Software-Defined Radio for Space-to-Space Communications

A paper describes the Space- to-Space Communications System (SSCS) Software-Defined Radio (SDR) research project to determine the most appropriate method for creating flexible and reconfigurable radios to implement wireless communications channels for space vehicles so that fewer radios are required, and commonality in hardware and software architecture can be leveraged for future missions. The ability to reconfigure the SDR through software enables one radio platform to be reconfigured to interoperate with many different waveforms. This means a reduction in the number of physical radio platforms necessary to support a space mission’s communication requirements, thus decreasing the total size, weight, and power needed for a mission.
