摘要
提出了一种改进的基于卫星轨迹的电离层区域建模方法,详细讨论了基于卫星轨迹电离层区域建模的基本原理,并利用IGS SHAO单基准站数据建模试验,分析验证了基于卫星轨迹的电离层建模方法的可靠性。该模型可以有效表达电子密度小区域陡变,模型区域拟合精度在1~3 TECU。
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 1GS 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.
