Method and device for ensuring the accuracy and the integrity of an aircraft position on the ground

摘要

An assist device for ensuring the accuracy and integrity of position information of an aircraft on the ground includes a processing unit for determining in the airport (AE) a zone (ZP) of insensitivity to multipath GPS signals, the zone (ZP) having a rectangular shape, which is determined relative to the threshold (O) of the runway, and which has a length (L1) equal to the length of the runway and a width (L2) depending on a maximum illumination distance (D). The device further includes a unit for verifying, while the aircraft is moving in the airport (AE), whether the position relative to position information of the aircraft is inside said runway zone (ZP). A method for ensuring the accuracy and integrity of position information of an aircraft on the ground is also disclosed herein.

主权项

1. A method for ensuring the accuracy of position information of an aircraft rolling on the ground in an airport, comprising:
receiving information relative to at least one runway; determining a maximum distance (D) sensitive to multipath type electromagnetic illumination, in function at least of the height of the buildings on the airport; determining by said information and said maximum distance (D), a runway zone (ZP) with rectangular form relative to the threshold (O) of runway, and having a length (L1) equal to that of the runway and a width (L2) depending on said maximum distance (D); and during the travel of the aircraft in airport (AE), automatically and repetitively: receiving position information of the aircraft; and verifying whether the aircraft position is inside said runway zone (ZP).
