1. A radio navigation system comprising:

  • means to determine, at a point (M1) of the trajectory of a moving body to be localized the speed vector of said moving body and the "n" order derivatives of said speed vector (with n>

    1);

    means including an interrogator-responder set to perform at least three successive measurements of distance in real time with respect to a single reference, respectively between a geodesic point at the ground where said responder is located and three successive positions (M1, M2, M3) of said moving body, by measuring the time between interrogations made by said moving body and the responses of said responder;

    means to compute the position (M3) of said moving body by resolving a system of equations from the results thus obtained, expressed in said single reference system.
