摘要
考虑导航卫星受地球周期性的摄动力影响,提出了一种改进的导航卫星星历参数模型,给出了模型参数的计算方法和用该模型外推卫星轨道的计算步骤。仿真计算结果表明:该广播星历参数模型外推能力强,可较好地拟合卫星运动轨道。
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.
