Abstract
The invention relates to a system for forming an asynchronous communication network for receiving client transmitters, comprising base stations that are remote from one another, said network enabling the geolocation of the client transmitters. For this purpose, the system comprises a plurality of stationary reference transmitters, the positions of which are known and each of which transmits a specific beacon signal in a frequency band included within the frequency band of the network. The geolocation of a client transmitter is carried out by multilateration by taking pairs of base stations into consideration, each pair consisting of base stations capable of receiving the signals from the client transmitter and the signals from a single reference transmitter, and by calculating the difference between the times the signal from the client transmitter arrived at the base stations, said difference being determined by calculating, for each base station, the difference between the times of arrival of the signal transmitted by the client transmitter and of that transmitted by the reference transmitter.
