<p>A system for positioning an object provided with a receiver, which includes a set of pseudolites transmitting positioning signals and distributed in a constrained area, assistance means capable of communicating with said receiver and calculating a position of the object, and a server capable of dynamically configuring the set of pseudolites, the pseudolites each further having a spreading code corresponding to that of a satellite belonging to a satellite constellation in a satellite navigation system, the dynamic configuration of the pseudolites by the server is such that the spreading codes of said pseudolites correspond to spreading codes of satellites of the satellite constellation not visible to the receiver of the object, wherein the assistance means is configured to communicate to said receiver a list of spreading codes meant to be those of the satellites visible to said receiver but actually corresponds to the spreading codes of the set of pseudolites so as to deceive the receiver that can acquire the positioning signals transmitted by the pseudolites and communicate with the assistance means so that the assistance means calculates the position of the object.</p> |
