| Abstract: | An improved model was introduced based on the effect of periodic perturbation of the earth gravitation on the navigation satellite in the paper. The method of solving broadcast ephemeris parameters and the position algorithm of the model were given out. The simulation computation results showed that the model had strong ability to predict the orbit parameters of the satellite very accurately. |
