Abstract:
A system of positioning mobile objects, comprising a satellite receiving unit arrangeable on a mobile object; a plurality of navigation satellites rotating on earth's orbits so that their positions continuously change relative to a stationary point, and so that satellite signals are received by said satellite receiving unit for determination of their position coordinates; a stationary reference satellite receiving station arranged so that said satellite receiving unit of said mobile object receives a correction signal with correction data from said stationary reference satellite receiving station for exactly known position coordinates and for a computation of corrected position data; an electronic evaluating and processing unit through which the correction signals received from at least two reference satellite receiving stations are supplied, said evaluating and processing unit determining from said correction signals of the different stationary reference satellite receiving stations an optimal error correction signal, so as to transmit the determined error correction signal as a correction signal to said satellite receiving unit arranged on the object for a position correction.
