OpenOrbiter is a student project at the University of North Dakota to design and build a low cost1 and open-hardware / open-source software CubeSat2. The Ground Station is the user interface for operators of the satellite. The ground station software must manage spacecraft communications, track its orbital location , manage task assignment, provide security and retrieve the data from the spacecraft. This will be presented via a graphical user interface that allows a user to easily perform these tasks.

A Software Defined Radio (SDR) will be used for OpenOrbit-er satellite to ground communications. The use of SDR al-lows for a smaller, more versatile radio then what a stand-ard hardware radio can provide; perfect for the unpredicta-ble environment Open Orbiter will be exposed to. Current implementation uses a simple $20 USB TV decoder for the receiver and the open-source program GNU Radio for soft-ware decoding. Broadband FM transmissions have been re-ceived and decoded successfully and on-going experimen-tation for receiving satellite communications are yielding promising results.
