浅谈奥米加导航系统的位置误差

A Tentative Discussion of Positioning Error of Omega Navigation system

奥米加导航系统是一种全球性导航系统.在一般天气条件下,该系统具有良好的导航性能,但是在复杂天气条件下,也暴露出了一些缺点或不足。本文针对使用中出现的问题,根据其工作特性、信号格式、信息处理、定位计算,误差处理方式进行一些理论分析,并对改进系统操作进行一些探索。

Omega navigation system is a world-wide navigation system.Although it operates well under normal weather conditions,it has exhibited some disadvantages or short- ages undetr complicated weather conditions.This paper makes a theoretical analysis,based on practical problems,of its operating properties,signal format,informatiom disposal,posi- tion calculation and error correction mode,and explores possibilities of improving the opera- tion of the system.
