ABSTRACT:
A system for compensating for varying attenuation of an uplink signal from a local node to a satellite. The system monitors two beacon signals and the local downlink signal to determine fade. An error signal, indicating the uplink fade, is generated and utilized to adjust the gain of the uplink transmitter to compensate for the fade.
