| 摘 要： | 介绍了在短基线状态下利用单频单历元双差载波相位定位时模糊度固定的基本理论.结合正则化理论和阻尼矩阵的思想,提出了一种用改进的正则化方程来改善法方程病态性的方法.算例分析表明,应用改进的正则化算法可以改善法矩阵的病态性,得到更加精确的浮动解,利用LAMBAD方法搜索可得到准确的整周模糊度解.

| Abstract: | This paper introduces the basic theory of carrier phase ambiguity solution for single frequency single epoch.Through the combination of regularization theorem and damp matrix,an improved regularization method is brought forward to ameliorate the ill condition of normal equation.The analysis of algorithm examples has proved that the application of improved regularization method can ameliorate the ill condition of normal equation,and precise float solution can be gained.Precise integer ambiguity can be search... |
