GPS整周模糊度单历元DUFCOM方法扩展及定位解精度研究

Extended DUFCOM of Ambiguity Resolution for Single Epoch GPS Positioning Solution Analysis

    摘要
  • 摘要: 分析了双频相关法(DUFCOM)单历元解算GPS L1相位观测值整周模糊度理论,并对其进行了方法扩展,提出了单历元直接确定GPS L2、Ln和Lw相位观测值整周模糊度新方法。给出了扩展方法的特征值条件,从理论和实践角度对4种相位观测值在整周模糊度解算效率和定位解精度两方面作了对比分析。

     

    Abstract: The ambiguity resolution theory of GPS L 1 phase observation using single epoch data based on DUFCOM was analyzed, the extended DUFCOM was developed. A new single epoch ambiguity fixing method was proposed for GPS L 2, L n and L w. The property of the extended method was given, f urthermore, and the efficiency of ambiguity resolution and the accuracy of positioning solution for the above four phase observations were compared in theo-ry and result.
