Method for determining a confidence indicator relating to the path taken by a mobile

摘要

The method involves estimating successive positions of a global navigation satellite system receiver (4) e.g. global positioning system receiver, and identifying a trajectory segment. A successive auto-correlation function between navigation signals and a local replica of a code is determined. A result of summation of corrected auto-correlation functions is compared with a theoretical auto correlation function. A confidence indicator that identifies the segment corresponding to a real trajectory followed by a moving object equipped with the receiver is deduced.
