Over this last summer, I worked on multiple projects related to the electrical systems on Portland State Aerospace Society’s next satellites OreSat0.5 and OreSat1 and on related ground support equipment. Most of my time was spent working on the Battery Testing system and the University Class Open Ground Station (UniClOGS) power delivery system, as well as fixes and rework to several other satellite systems. The Battery Testing System is used to ensure that the Lithium Ion cells we use on the satellite meet their specifications and do not pose a risk of fire to the satellite, the launch vehicle, or anywhere else the satellite may be. The required tests take several weeks to complete and must be done to every potential flight cell, so an automated tester is desirable to ensure that all tests are completed and logged correctly. My job was to create the system to administer these tests on flight candidate cells. The UniCloGS Power Delivery Board (UPD) controls power to the equipment on the roof enclosure at our ground station. This board individually controls power to each of the pieces of equipment on the roof, to turn on the required equipment when the station is in use and to turn it off the rest of the time. The board also controls several inputs to other parts of the system and can reboot misbehaving equipment remotely. My job was to update the old design adding new features and using in-stock chips.
