Patent ID: 8711033

Claim:
A method of geolocation of a device transmitting a signal containing at least one message to a plurality of N vis relay satellites visible from said device, the method comprising: determining times of reception T Ri of said message by the N vis relay satellites, determining, from said times of reception T Ri and with respect to a time T e of transmission of the message by the device, the pseudo-distances D i between said device and each of said relay satellites N vis searching for and acquiring a number N of satellite radio navigation signals, N being at least equal to 2+m−N vis where m is a number of space coordinates of the device and N vis is the number of relay satellites visible from the device, determining an information on a time lag between the time of transmission of each radio navigation signal j and the time of reception of each radio navigation signal j T Ri by the device, determining, from said information, the pseudo-distances D j (GNSS) between the device and each of the N radio navigation satellites, and determining the position of the device from the pseudo-distances D j between the device and each of the N vis relay satellites and from the pseudo-distances D j (GNSS) between the device and each of the N radio navigation satellites.
