ABSTRACT:
A method and system for determining an actual location of a sense antenna associated with a phased array communications satellite. A plurality of calibration carrier signals are transmitted at known frequencies. Each of the plurality of calibration carrier signals are received at a second frequency and compared with each of the plurality of transmitted calibration carrier signals. The actual location of the sense antenna is determined based on the comparison between the known frequency and the second frequency. The phased array communications satellite then broadcasts communication signals based on the actual location of the sense antenna rather than a desired location of the sense antenna.
