The preliminary analysis of network accuracy is the basis for assessing the correctness of network design. The next step should be to modify the structure of the network or adjust the a priori presupposed measurement accuracy. Such an analysis facilitates determining the target network accuracy model for results of adjustment of the observational set. A control network established to determine the displacement of civil engineering objects should be structurally sufficiently accurate, reliable, and flexible. These ...

This paper proposes an adjustment algorithm of GPS vector as correlated observations. The theoretical and practical analysis has been performed for the case of a small GPS vector network (of a few hundred meters) to monitor displacements of land area or deformations of engineering structures. The detailed record of correlated observations adjustment algorithm is presented. In this case, the adjustment procedure using the least squares principle can be proven to be unchanged. The key task in this approach (adjustme...
