| Abstract: | Based on the dynamic simulation function of MATLAB, the real-time calculating and analysis of the GPS satellite constellation play a crucial role in reducing the space where the best satellite constellation is selected and in decreasing the time of constellation-selecting, which makes the quality of real-time selecting satellites better. Combined with the method of pseudo-range positioning,the experiments of the vehicle navigation prove its availability and precision can meet the requirements of the projects. This method of simulation also contributes to the prediction of the GPS constellation. |
