1. A method of locating an aircraft, comprising:
- a first step of locating the aircraft in terms of distance and angle by means of a radar;
a second step for refining the location by means of at least one airborne beacon aboard the aircraft and of at least one ground beacon whose position is predetermined with respect to the radar, the measurement of the position of at least one airborne beacon being performed by the radar by differential measurement between the position of at least one ground beacon and of at least one airborne beacon.

Abstract
The present invention relates to a method and a device for locating aircraft. A radar (3) performs distance and angle location of the aircraft. Location is refined by means of at least one airborne beacon (4) aboard the aircraft and of at least one beacon (5) whose position is predetermined with respect to the radar (3), the measurement of the position of the airborne beacon (4) being performed by the radar (3) by differential measurement between the position of at least one ground beacon (5) and of at least one airborne beacon (4). The invention is in particular used for the automatic guidance of drones in the approach and landing phase.
