PDOP因子在相对导航航路分析中的应用研究

Research on application of PDOP factor in the analysis of the relative navigation route

基于分析相对导航定位精度受到PDOP因子影响的目的,采用Map X电子地图软件设计测试程序,计算出地图中各个位置的PDOP值,以此为依据设计外场试验航路,通过对试验航路进行仿真测试,分析了不同航路的PDOP因子和相对导航结果,结果证明PDOP因子更有利的航路能够获得明显更高的相对导航定位精度。

Based on the purpose of analysis of relative navigation positioning accuracy impacted by PDOP factors using MapX electronic map software design test procedures, calculate the PDOP value of each location in map. To design the outfield test route on the basis of this. By the simulation test of the test route, analyzes the PDOP factor of different mutes and relative navigation results, results show that route PDOP factor more favorable to obtain the relative navigation and positioning accuracy significantly higher.
