Tracking and Data Relay Satellite System status
Abstract
A description of the Tracking and Data Relay Satellite System (TDRSS) includes the commercial communications or Advanced Westar (AW) components and the launch, network, and test elements employed to bring the system to operational readiness for user support. With operations scheduled to commence in 1983, the TDRSS is to provide leased services to NASA for tracking and data relay of user spacecraft for a period of ten years. The TDRSS will consist of four spacecraft in orbit supported by a ground station complex at White Sands, NM. Each of the three-axis stabilized spacecraft weighs approximately 2268 kg and spans 17 meters, and will be placed in geosynchronous orbit by the Space Shuttle and the Inertial Upper Stage. Extensive C- and K-band communications capability with coverage of the U.S., Atlantic, and Pacific areas will be provided. Users and user equipment are also discussed.
