Method for locating aircraft independently from any satellite navigation system.

摘要

The method involves permanently calibrating a bias of time deviation between automatic dependent surveillance-broadcast beacons (B1i, B2i) of aircrafts (Ak) estimated on history of visibility passages of the beacons. Pseudo-distances between a visibility aircraft and one of the beacons are calculated by the bias of calibrated time. Location of the aircrafts is calculated from the pseudo-distances and a matrix of axes based on square resolution equal to instantaneous resolution of global positioning system position and a threshold of rising reference signal emitted by the beacons.
