摘要
首先对海上运动平台多站时差定位系统定位精度的影响因素进行了理论分析。在此基础上,针对时差误差、站址误差、基线长、基线夹角对定位精度的影响进行了仿真分析。最终结合海面上的复杂环境背景,判断定位精度是否达到指标,并根据定位精度指标反推出达到该定位精度需要的多站布站方式等。
This paper firstly analyzes the factors influencing the positioning accuracy of the multi-station time difference of arrival(TDOA)positioning system in offshore mobile platform,on this basis,simulates and analyzes the effects of time difference error,site error,baseline length and baseline angle on positioning accuracy.Finally,combined with the complex environmental background on the sea surface,this paper judges whether the positioning accuracy has reached the index,and deduces the multi-station layout mode required that can satify the positioning accuracy according to the positioning accuracy index.
