Abstract
A radio navigation system including: PA0 a means to determine, at a point (M.sub.1) of the trajectory of a moving body to be localized, the speed vector of said moving body and, possible, the "n" order derivatives of said speed vector (with n>1), PA0 a means to perform at least three successive measurements of distance, respective between a geodesic point at the ground and three successive positions (M.sub.1, M.sub.2, M.sub.3) of said moving body, PA0 a means to computer the position (M.sub.3) of said moving body by resolving a system of equations from the results thus obtained, expressed in one and the same reference system.
