing support for this mission is carried out with the help of private sector companies and universities, but AMSAT-EA will be the only operating organization. icMercury is a company also supporting the mission. It will develop ground tracking software for the satellite. Telemetry will send some FSK English formatted text messages, part of a history, to be collected as a challenge. HADES-ICM will offer licensed radio-amateur around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. FSK derived transmissions and modes like FT-4 and FT-8 are also supported. As an improvement from previous missions, maximum power is now 0.25W when battery is charged (the amplifier uses battery energy), allowing easier QSOs with handheld antennas like Arrow or Elk and less sensitive receivers. The satellite will also transmit telemetry with its status and CW messages. This all will be achieved by implementing a SDR based repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a subtone. As payload, the satellite will carry an experiment by Smart IR/Graphene Engineering Innovation Centre, GEIC University of Manchester (UK) consisting in a very low power active radiator to be tested on space conditions. This experiment is the same as the one in HADES-R satellite with updates and improvements. Also, as a challenge made with icMercury, telemetry will send FSK English formatted text messages, part of a history, to be collected. Launch is expected for February 2025 in SpaceX Transporter-13 mission managed by the space broker Alba Orbital / D-Orbit. The main mission for the satellite is to act as a FM voice repeater although due to its SDR nature it can repeat data too. Users will have the capability of making voice contacts and use FSK derived modes like FT-4 and FT-8. This satellite is based on the hardware of HADES-D (SO-121, currently being used by HAMs worldwide for voice contacts) and the next to launch HADES-R. FM satellites are very demanded and appreciated by the HAM community because they are easy to use, they don’t require of expensive transceivers and allow continental and even transatlantic contacts in some conditions. With this satellite we also put into use the amateur VHF and UHF satellite sub-bands helping to secure them for the community in the future. Proposing a UHF downlink and planning a launch on SpaceX Transporter 13 into a 500-600 km polar orbit in Feb 2025. **A downlink on 436.666 MHz has been coordinated** | ||||
