  • In the least squases adjustment, in order to get the solutions satisfying " V T PV =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 , V = L + V and X = X O+ 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 construct and solve the normal equation system.
