A system with fixed antennas for the guidance and control of aircraft in airport upper surfaces and in the control zone on the basis of mode s.

摘要

System for locating and unique identification of aircraft in the airport surface and in the region of the control zone and for bidirectional communication in accordance with the mode s - standard of the icao - 1 (annex 10), with at least three receiving stations, with antennas with a round the reception of the of the mode s - transponders of the aircraft outgoing squitter or answers, a the aircraft transponder interrogating transmitting station, with antennas with a round and with a device which is the principle of the hyperbola - or pseudorange - localization with the principle of two-way - distance measurement, connects to one another in such a way that points of intersection of the distance rings of the two-way - distance measurement and hyperbolas of the hyperbola - or - pseudorange to locate both on the roll - and the run-up to the airport as well as in the immediate surroundings (for example, control zone) supply the ranging results.
