Autonomous and automatic landing system for drones
First Claim
1. An automatic aircraft landing guidance system, comprising:
- an electromagnetic detecting and locating device, positioned on the ground to measure, for at least one aircraft, the distance separating it from the aircraft and the angular position of said aircraft relative to a reference direction, based on the echo reflected by said aircraft,a first multifunction radiofrequency beacon on board each guided aircraft, the beacon comprising means for exchanging information with the detecting device and forming a point source transmitting a continuous sinusoidal wave to the detecting device,the detecting and locating device using the continuous wave transmitted by the beacon to perform a passive locating intended to improve the accuracy of the measurement of the angular position of the aircraft and comprising means for generating and periodically transmitting to the aircraft, via the beacon, information enabling said aircraft to rejoin an optimum landing path from its position.

Abstract
The invention relates to an automatic aircraft landing guidance system having an electromagnetic detecting and locating device, positioned on the ground and a first multifunction transmitting/receiving radiofrequency beacon, on board each guided aircraft and transmitting in particular a continuous wave. The detecting and locating device uses the continuous wave transmitted by the beacon to perform a passive locating intended to improve the accuracy of the measurement of the angular position of the aircraft. It also comprises means for generating and periodically transmitting to the aircraft, via the beacon, information enabling said aircraft to rejoin an optimum landing path from its position. The invention applies more particularly to the guidance of autonomous and automatic aircraft such as drones in the approach and landing phase.
