Summary	The Naval Postgraduate School is currently at work on a project to design the software for a fault tolerant Software Defined Radio (SDR) suitable for hardware (FPGAs) already on orbit. The proposed SDR will process pre-demodulated signals in order to compress the signals for potential passing to the downlink. It is presumed that the downlink does not have sufficient bandwidth to pass the entire pre-demodulated signal. SDRs are a natural fit for satellite applications because they can be changed via reprogramming after launch, thereby allowing new functionality and/or design improvement at any time in the spacecraft's lifecycle. It is expected this will make the satellite more useful over its lifespan including more operationally responsive.
