Project Lead: Vishhal Kumar

Main Objective: Develop the system architecture and complete PCB layout focusing on Hardware in the Loop (HIL) testing, to simulate CAN-based communication between the OBC and the EPS. The board will represent the EPS, providing onboard visualization of power rail states, include EPS fault logic, and ability to charge / discharge a battery, more so focusing on the ability to transition the satellite between modes. We’re seeking to understand how the NanoPower P80 (COTS EPS) responds to spacecraft mode transitions after being commanded by the CAN BUS, and how these commands are translated to turning on/off corresponding voltage rails.

Goal: Utilize the HIL testing PCB, to develop preliminary software for spacecraft mode transitions. For members of NSL, it would be great to provide industry experience with PCB design, component selection, and a understanding of how the EPS works all the way from the electrical aspect to the software with watchdogs and inhibits
