The hardware repository for our solar simulator for testing 1U solar panels Software Repo

General Information

The OreSat Solar Simulator is a benchtop simulator for hardware-in-the-loop testing of CubeSat solar modules. It uses LED and halogen light bulbs to emit light that simulates the sun's solar spectrum in low Earth orbit (Air Mass 0 or 'AM0').

The work for this was done as an MCECS Capstone Project from January to June of 2023 by Bendjy Faurestal, Adam Martinez, Cesar Ordaz-Coronel, and Charles Nasser. Andrew Greenberg was both representing PSAS as the Industry Sponsor and the Faculty Advisor to the students.

Hardware

The schematic and pcb layout were designed in kiCADv7. The boards we used were fabricated by OSHPark in Lake Oswego, OR.

The simulators are driven by a PocketBeagle Rev. A2b attached to the board.

Software

The software for this project lives in the oresat-solar-simulator-software repository.

Mechanical

The mechanical components were developed by Zeus Ayala using onShape.
