摘要
间接平差以误差方程规律性强、便于用计算机编程解算、精度评定方便、所选参数往往就是平差后所需要的成果等优点在测量平差中得到了广泛的应用。本文根据水准网间接平差的特点,改变常规需要构建误差方程计算其系数阵再构建法方程的方法,直接根据观测信息构建法方程实现水准网间接平差。
Parameter adjustment, which has many advantages convenient for programming and assessing precision, the choiced such as the strong rule of error equation which is very parameters are just the achievement after adjustment and so on ,is used extensively in survey adjustment. According to the feature of level network' s parameter adjustment, this paper change the conventional method which builds error equation to calculate coefficient matrix firstly and then builds normal equation, it bring about level network's parameter adjustment through observing information directly to build normal equation.
