For my undergraduate dissertation I undertook a group project to design a small satellite power supply. The deliverable product was a populated and tested PCB designed to fit the demanding physical constraints imposed by the satellite. The main features of the power supply include solar energy harvesting and battery monitoring along with six individual supply lines, each complete with monitoring and protection. The project also involved a lot of background research into cosmic effects on electronics.
I took the lead PCB design role and was responsible for physical design, component choice, layout, and thermal management. The final product passed rigorous electrical, vibrational and thermal testing and is awaiting deployment into space as part of the University of Southampton Small Satellite Project (at time of writing, September 2016).
