| 摘 要： | 目前世界上4大主力卫星导航定位系统的兼容技术日益提高和完善,在这种客观需求下使多系统联合定位成为可能。为达到两种系统组合定位的目的,将中国北斗二号(BD-2)与GPS技术相融合,在BD-2单系统定位原理的基础上提出了BD-2/GPS构成的组合接收系统的设计思路和BD-2/GPS组合导航定位系统的数学解算方法。在定位算法上采用了加权最小二乘法对组合导航定位系统进行解算,并通过MATLAB软件对数据结果进行计算和分析,证明了此种算法的可行性和可靠性。

| Abstract: | The world＇s four main satellite navigation and positioning system of compatible technology is improving and completing. In this case,multi-system compatible positioning will became possible. For achieving the goal of dual-system combined positioning,let the BD-2 and GPSS technique mutually fusion, this research proposed a design idea and matical algorithm of BD-2/GPS based on BD-2 single positioning system of positioning principle. A algorithm was should that using WLS method as the combined positioning system of position solution, the results of data was calculated and analyzed by the MATLAB software, the algorithm was availably and reliably validated. |
