| Abstract: | A new algorithm for the real-time GPS orbit determination is established in this paper. In this algorithm, satellite orbit parameters are updated using normal equation addition method. Then, the predicted orbit is calculated according to the numerically differential relationship between the satellite orbit and the orbit parameters. The real-time orbit predicted by this algorithm using the observations of the chinese regional GPS tracking network are analyzed in detail. |
