Claim 12:
13. A location system comprising at least a computer, a memory and a remote communication interface suitable for communicating with a plurality of vehicles equipped with GNSS receivers via a telecommunications network, characterized in that the location system is configured to implement a method for locating a vehicle to be located (VP) comprising at least a GNSS receiver, said method comprising:
receiving a message that is transmitted by a vehicle to be located (VP) and comprises at least a GNSS signal generated by the GNSS receiver of the vehicle,
receiving messages transmitted by a plurality of located vehicles (VL) comprising a GNSS receiver, the message comprising a location of the vehicle, said location being associated with a high confidence level, and a GNSS signal generated by the GNSS receiver of the vehicle, wherein the high confidence level is based on at least one of: a model of the vehicle, a type of sensor integrated within the vehicle, sensors, which are capable of supplementing the GNSS signals, integrated within the vehicle, an image, which provides information about an environment of the vehicle and which has been acquired by a camera integrated within the vehicle, odometric data of the vehicle, accelerometric data of the vehicle, a location history of the vehicle, a strength of the signals received from GNSS satellites, and a number of GNSS satellites from which signals have been received,
selecting, from the GNSS signals received from located vehicles, the GNSS signals of which a degree of similarity with the GNSS signal received from the vehicle to be located exceeds a particular threshold, wherein the degree of similarity is based on a number of satellites visible to both the GNSS receiver of the vehicle to be located (VP) and the GNSS receivers of the located vehicles (VL) as indicated by azimuth and elevation positions of the satellites,
determining a location of the vehicle to be located, on the basis of the location of at least one located vehicle (VL) for which the GNSS signal is selected, the GNSS signal from said located vehicle, and the GNSS signal from the vehicle to be located, and
transmitting the determined location to the vehicle to be located (VP).
