Software has been developed that provides an integrated and automated test environment for the Space Telecommunications Radio System (STRS). This software package is Linux based and provides interactive and scripted control to test the JPL Software Defined Radio (SDR) implementing STRS hardware and software functionality. It also provides error checking and data logging capabilities for system diagnosis. This is a C programming language-based software that uses the host’s serial interfaces, a Ballard Technology, Inc. 1553 bus interface, and Star-Dundee SpaceWire-USB interface to communicate with the JPL SDR to issue test commands, receive telemetry, and transfer files.
This work was done by James P. Lux, Minh Lang, Kenneth J. Peters, and Harry Balian of Caltech for NASA’s Jet Propulsion Laboratory.
