Digital spacecraft antenna tracking system |
摘要 |
A digital spacecraft antenna tracking system and method are provided which utilize an array of antenna feed elements oriented relative to a shaped spacecraft reflector antenna system each of which generates an output signal corresponding to a received incident signal. The outputs can be processed by a mixer/multiplexer (M/MUX) before processing by a digital tracking control receiver. The direction of a beacon signal incident on the spacecraft reflector antenna system is obtained by the TCR by comparing the beacon response of the M/MUX to a set of premeasured responses to incident signals having a known direction or orientation relative to a reference tracking grid. The premeasured responses are stored in a memory as a set of reference responses. Once the direction of the signal is obtained, the TCR assigns control voltages which are used by the spacecraft to steer the spacecraft antenna to a desired pointing direction relative to the beacon signal.
