ON-BOARD INFORMATION-NAVIGATION COMPLEX Russian patent published in 2018 - IPC G01C21/24 H04B7/185 

FIELD: navigation.

SUBSTANCE: invention relates to the field of onboard information and navigation equipment for space vehicles and is intended for the formation and emission of navigation radio signals of the GLONASS system, generation, emission, data reception and measurements on an inter-satellite radio link, as well as to provide autonomous operation of the GLONASS space satellite navigation group. On-board information and navigation complex includes a digital control unit, a synchronization signal generation unit, a navigation subcomplex, a sub-complex of inter-satellite radio links, a low-power onboard network switch and an onboard power switchboard. At the same time, the navigation subcomplex includes the drivers of the navigation radio signal of the L1, L2 and L3 bands, radio transmitting devices of the range L1, L2 and L3, the antenna-feeder device of navigation signals and the block of logic and switching of the navigation subcomplex. Sub-complex of inter-satellite links comprises an inter-satellite radio transceiver module, a radio transmitter of the S-band transmitting an antenna-feeder device, receiving antenna-feeder device, low-noise amplifier and a block of logic and commutation of the inter-satellite radio link, low-power and power switches of the on-board network.

EFFECT: technical result is the synchronous formation and emission of navigation and inter-satellite signals.
