THE SBS TT&C SYSTEM

International Telemetering Conference Proceedings / October 13-15, 1981 / Bahia Hotel, San Diego, CaliforniaThe SBS Telemetry, Tracking and Command (TT&C) System consists of one earth station in Castle Rock, Colorado and a combined earth station and control center in Clarksburg, Maryland. The system commenced operation with the launch of the SBS-1 spacecraft in November 1980, two and one-half years after the initiation of the design study. The system design utilized as a base the experience of COMSAT and SBS personnel on the INTELSAT and COMSAT General networks. From this base, a system was designed around real-time telemetry processing for four spacecraft that included such features as: subsystem oriented spacecraft displays, centralized control over the hardware and software at both sites, human factors orientation and ease of future expansion. The major functions performed include: spacecraft commanding, ranging, orbit and attitude determination, telemetry retrieval and analysis and comprehensive monitoring and alarm system.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
