FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a satellite communication system. A fixed transceiver system includes a first antenna designed to be positioned outside the area of non-visibility of the satellite and a second antenna connected to the first antenna and designed to be positioned in the area of non-visibility of the satellite. The fixed system is configured to receive through the first antenna downlink signals transmitted by the satellite on one downlink carrier frequency and to transmit the received downlink signals on one downlink carrier frequency in the area of non-visibility of the satellite through the second antenna. The mobile system is designed to be installed on a vehicle, includes a third antenna and a fourth antenna, and is configured to receive through the third antenna the downlink signals transmitted by the fixed transceiver system on one downlink carrier frequency, to receive through the fourth antenna the downlink signals transmitted by the satellite on one downlink carrier frequency, to determine whether the vehicle is in the area of non-visibility of the satellite or in an area of visibility of the satellite, and to transmit uplink signals on one uplink carrier frequency through the third antenna if the vehicle is in the area of non-visibility of the satellite or through the fourth antenna if the vehicle is in the area of visibility of the satellite. The fixed system is further configured to receive through the second antenna the uplink signals transmitted by the mobile transceiver system on one uplink carrier frequency and to transmit the received uplink signals to the satellite on one uplink carrier frequency through the first antenna.
EFFECT: extending communication between a vehicle and a satellite in the area of non-visibility of the satellite.
