USING FREQUENCY BAND OF NON-GEOSTATIONARY SATELLITES FOR GEOSTATIONARY SATELLITE COMMUNICATION WITHOUT MUTUAL NOISE Russian patent published in 2012 - IPC H04B15/00 

FIELD: radio engineering.

SUBSTANCE: geostationary satellite communication system comprises a ground station to send signals to a GSO satellite using a GSO frequency spectrum, besides, the ground station is additionally capable of functioning in such a manner so that it sends signals to the GSO satellite using an expanded frequency spectrum, besides, the expanded frequency band comprises a geostationary (GSO) frequency spectrum and a non-geostationary (NGSO) frequency spectrum; a control centre, which may instruct the ground station, so that it sends signals to the geostationary satellite using the geostationary frequency spectrum, when it is expected that the non-geostationary satellite is located at one line relative to the ground station and the geostationary satellite; and the control centre may additionally instruct the ground station so that it sends signals to the geostationary satellite using an expanded frequency spectrum, when it is expected that neither non-geostationary satellite is available on one line relative to the ground station and the geostationary satellite.

EFFECT: improved noise immunity of communication.
