METHOD OF CONTROLLING THE TRANSMISSION POWER OF MESSAGES IMPLEMENTED BY A SYSTEM TO AVOID COLLISION IN FLIGHT OF AIRCRAFT.

摘要

A method of controlling the transmission power of messages implemented by a system to avoid the collision in flight of aircraft. The present invention is a method of controlling the transmission power of messages implemented by a system to avoid the collision in flight of aircraft, said system being of the type comprising an anti-collision device (10) and a transponder (20) equipping each plane. According to the present invention, said method comprises - a measurement step (E5) for measuring at least the value, called the quality value, of a quantity representative of the quality of reception of the radio frequency signals carrying response messages (Rep) transmitted by a transponder (20) of an intruder plane - a control step (E27) for controlling the transmission power (Pt) of the radio frequency signals carrying said response messages (Rep) according to the value or quality values and measured. The present invention also relates to a system for preventing the collision in flight of aircraft.
