| 摘 要： | 鉴于整周模糊度的快速解算是GPS载波相位测姿的一个主要技术难题,从系统实时性、动态性要求出发,给出了一个整周模糊度的快速解算的新方法。其主要特点为:利用三角函数约束条件减少模糊度搜索范围,优选指标不受基线运动状态影响,可利用多历元动态基线数据进行平差。实验结果验证了该算法的有效性。

| Abstract: | One of the main problems of GPS carrier phase attitude determination is the fast resolution of ambiguity. Based on the requirements of Real-time, a new method of fast ambiguity resolution are given in this paper, the main idea of the method is: using trigonometric function to reduce the ambiguity candidates and using dynamic baseline data to reduce the measurement error. Experimental results also proved the validity of the method. |
