EGNOS数据处理模型与实例

主要分析研究了EGNOS系统测试采用的误差修正模型和定位保护精度算法,并通过比较一次实测静态数据单点解算和差分解算的不同效果来说明误差模型的修正效果和保护精度算法的有效性。事实证明EGNOS系统数据处理采用的误差修正模型效果是明显的,采用的定位保护精度算法是有效的。

EGNOS data process models and one instance

This article studied the error correction models used in EGNOS test.And the function of these models are proved to be powerful by comparing the performances between the stand-alone solution and the wide area difference solution of a static data logged in one test,as well as the algorithm to solve the HPL and VPL of position is proved to be availability.The factual result show that the models can improve the performance of ESTB greatly and the algorithm of HPL and VPL is effective.
