SleeperSat-1
SleeperSat-1 Mission
The Aerospace Center's SleeperSat-1 is an educational initiative that supports students in learning about the design, construction, and operation of small satellites. The SleeperSat-1 project includes two payload modules: an artificial intelligence/machine learning (AI/ML) module and a robotic arm module. The AI/ML module aims to demonstrate machine learning using commercial-off-the-shelf (COTS) components in low Earth orbit. The robotic arm module will study the effects of induced disturbances caused by operating a robotic arm in a microgravity environment within a CubeSat platform.
Communications Overview
The communications subsystem facilitates the satellite's communication from space to the ground and vice versa using radio frequencies. Different frequencies allow for varying transmission rates, determining how much information can be relayed within a given timeframe.
The SleeperSat-1 mission primarily uses S-Band for communication, handling both the reception of commands from Earth and the transmission of telemetry and video data critical to our science objectives. The project uses UHF for beaconing and to serve as a secondary communication channel.
