ABSTRACT:
Radiated from each orbiting satellite of a satellite communication network to M cells (M representing an integer, such as thirty-seven) covered with a predetermined solid angle on the earth, M spot beams are identified by M identification codes. In an earth station which may be a portable unit, a burst signal transmitter device (31) comprises a receiver part (35) receiving one of the spot beams as a received beam at a reception time, to recognize as a recognized code one of the identification codes that identifies the received beam, and a transmitter part (45) for transmitting burst signals at a transmission time delayed from the reception time by an offset amount selected by the recognized code from M offset amounts predetermined for the identification codes. Preferably, the M offset amounts are stored in a memory (43).
