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。
An improved ionospheric modeling method based on satellite orbit is presented. The basic principle of ionospheric modeling based on satellite orbit is discussed in detail. By using IGS SHAO single reference station data modeling experiment, The reliability of the ionospheric modeling method. The model can effectively express the sharp change of electron density and the fitting accuracy of the model region is 1 ~ 3 TECU.
