Abstract
A TVRO earth station having a satellite seeking system comprising at least one controllable motor for adjusting the position of an antenna for receiving signals from a satellite having multiple transponders transmitting signals at prescribed nominal center frequencies and with different polarizations, control means for energizing the motor to move said antenna along a predetermined satellite-searching path, a receiver for receiving the incoming signals from the antenna and successively tuning to the center frequencies at each of a succession of intervals along the searching path, means responsive to the signals detected by the receiver for producing a signal or value representing the quality of the detected signals at each of the successive intervals along the searching path, and means responsive to the quality-representing signal or value for identifying the locations along the searching path at which the antenna receives signals from a satellite.
