There's been an increase of interest in space related projects in the last year or so. With QubeCast Max being a quarter finalist in the 2014 Hackaday Prize and SatNOGS winning as well as an ever growing list on hackaday.io. As long time space fan I thought I'd add something to the efforts and decided to the design probably the most important piece of hardware in a satellite.
The Electronic Power System (EPS).
The EPS is critical to the satellite actually achieving something. Its core task is to manage the power used by the electrical systems. This typically means harvesting power from the attached solar panels, storing it and supplying it as required. Of course to do this effectively the solar energy harvesters must be highly efficient, the power must be stored with minimal waste and regulated for the other systems in the satellite with little losses.
This project will help solve the difficulties encountered when trying to design a satellite for your project!
