The Polarization-modUlated Laser Satellite Experiment (PULSE-A) is the University of Chicago’s student-led mission to demonstrate an optical downlink at a data rate of 1 to 10 Mbps using circular polarization shift keying (CPolSK). PULSE-A comprises a 3U CubeSat bus carrying a < 1.5U optical transmission terminal and a dual optical-RF ground station. The ground station (GS) system consists of the optical ground station (OGS) and the RF ground station (RFGS). The RFGS is responsible for standard communications and control tasks, while the experimental OGS receives the optical transmission from the satellite’s payload.

To perform satellite-to-ground optical communications, the OGS needs to track, receive, and decode the transmitted signal while providing its own beacon, which allows the satellite to track the OGS. These requirements are accomplished by four assemblies within the OGS: tracking, polarization state preparation, signal decoding, and beacon. The tracking assembly collects, condenses, and collimates incoming laser light from the …

Toward Trusted Onboard Ai: Advancing Small Satellite Operations Using Reinforcement Learning, Cannon Whitney, Joseph Melville

Small Satellite Conference

A Reinforcement Learning (RL) algorithm was developed for command automation onboard a 3U CubeSat. This effort focused on the implementation of macro Control Action Reinforcement Learning (CARL), a technique in which an onboard agent is provided with compiled information based on live telemetry as its observation. The agent uses this information to produce high-level actions, such as adjusting attitude to solar pointing, which are then translated into control algorithms and executed through lower-level instructions. Once trust in the onboard agent is established, real-time environmental information can be leveraged for faster response times and reduced reliance on ground control. The approach …
