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 …

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.
