Headline Details: A 2p PocketQube mission. The FossaSat-2B continues with the functionality of the amateur FOSSASAT-1, 1B and 2 amateur satellite, it will be launched into a LEO orbit with a short orbital life. The following points are our objectives for the mission: The first is the general development of miniaturized and inexpensive satellite systems for space applications using off the shelf components. As amateurs, it is a huge step forward for our nation being able to prove that we can successfully design, manufacture & deploy a satellite in orbit for amateur investigation and use with a limited budget. An ADCS system developed by students at the Rey Juan Carlos University will be used for antenna pointing of the satellite and give students opportunities to test their software in space. As a continuation of the FossaSat-2 and 1B mission which will deorbit approximately at the same time as this satellite will launch, we hope to extend the lora coverage on the same frequency an additional 2 months. The output power from the transmitter required for the correct reception during a pass is also very low at well under 100mW, being spread spectrum at such low power it poses no interference risk. It operates at a considerable level below the noise level of other systems and would cause no interference to weak narrowband signals. Amateurs will be able to repeat messages on the satellite, store and forward messages openly across the globe. Hundreds of amateur ground stations are registered and interested in the use of this digital repeater. Students & Amateurs will be able to receive telemetry from the satellite with inexpensive hardware, expanding & promoting the amateur satellite community in the youth. Lastly the satellite will carry an experimental amateur thruster similar to the one tested in collaboration with the GENESIS-N /L satellites Uplink challenges will also be carried out as done with FOSSASAT-1 with rewards for amateurs. All we do is completely open source, all information regarding the design of the satellite & how to decode its information will be clearly laid out & hosted by us, promoting its use. Proposing a UHF downlink with CW, 9k6 GFSK and Lora 125kHz Chirp. Planning a SpaceX launch into a 450km SSO in Q1 2021. **Further information has been requested from the group** **The IARU coordination panel have subsequently responded that "Fossa in our view is a commercial entity and commercial satellites don’t belong in amateur spectrum"**
