摘要
本文的目的是研究影响天文导航系统定位精度的两个因素–时间和重力矢量方向。首先对影响天文导航系统定位精度的两个因素进行了理论分析并首次给出了理论公式,然后通过计算机仿真试验分析了两个因素对天文导航系统定位精度的影响程度。最后给出了对工程实践具有指导意义的结论。
The article’s aims to research two elements affecting positioning accuracy of celestial navigation system, time and the direction of the gravity vector. At first,these two elements affecting position accuracy of aeronautic celestial navigation system are analyzed in theory,and their academic formulas are presented for the first time. Then computer simulation is used to study how the two elements affect the positioning accuracy of aeronautic celestial navigation system. At last some directional conclusions to engineering are given.
