ABSTRACT:
A beacon signal is radiated from both the communications antenna and from a separate beacon antenna, the latter having a broader radiation pattern than the communications antenna pattern and overlapping the communications antenna pattern. The radiated signals are sensed at ground stations located about the periphery of a desired communications antenna radiation pattern coverage area on earth to provide sensor signals proportional to the ratios of the amplitudes of the two signals. The sensor signals are compared with one another to provide an error signal indicative of any departure of the communications antenna pattern from said desired coverage area. A control system in the satellite is responsive to this error signal for maintaining the communications antenna radiation pattern directed to the desired coverage area on earth as, for example, by controlling the attitude of the satellite.
