Title GPS receiver Navigation Positioning Algorithm

Abstract With the global positioning system (GPS) continues to mature and develop, it has been applied to various fields, the GPS receiver navigation algorithm has become an important part of global positioning, positioning accuracy determines the range of application of the GPS receiver, the more high-precision positioning algorithm for GPS navigation plays an important role。 This article describes the components of the GPS signals as well as a major role in various parts of the receiver, the GPS positioning principle of a simple description, then do a summary on the positioning method, it describes the derivation of the carrier phase smoothing Pseudo - distance positioning algorithm highlights pseudo-range positioning operation step and MATLAB simulation of positioning error simulation results were analyzed, based on the results obtained localization algorithm and improved localization direction。

Keywords GPS positioning principle Pseudo-range positioning Carrier smoothed pseudo-range MATLAB Positioning error
