A method for determining the position of a decoy using at least one receiver, the method includes a step for detecting a decoy attack, a step for correcting the clock bias delivered by the receiver based on an estimated drift (D) of the clock of the receiver. The method comprises a step for differential measurements using at least three corrected clock biases (CB(t″), CB(t″), CB(t″)) and a localization step for determining the position of the decoy.

Method for determining the position of a decoy using at least one receiver

A method for locating at least one receiver in a positioning system. The system includes: at least two generators, each generator emitting, on a single carrier, at least two signals that each have a different code, and a receiver configured to detect the signals emitted by the generators. In the method: the receiver measures, for each generator, the phase difference between both signals emitted by the generator, and at least one geometric size, representing the position of the receiver in relation to the generators, is calculated on the basis of the measurements of the phase difference in order to locate the receiver in the positioning system.
