Patent

CA 2345984

Aircraft position determination system includes a transmitter to transmit a signal (10), and two receivers (22, 24) to receive the transmitted signal reflected from the terrain below the aircraft, and a phase comparison apparatus (96) operating from the two receiver's inputs. A processor determines position based on the output from the phase comparison apparatus.

Cette invention se rapporte à un système de détermination de la position d'un avion, qui comprend un émetteur destiné à transmettre un signal (10), et deux récepteurs (22, 24) destinés à recevoir le signal transmis, réfléchi par le sol sous l'avion, ainsi qu'un appareil de comparaison de phase (96) utilisant les signaux d'entrée des deux récepteurs. Un processeur détermine la position de l'avion sur la base du signal de sortie fourni par l'appareil de comparaison de phase.
