SPACE SHUTTLE ORBITER PROCESSING, MONITORING, AND TELEMETRY SYSTEMS.

An overview is presented of the Space Shuttle avionics with prime emphasis on how the orbiter's on-board processing, monitoring, and telemetry systems function during the on-orbit mission phase. Included is a description of the S-band and Ku-band RF transmission link and its relationship to the ground systems, payload interfaces, and support equipment. Also discussed are the flexibility of its instrumentation system (including capability to provide formats), features of the on-board monitoring systems (dedicated displays, cathode-ray tubes, and caution and warning systems), and methods for storing and processing data (recorders, mass memory, and on-board computers). The orbiter's avionic services to the payloads and the future growth of the Space Transportation System and the orbiter are also discussed.
