摘要
本文主要对现有的总体最小二乘平差理论进行了相关分析,结合其两种解算方式包括奇异值分解法和迭代解法,进行了相关的理论阐述,最终得到了总体最小二乘平差迭代解法更适合应用与测量平差分析。
In this paper,we mainly analyze the existing theory of least-squares adjustment,and combine the two methods of calculation including singular value decomposition and iterative method to explain the relevant theory.Finally,Multiply adjustment iterative method is more suitable for application and measurement adjustment analysis.
