NASA has developed an experimental flight payload, the Space Communication and Navigation (SCaN) Testbed, to investigate software defined radio (SDR) communications, networking, and navigation technologies, and is operational in the space environment. The payload consists of three software defined radios each compliant to NASA’s Space Telecommunications Radio System Architecture, a common architecture standard for space software defined radios. These software defined radios are new technology developments for NASA and industry partners. Launched in July 2012, the payload is externally mounted to the International Space Station truss for conducting experiments representative of future mission capability. Experiment operations will include in-flight reconfiguration of the SDR waveform functions and payload networking software. The flight system will communicate with NASA’s orbiting satellite relay network, the Tracking and Data Relay Satellite System (TDRSS) at both S-band and Ka-band and direct to the ground to any Earth-based compatible S-band ground station. The system will be available for experiments by industry, academia, and other government agencies to participate in the technology assessments and standards advancements. This paper focuses on software lessons learned through development, integration and testing as related to the avionics processor system, and the software required to command, control, monitor, and interact with the SDRs, as well as the other communication payload elements.
