Title (EN) TRANSPONDER LANDING SYSTEM AUGMENTATION OF THE GLOBAL POSITIONING SYSTEM
(FR) ACCROISSEMENT DE SYSTÈME D'ATTERRISSAGE PAR TRANSPONDEUR DU SYSTÈME MONDIAL DE LOCALISATION
Abstract:
(EN) A GPS navigation system augmentation using a transponder landing system. Initially, the position of a reference ground station is determined. When an aircraft using an on-board GPS navigation system approaches the ground station, the ground station accurately determines the position of the aircraft using the aircraft's transponder replies. In addition, the ground station receives a current position for the aircraft measured by an on-board GPS navigation system. By comparing the position of the aircraft determined from the transponder replies with the GPS- calculated position provided by the aircraft, the ground station determine error information for the on-board GPS navigation system. The ground station then transmits the error information back to the aircraft. Using this error information, the on-board GPS navigation system can improve the accuracy of future position calculations for the aircraft.
(FR) La présente invention concerne l'amélioration d'un système de navigation GPS au moyen d'un système d'atterrissage par transpondeur. Au départ, on détermine la position d'une station terrestre de référence. Lorsqu'un aéronef utilisant un système de navigation GPS embarqué s'approche de la station terrestre, la station terrestre détermine avec précision la position de l'aéronef au moyen des réponses du transpondeur de l'aéronef. En outre, la station terrestre reçoit une position actuelle pour l'aéronef mesurée par le système de navigation GPS embarqué. Grâce à la comparaison de la position de l'aéronef déterminée à partir des réponse du transpondeur avec la position calculée par GPS fournie par l'aéronef, la station terrestre détermine une information d'erreur pour le système de navigation GPS embarqué. La station terrestre retransmet ensuite l'information d'erreur à l'aéronef. Grâce à cette information d'erreur, le système de navigation GPS peut améliorer la précision des calculs ultérieurs pour l'aéronef.
