Abstract
A system of positioning mobile objects has 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 the satellite receiving unit for determination of their position coordinates, a stationary reference satellite receiving station arranged so that the satellite receiving unit of the mobile object receives a correction signal with correction data from the stationary reference satellite receiving unit 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, the evaluating and processing unit determining from the 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 the satellite receiving unit arranged on the object for a position correction.
