The NASA Goddard Space Flight Center (GSFC) has created the Communications, Standards, and Technology Lab (CSTL) for the investigation, development, and demonstration of new communications standards and technologies. The testbed combines elements from the Microwave & Communications Systems Branch lab with the Flight Software Branch lab to form an end-to-end communications scenario. The testbed is currently configured to demonstrate communications, using the Internet Protocol, for the Crew Exploration Vehicle (CEV) and Lunar Surface Access Module (LSAM). The Radio Frequency (RF) systems in the CSTL are implemented using software defined radio (SDR) technology and NASA engineering model transponders. Various link layer, modulation and coding schemes have been developed and tested, including the Tracking and Data Relay Satellite System (TDRSS) spread spectrum waveforms. Flight components include mission flight software and hardware, onboard LANs, space-qualified routers, voice and video simulators. New and proposed applications and transport protocols are being tested for flight worthiness. The ground support system includes both Government-off-the-Shelf (GOTS) and Commercial-off-the-Shelf (COTS) command/telemetry equipment. This paper highlights the current capabilities of the CSTL and will present an overview of previous CSTL activities and results, as well as planned future work and opportunities.
