Headline Details: SAMWISE is a 2U technology demonstration mission aimed to prove several key technologies necessary for SSI?s satellites to host scientific payloads in the future. These include a magnetorquer-based ADCS, high quality cameras, S-band telecommunication, and novel deployable structures. The primary objective of the mission is to capture and downlink images using an earth-facing camera which can be pointed to observe specific targets and a boom-mounted ?selfie? camera. The SAMWISE is an amateur mission. This project is entirely undergraduate student initiated and developed. Additionally, most of the students involved either have HAM radio licenses or are studying for HAM radio licenses. Amateur radio enthusiasts around the world will be able to participate by sending commands to the satellite and receiving images in response, and by making range measurements with the satellite and performing their own orbit determination of the satellite. Proposing a UHF downlink with 125k / 500k X1 DCN telemetry and S band with 500k / 2M downlink for image and two way ranging. All modulation information will be published on the SSI Github, https://github.com/stanford-ssi Planning a SpaceX launch in Q4 2023 into a 525 km SSO. More info from ssi.stanford.edu
