SATELLITE COMMUNICATION METHOD, SATELLITE COMMUNICATION SYSTEM AND ON-BOARD RADIO SYSTEM FOR LOW-ORBITING SPACECRAFT Russian patent published in 2013 - IPC H04B7/185 

FIELD: radio engineering, communication.

SUBSTANCE: method involves determining the spatial position of a low-orbiting spacecraft based on data of at least one satellite positioning system; response transmission of a registration signal for communication to a relay satellite in a wide band, said signal containing information on the position of said spacecraft; and determining the narrow controlled beam of the relay satellite, in whose coverage area the spacecraft is located, for transmitting information in a narrow controlled beam. The satellite communication system includes at least one low-orbiting spacecraft, at least one satellite positioning system and a group of geostationary communication system relay satellites. The on-board radio system of a low-orbiting spacecraft includes an active phased antenna array, an on-board communication device and a control device.

EFFECT: improved quality and reliability of communication, avoiding the need to allocate additional memory devices for the on-board radio system.
