摘要
简述了EGNOS系统以及EGNOS在我国测试的基本情况,详细介绍了静态测试的数据处理过程,并将EGNOS差分结果与GPS未差分结果进行比较,显示差分结果优于未差分结果。同时在EGNOS数据处理中也发现许多问题,如差分结果南北方向比东西方向精度差、接收的数据中不能用于EGNOS差分定位的较多、差分定位结果超过用户定位保护限值的较多等,对此文中也进行了分析。
In this paper, the EGNOS and its testing in China is introduced. The static data processing course is given. The result shows that EGNOS is excelled in position accuracy than GPS. Some case is analysis that is found in data processing, such as, the position accuracy in northsouth directory is lower than eastwest directory, some data is not be used in data process, user protection level is excessive.
