Method and geolocation validation system satellite

The invention relates to a method and a satellite global validation system. The system includes a radio navigation device (10) installed on board a movable carrier (2) having a location-based device (12) satellite capable of receiving a composite radio signal having a plurality of radio navigation signals each emitted by a satellite transmitter and comprising time synchronization information and position reference, the radio navigation device being adapted to implement a processing of radio navigation signals received to calculate the first navigation information comprising geo-position information, speed and time of the wearer. The radio-navigation device (10) is adapted to transmit the digitized baseband signals (IF1, ..., IFN) from the radio navigation signals received at the reference processing station (16), the reference processing station (16) is adapted to perform a processing (29) analogous to the treatment (20) carried by said radio-navigation device (10) of digitized signals (IF1, ..., IFN) for calculating second navigation information, and the system comprises means (22, 42) of validation of the first navigation information based on the second navigation information calculated by the reference processing station (16).
