【摘要】 EGNOS是一个广域增强系统,向用户提供电离层改正数是其服务内容的一部分。本文分析了EGNOS电离层改正数的结构,介绍了用户的电离层改正数算法流程。结合EGNOS在中国测试的实际数据,对EGNOS电离层改正数进行了分析。通过对EGNOS的电离层改正数分析可以为我国的广域增强系统提供技术参考。更多还原

【Abstract】 EGNOS is a wide area augmentation system.One of the functions of EGNOS is to provide ionosphere delay correction to users.This paper introduces the structure of ionospheric delay correction,and gives the users process flow of the ionospheric delay.The real ionospheric correction data is analyzed from the EGNOS test in China.It may provide technical reference for WAAS of our country,by analyzing the EGNOS ionospheric correction.更多还原
