Abstract
The locations of pseudolites and the location of a stationary reference station are previously known by a user processing unit, and codes and carrier phase of signals transmitted from the pseudolites are measured by the stationary reference station, a moving reference station and a rover receiver. Data of the codes and the carrier phase measured by the stationary reference station, the moving reference station and the rover receiver are transmitted to the user processing unit using a data link. The user processing unit determines a baseline between the stationary reference station and the moving reference station, and a baseline between the moving reference station and the rover receiver. The two baselines and the previously known location of the stationary reference station are employed to determine the position of the rover receiver.
