| 摘 要： | 介绍了北斗系统下格网电离层延迟算法原理及建模方法。利用25个参考站的模拟数据,建立了覆盖我国地区的格网电离层延迟模型。通过仿真给出格网点(35°N,115°E)的格网电离层垂直误差及用户穿透点(36.94°N,118.44°E)的用户电离层垂直误差在一天内的变化,结果显示一天内格网电离层垂直误差及用户电离层垂直误差的平均值分别为0.871m和0.877m。

| Abstract: | The principle and modelling based on grid ionospheric delay algorithm in beidou is introduced.A grid ionospheric delay model covering China is established by using the simulation data of 25 reference stations.Regarding a typical ionospheric grid point(IGP)(35°N,115°E) and a typical ionospheric pierce point(IPP)(36.94°N,118.44°E),the variations of the grid ionospheric vertical error(GIVE) and the user ionospheric vertical error(UIVE) in a whole day under quiet ionosphere are presented.The results show that the mean of UIVE and the mean of GIVE are 0.871m and 0.877m respectively. |
