精度和完备性在GALILEO局域监测网中变化规律研究

The study on the change rule of the precision and integrity in the GALILEO local monitoring network

完备性是飞机飞行安全的重要指标之一。本文在网形固定的情况下,利用GALIEO模拟数据,计算飞机的精度和垂直保护水平(VPL),并分析飞机在监测网中不同位置时,精度和垂直保护水平的的变化规律,得到影响精度和垂直保护水平的因素。

Integrity is one of the most important indexes for the plane’s safety. In this article, the author uses data of GALILEO simulation to compute the precision and vertical protect level and analyzes the changing disciplinarian when the plane is in different places in the monitoring network .At last, the author gets the factors which affect the precision and the vertical protect level. The study on the change rule of the precision and integrity in the GALILEO local area augmentation of monitoring network lays a foundation for the establishment of the local area augmentation system, which will satisfy the requirement of the civil aviation navigation system.
