| 摘 要： | 在多天线GPS姿态确定系统中,整周模糊度的确定一直是姿态解算的一个难题。针对载波相位双差模型,本文提出一种新的几何解算双差整周模糊度的方法。该方法首先利用C/A码数据完成姿态初步解算;然后根据初步解算的姿态参数、各天线间基线分量参数和卫星到接收机在当地水平坐标系中的向量,再利用本文提出解算双差整周模糊度几何算法求取整周模糊度双差值;将整周模糊度双差值代入载波相位双差模型反解精确的各天线坐标分量,由取得的各天线坐标分量解算得到精确的姿态参数。同时,应用本文所提出的方法,对采集的GPS多天线静态数据和动态数据进行了姿态测量解算,验证了所提方法的有效性。

| Abstract: | In a GPS Multi-antenna system,the integer ambiguity resolution is always a crucial problem in the attitude determination.Aiming at the model of double-difference carrier phase,a new geometric method for double-difference integer ambiguity solution is proposed in this paper.Firstly,we get the initial attitude solution from the C/A code data;then a new geometric model is established to get the carrier phase double-difference integer ambiguities according to the attitude parameters from the initial solution,co... |
