Researchers at NASA’s Marshall Space Flight Center have developed software-defined radio (SDR) telemetry transceiver technology to collect and transmit data to and from small satellites and microsatellites. The SDR concept uses a minimal number of traditional analog radio-frequency components to convert RF signals to a digital format. Digital signal processing replaces bulky radio-frequency components, and enables reduced cost as well as size, weight, and power requirements (SWaP). The NASA technology enables software and firmware updates that increase the lifespan and efficacy of satellites, supporting a wide variety of changing radio protocols as they are developed. A modular design enables inclusion of multiple band frequency transmitters and receivers (S-band, X-band, Ka-band, etc.). The NASA SDR can find use in satellite applications in which cost savings, upgradability, and reliability are essential. A first-generation SDR has been flight tested on NASA’s FASTSAT mission.
