FIELD: satellite communication systems. SUBSTANCE: system and method are proposed for controlling power of shared-resource signal transmitted by satellite repeater in satellite communication system. System has gateway-station for transmitting communication signals including shared-resource signal, satellite repeater for signal transmission to at least one subscriber's facility such as telephone set, and at least one subscriber's facility for signal reception. Method involves shared- resource signal reception by each subscriber's facility through satellite repeater, measurement of signal power in each subscriber's facility for shared-resource signal received, transmission of data on signal power to gateway, and power control of shared-resource signal transmitted by satellite repeater basing on signal power. EFFECT: enhanced reliability of shared-resource signal power control. 6 cl, 4 dwg
