重(磁)法基点网的平差至今仍采用较古老的波波夫平差法.这种方法从大闭合差的环开始,辗转平差,往往需经过几次循环才能完毕.为克服这种缺点,有很多人都在研究新的平差方法,例如,朱松涛的方法,他是用迭代法解广义逆矩阵来进行平差,不过在计算时需用内存较大的计算机,这在野外条件下使应用受到限制.还有王保仁的方法,他是利用近似计算的最小二乘法原理. 本文所介绍的是用增广矩阵的线性变换解线性方程组的方法,所求平差系数是一个精确的解,其计算效率要比波波夫法高几倍,而且条理清楚,不易出错. 平差过程仍是从求各闭合环的闭合差开始.如图1有四个相邻的闭合环,各边都标有增量值,增量方向
Heavy (magnetic) method base point network adjustment still use the older Popov adjustment method .This method from the large closed poor ring, rolling adjustment, often after several cycles to be completed.To overcome this There are many shortcomings, many people are studying new adjustment methods, for example, Zhu Songtao method, he is iterative method to solve generalized inverse matrix to adjust, but in the calculation of the need to use larger memory computer, which is Field conditions make the application is limited.Also, Wang Bao-ren method, he is the use of approximate calculation of the principle of least squares.In this paper, is to use the linear transformation of augmented matrix method to solve linear equations, the adjustment coefficient is A precise solution, its computational efficiency several times higher than the Popovich method, and clear, not easy to error. Adjustment process is still from the closure of the closed loop to find the difference between the poor as shown in Figure 1 has four adjacent closed Ring, all sides are marked with incremental value, incremental direction
