This project aims to utilize a Basilisk simulation to generate sun vector and eclipse data for testing satellite hardware on a solar simulator. The simulation is built by parsing a TLE (Two Line Element) data set with the Basilisk module, which allows us to figure out position and velocity vectors for the satellite. Using these vectors and the TLE data set, we are able to build the orbit of the satellite as well as how fast the satellite is moving within that orbit. Now with the simulation and orbit established, we can determine whether the satellite is in the sun or not, as well as identify which of the 6 sides of the satellite is in the sun at a given time. With this new eclipse and sun vector data generated, we can send the data via serial to a raspberry pi pico that runs our solar simulator for solar panel testing applications.
