摘要
在考虑电离层倾斜的基础上给出了一套改进的广域增强系统电离层时延网格算法,并通过模拟数据和GPS实测数据与原方法进行了分析比较,结果表明,同样条件下不考虑倾斜时产生的方差为考虑倾斜度时的2倍.
Considering the Ionospheric TEC incline, We have given an improved Grid-based Correction Algorithm for ionospheric delay in Wide Area Augmentation System (WAAS). After computing with GPS data, we have got that the variance is 1/2 reduced compared with original Grid-based Correction Algorithm.
