EGNOS系统增强服务的原理与实现

Augmentation Service Principles and Realization of EGNOS System

欧洲地球同步导航重叠服务(EGNOS)系统提供的增强服务有三类,即测距功能、广域差分校正和GNSS完好性通道。系统深刻阐明了这三类增强服务的原理与实现过程,给出了相关的算法,并推导了相应的计算公式和计算过程。

The european geostationary navigation overlay service（EGNOS） provides three augmentation services,which are the ranging function,wide area differential corrections,and GNSS integrity channel. The paper makes a systematic and deep study in the principles and realization of these three augmentation services,and presents relevant algorithms. The relevant formulas and calculation process are also derived.
