A B S T R A C T A satellite locating system for use in a satellite communication system having a transmitting station in which radio signals with signal identification data is transmitted via a satellite to a receiving station. The receiving station includes an antenna for receiving radio signals relayed by the satellite, a detector circuit located near the antenna for detecting the received signals, a signal processing circuit located remotely from the antenna for processing signals received from the detector circuit, a power supply for producing electrical power, a cable for carrying the power from the power supply to the detector circuit and for carrying received radio signals from the detector circuit to the signal processing circuit, a modulator for causing the voltage level of the output power from the power supply to fluctuate in response to a first control signal and to increase or decrease in response to the level of a second control signal, and an energy level detector couplable to the processing circuit for producing a signal which indicates the energy level of the received radio signals. Also included is a microprocessor coupled to the signal processing circuit and the energy level detector for processing received radio signals and the signal identification data, and for supplying the first control signal to the modulator when the correct signal identification data is received and for supplying the second control signal to the modulator at a level corresponding to the energy level of the received radio signals. The system also includes a portable transducer which may be connected into the cable adjacent the detector circuit for receiving the modulated output power and for producing an audible signal whose frequency is determined by the voltage level of the output power.
