摘要
在附有限制条件的间接平差的应用中,若所列观测方程中实际用到的未知参数的个数少于所选参数的总数u时,就会出现法方程系数阵秩亏的问题。为了解决此问题,在理论公式推导的基础上,给出了一种新的解决方法,并结合算例进行了验证。
In the application of indirect adjustment of observations with condition equations , while the number of parameters used in the observation equations is less than the total number of choiced parameters , the coefficient matrix of normal equation will be rank defect. Therefore, we give a new method to resolve this problem in the basic of theoretical approach with formula, and validated with an example.
