The problem of fixed user’s state vector estimation with usage of signals of navigational space vehicles of a global navigational satellite system GPS is reviewed. With usage of a simulation model the potential accuracy of estimations of fixed user’s state vector is studied at processing of measurements by a method of a Kalman filter. With usage of known models of code pseudo-ranges and phase pseudo-ranges rates measurement fixed errors the analysis of a level of these inaccuracies have made. The input dates and outcomes of simulation are adduced with reference to conditions of Vietnam.
