AIRCRAFT LANDING MULTISTAGE SYSTEM Russian patent published in 2013 - IPC B64D45/04 G01S1/16 

FIELD: transport.

SUBSTANCE: invention relates to aircraft landing systems. Proposed system comprises ground requester 1 connected via radio line with aircraft control onboard hardware 4 and, at least, three ground receivers 6 of reply signals connected with ground control computer 8. Said aircraft control onboard hardware 4 is connected via landing control radio line 10 with computer 8 and comprises onboard teller 11 connected with aircraft onboard altitude metre 12 and with "request" and "reply" radio lines 2, 3. Said aircraft onboard altitude metre 12 comprises barometric, radio and/or laser altimetre. Pilot workstation 9 comprises indicator, manual and computerised control hardware and radio communication means connected with landing control radio line 10. Radio line 10 is composed of two-way "aircraft-ground" data exchange line. Control computer 8 is equipped with aircraft coordinates and aircraft departure from landing path computation module exploiting measured aircraft coordinates and difference in distances to aircraft relative to requester position and reply signal receivers 6.

EFFECT: higher accuracy of landing approach.
