Computer simulation of TDRSS autotracking
Abstract
The Tracking and Data Relay Satellite System (TDRSS) consists of synchronous-orbit satellites and a single ground station at White Sands, NM. Each TDRSS satellite has two 16-foot dish antennas with dual-frequency feeds for transmission and reception at S- and Ku-band. Autotracking is required on the Ku-band return link from user spacecraft. The TDRSS autotrack system was verified by computer simulation rather than by end-to-end hardware testing. One of the simulation models is described. Attention is given to an overview of system operation, a computer model description, and the simulation results. An example plot shows the sensitivity of system pointing error to user incidental amplitude modulation frequency.
