摘　　要：推导了间接平差模型转化为条件平差模型的矩阵运算方法,采用了先间接平差、后条件平差的2套平差的数据处理方法,综合了间接平差和条件平差的优点,使得数据处理过程引入了较全面的质量检查机制,软件实现了的控制网闭合差检查功能。The general method of transforming the indirect adjustment model into the conditional adjustment model is derived.Two sets of data processing methods of adjustment are adopted,which are indirect adjustment first and conditional adjustment later.The advantages of indirect adjustment and conditional adjustment are integrated.The data processing process has a more comprehensive quality inspection mechanism.The software realizes the function of closing error testing of control network.
