METHOD OF CONTROLLING MULTIBEAM COVERAGE OF SERVICE AREA IN SATELLITE SYSTEM USING RELAY SATELLITES ON HIGH ELLIPTICAL ORBIT Russian patent published in 2014 - IPC H04B7/185 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio communication using relay satellites on high elliptical orbits. The method includes a relay satellite establishing the angular size of the coverage area of a multibeam antenna which is not smaller than the angular size of the service area in the widest part thereof; maintaining, during movement of the relay satellite, the direction of the axis of the central beam of the multibeam antenna towards the centre of the service area; determining active beams whose areas overlap with the service area, and passive beams whose areas do not overlap with the service area; connecting the active beams to on-board transceiving equipment; periodically checking coincidence of the areas of the beams with the service area; based on the checking results, disconnecting from the on-board equipment those active beams whose areas do not overlap with the service area, and connecting to the on-board transceiving equipment those passive beams whose areas overlap with the service area.

EFFECT: high efficiency of using on-board transceiving equipment of a relay satellite involved in forming multibeam coverage of the service area.
