Abstract
A method between a geolocation receiver and an identified transmitting satellite, the receiver being able to receive a composite radio signal including a plurality of navigation signals each transmitted by a transmitting satellite that is part of a satellite constellation, a method for validating the synchronization between a geolocation receiver and a transmitting satellite during a phase for acquiring an augmentation signal including geolocation correction and integrity data; the methods include, for each identified transmitting satellite, extracting received ephemeris words or received words of any type of the received signal associated with the identified satellite as it is received, and comparing at least one received word with at least one word of the same rank or stored for the identified satellite and/or for at least one other satellite; the validation or non-validation of the synchronization with the identified transmitting satellite depends on a predetermined false alarm probability and/or non-detection probability.
