Abstract: A new algorithm for regional ionosphere model based on the satellite trajectory is proposed in this paper. The algorithm principle is presented in details. In experiment, the IGS SHAO data are used to analyze the accuracy. The satellite-station model could present the abrupt variation of electron density. The model accuracy is within 1~3 TECU.

Key words: satellite trajectory, ionosphere model, model accuracy
