基于Gauss坐标系的测向误差统计模型分析

Models Analysis of Finding Error Based on Gauss Coordinate

由GPS测量的经纬度计算目标方位,是统计测向误差的重要内容,采用的坐标系不同,带来的统计误差不同。介绍了基于Gauss平面投影坐标系的计算方法,模型清晰,方位角度计算方便,适用于测向误差的统计。给出了计算模型,对由中央经线取值产生的误差进行了仿真分析,并介绍了消除统计误差的简单方法.

Calculating target bearing by longitude and latitude azimuth is the key process to statistrics derection finding error,different models,different errors.In the way to transform Gauss coordinate from earth coordinate based on Gauss planar projection coordinate,which is the same with statistricsing derection finding error, not only models are clarity but also it is convenience to calculate angle. In this article,we supply calculation model , simulation analysis to error caused by the center longitude and theoretic gist which could advance statistrical precision of detection finding results abstractly.
