ABSTRACT:
Even when a multi-spot beam is utilized, a demand assignment multiple access (DAMA) type satellite communication can be established between a plurality of satellite earth stations installed in one zone located opposite to another zone where a control station is installed, and between the control station and the satellite earth station installed in the same zone. The control station transmits a channel setting signal for setting a communication channel to the satellite earth stations installed in the opposite zones by using a CSC signal, and further sets a channel of a transmitting/receiving unit in such a manner that after the CSC signal derived from the satellite earth station has been received, this CSC signal is returned thereto. A repeater station has a function such that repeater station receives the CSC signal to return this CSC signal, and also receives a communication signal to return this communication signal. The satellite earth station includes a delay device for setting a time defined as after the CSC signal is received, until a response signal is transmitted, based on the received delay data.
