Headline Details: PROVES Atlas is one of five satellites in the joint The PROVES Project CubeSat mission. The Pleiades Rapid Orbital Verification Experiment System PROVES Project is an extension of the Pleiades CubeSat Cluster, an inter university initiative aimed at testing open-source CubeSat architectures, promoting low cost CubeSats for educational access to space, and creating infrastructure that enhances access and interest in the radio art through satellite communications. The other CubeSats are Taygeta, Alcyone, Miaia and Electra. PROVES Atlas is a 1U CubeSat with the following functions. 1. Provide digital packet relay services in both UHF and S-Band to the amateur radio community as a primary mission. 2. Allow amateur operators route packets to other satellites in the PROVES cluster to be repeated. 3. Employ a student-built attitude determination and control system payload that employs magnetorquers and a novel flight processor unit. All of the satellites participating in The PROVES Project mission will offer digital packet relay services to the amateur radio community as a primary mission. Whenever possible, radio amateurs will also be invited to attempt to route packets between the satellites using our open source DRIFT (Dynamic Relay for Intersatellite Fault Tolerance) protocol, published on our website. We will also publish the open source design of the PROVES Ground Station Kit. This design describes the essential hardware and software required for an amateur operator to construct a ground station capable of downlink and uplink to the PROVES satellites via UHF. PROVES - Atlas will attempt to engage and educate students and radio amateurs around the world with an understanding of the impact of space mission geometry on radio communications through its onboard attitude determination system. By making attitude information available to amateurs contacting the satellite, the radio operators can experiment with optimal orientations and timings for ideal link performance. Proposing a VHF downlink for APRS and a UHF downlink using LoRa with dynamic data rates between 250bps and 300kbps. Additionally n S-Band downlink of image data using 2Mbps FSK and an experiment in compact amateur radio mobile relay services using an auxiliary LoRa link on the S-Band radio at 467 bits/sec.
