| titleOfInvention | INSTRUMENT LANDING SYSTEM. |
| abstract | In a single-frequency precision guidance system for instrument landing, a DME interrogator (50) is used in the aircraft and a DME receiver (60) installed on the ground, each tuned to the frequency of the same DME channel, to interrogate only one selected ground station (29, 32, 21, 22, 33, 34) and identify it by the fact that its responses are synchronous in the aircraft (3, 8) with the interrogations, the responses and the interrogations being also used to get the distance to the floor installation. This technique uses DME interrogators (50) already installed on board to carry out selective interrogation of a desired landing installation (60, 29, 32), in order to eliminate any need to install equipment in the aircraft. additional special to obtain the desired uniqueness of interrogation and identification of the ground installation described by the present invention. |
