Electrical Power System For An Open Hardware Cubesat, Sofiane Chaieb, Michael Wegerson, Jeremy Straub, Ronald Marsh, David Whalen

Jeremy Straub

The OpenOrbiter program is developing a complete set of CubeSat hardware and software to facilitate the development of a 1-U CubeSat (10 cm x 10 cm x 10 cm, 1.33 kg spacecraft) with a parts cost of less than $5,000. This poster covers the electrical power system (EPS) for that spacecraft. The EPS is an assemblage of components that supplies all spacecraft subsystems with power, while performing health assessment of the battery and electrical buses. The EPS has a crucial role in the spacecraft and thus has to be developed and tested with extreme care.

The EPS generates power using …

Advancement Of The Software Defined Radio (Sdr) For The Open Orbiter Project, Michael Wegerson, Jeremy Straub, Sima Noghanian, Ronald Marsh

Jeremy Straub

Software Defined Radios (SDRs) are an exciting development in radio technology. The SDR uses software to perform many of the tasks that only hardware could previously complete on a traditional analog radio. Such tasks include encoding/decoding or applying filters to reduce noise on the signal. This powerful fusion of software and hardware have allowed SDR to be smaller in size and have a greater functionality than traditional radio setups; a perfect solution for our Open Orbiter satellite. Currently, the implementation we use consists of a simple $20 USB TV decoder for receiving, a Raspberry Pi micro-computer for transmission, and the …
