本文利用奇异值分解法求重力网平差的条件方程以及计算各基点平差值的均方误差。并给出了与计算基点平差值权倒数有关的递推公式。最后给出了本方法的程序框图和算例。
In this paper, we use the singular value decomposition method to find the conditional equations for the adjustment of the gravity net and calculate the mean square error of the adjustment values of the base points. The recursion formulas related to calculating the reciprocal weight of the base point adjustment are also given. Finally, the method of the program block diagram and examples.
