| 摘 要： | 根据相关平差理论，指导出两组相关观测值的逐次间接平差数学模型，提出改化第二组误差方程来消除两组间的相关性。文章给出了多组相关观测值误差方程的改化算法，并根据ＧＰＳ载波相位观测值协方差阵的特殊性，给出了改化三差误差方程的算法。

| Abstract: | Based on the theory of adjustment of correlates, the mathematical model of the adjustment in successive steps of two groups of indirect correlative observations has been deduced, and the method used to eliminate the correlation between the two groups by reforming the second group of error equations has been put forward. In the paper,the reformed algorithm of the error equations of multigroup correlation observations has been presented. Based on the specialities of covariance matrix of triple-differential observations of GPS carrier phase, the algorithm of reforming the triple-differential error equations has been given. |
