ABSTRACT:
A precision antenna pointing system and methods are disclosed. Antenna pointing error is determined by detecting RF signal phases at locations along the edge of an antenna reflector. A set of signal phase reference harnesses are used to compensate for harness induced errors. Furthermore, multiplexing is used to minimize electronics induced phase errors.
