AIRCRAFT LANDING MULTISTAGE SYSTEM Russian patent published in 2017 - IPC G01S13/76 G08G5/02 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly to aircraft (AC) landing multi-position systems under complex terrain relief. Achievement of said technical result is enabled in system, containing ground transmitting requester and, at least, three ground response signals receivers, wherein ground response signals receivers are connected to aircraft (AC) coordinates calculating ground module output through signal connection lines and its deviations from landing path, included into ground-based control computer, which control output is connected with aircraft control on-board equipment through AC landing control radio line, wherein on-board transmitter-responder, included into AC control on-board equipment, is connected to ground transmitter-requester via radio line "request-response", on-board AC altitude meter output is connected to onboard transponder (OT) of on-board transmitter-responder input, wherein two ground response signals receivers are arranged by sides of runway axial line in its center area with displacement from axial line of not less than five hundred meters, and at least one receiver is on side opposite to aircraft landing approach, and at distance of not less than four hundred meters from runway end, besides, system contains at least two ground transmitters, connected with high-frequency outputs to corresponding said ground receivers input, made as multi-channel, connected with low-frequency outputs to corresponding input of aircraft coordinates and its deviation from landing path calculating ground module, wherein each of said transmitters and corresponding multi-channel receiver are connected to each other and structurally combined into receiving-transmitting module, wherein ground transmitter-requester is connected to aircraft coordinates calculating ground module by bidirectional bus, wherein onboard AC control equipment comprises onboard aircraft coordinates calculating module, wherein on-board transmitter and receiver are made multichannel, interconnected and connected with onboard AC altitude meter.

EFFECT: higher reliability of safe AC output for landing.
