摘　　要：阐述GPS测姿基本原理和采用多天线测姿方法,针对影响GPS测姿精度因素进行分析,提出应用最小二乘法进行载体姿态参数计算和动态模糊度解算的方法.比对试验和精度分析表明,使用最小二乘法进行载体姿态确定是最优的,使用最小二乘搜索法进行动态模糊度解算是非常有效的.The basic principle of attitude determination by multi-antenna GPS technology is described. The least square algorithm for calculating the attitude parameters and the dynamic ambiguity is presented. The test results and the accuracy analysis have demonstrated that the least square estimation procedure is optimal for the attitude determination and the analysis algorithm of dynamic ambiguity is effective.
