AbstractThe Tracking and Data Relay Satellite System (TDRSS) will provide communications and tracking services to the Space Shuttle and most other NASA missions of the 1980's. Relay services are provided between NASA's near earth satellites and a ground terminal at White Sands, N.M. via synchronous Tracking and Data Relay Satellites. Establishing and maintaining the communications links is a complex task which includes spatial, signal and data acquisition involving crosslinks between the TDRS and NASA's user satellites. Concepts and capabilities are presented for antenna acquisition, and for PN code and carrier acquisition. Total acquisition times, including bit synchronizer and decoder acquisition are also provided.
