导线网坐标差观测值相关平差方法研究

Study on the Correlated Adjustment Method of Traverse Network Coordinates Difference Observation

提出了利用普通间接平差和相关间接平差两种平差方法相结合,进行以坐标差作为观测值进行导线网相关平差的方法。在该平差方法中,利用普通的简介平差原理推求出坐标差观测值的相关协因数阵,并以此作为已知数据进行以坐标差观测值作为观测值的导线网的相关平差。

With the integration of general indirect adjustment and correlated indirect adjustment methods, this paper put forward the correlated adjustment method of traverse network by using coordinate difference as observation. In the adjustment method, it induced the correlated covariance matrix of coordinates difference observation based on the principle of general indirect adjustment. Then it implemented the correlated adjustment for traverse network taking coordinates difference observation as observation.
