Pseudorange error correction of clear/acquisition code for civil users of GPS

The present investigation is concerned with the development of a pseudorange error correction concept for a navigator who uses the Global Positioning System (GPS). Attention is given to the proposed procedure, the generation of the GPS satellites in their true orbital positions, the GPS satellite constellation generator, aspects of satellite in-view determination and selection, and a simulation of the GPS navigation model. The results of the simulation show that the accuracy of user position measurement is restored after satellite range correction is implemented.
