REPEATER OF RANGE FINDER OF LANDING RADIO BEACON GROUP Russian patent published in 2022 - IPC G01S13/76 G01S1/16 G01S13/91 

FIELD: aviation.

SUBSTANCE: invention relates to aviation radio navigation; it can be used in rangefinder channels of landing radio beacon groups (hereinafter – LRBG), used on airfields for landing of aircrafts of civil, experimental and state aviation. The claimed range finder repeater of a landing radio beacon group is a composite part of LRBG system and provides, by a request radio signal of onboard aircraft equipment, the measurement of inclined range onboard the aircraft by a response radio signal of the range finder repeater (hereinafter – RFR). The repeater contains sequentially connected receiving and transmitting antenna 1, receiver 2, threshold unit 3, first decoder 4, delay element 5, first encoder 6, and transmitter 7, an output of which is connected to receiving and transmitting antenna 1. Second decoder 8, storage device 9, synchronization device 10, second encoder 11, and element OR 12 between an output of the first encoder and an input of the transmitter are additionally introduced to the claimed device.

EFFECT: increase in information content of a rangefinder channel of RFR.
