NEXT GENERATION TDRSS MA BEAMFORMING SUBSYSTEM

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, CaliforniaThe Tracking and Data Relay Satellite System (TDRSS) Multiple Access (MA) Return Service provides a communication path that originates at a customer platform (either a spacecraft or other type of emitter) and is routed through a geosynchronous Tracking and Data Relay Satellite (TDRS) back to a customer control center or data acquisition location. Conventional operations provide Space Network (SN) customers with MA Service based on a schedule generated from user requests. The MA Service currently provides return link telemetry services to customer platforms with real-time, playback, and science data rates up to 100 kbps. This paper describes an integrated approach, using state-of-the-art technology and fault-tolerant architecture, to develop the next generation of TDRSS MA beamforming equipment. New designs will result in significant reduction in beamformer size and cost by at least an order of magnitude relative to the current MA equipment. This new equipment will provide the potential for increased usage of TDRSS MA services. The paper describes the in-development Demand Access (DA) Return Service that provides a new class of service using next generation technology.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
