| Abstract: | In the least squases adjustment. in order to get the solutions satisfying "VTPV=min". It must first construct and solve the normal equation system no matter what adjustment method is used.and then calculate the vectors V, x. L = L V and X = XO x, using the direct algorithm proposed in this paper. we can find the same adjusted results L and X,in which it does not need to construet and solve the normal cquation system. |
