METHOD OF REDUCING FREQUENCY INTERFERENCE AND SATELLITE COMMUNICATION SYSTEM Russian patent published in 2024 - IPC H04B7/185 H04W84/06 

FIELD: satellite communication.

SUBSTANCE: said technical result is achieved by configuring a satellite communication system, determining a first range of areas, in which the angle of spatial isolation between the LEO satellite and the GEO satellite does not satisfy the minimum angle of spatial isolation in the service areas of the movable narrow beams, allowing the movable narrow beams not to enter these areas, and when the mobile narrow beams of the transmitting and receiving user antennas of a plurality of neighboring LEO satellites provide services in the same area, calculating the spatial isolation angles between the mobile narrow beams of the transmitting and receiving user antennae of any two adjacent LEO satellites, and in response to the fact that the spatial isolation angle does not satisfy the minimum spatial isolation angle, assigning different sub-frequencies to the movable narrow beams which do not satisfy the minimum spatial isolation angle.

EFFECT: reduction of frequency interference between mobile narrow beams of the transmitting and receiving user antennae of the LEO satellite and the GEO satellite and reduction of frequency interference in the satellite communication system.
