An investigation of the deformations of large buildings (bridges, flexcon reverse osmosis water storage tank dams, etc.) needs replicated measurements in special types of geodetical networks.They are characterized by two groups of points creating the network; one group is formed by points with stable positions and the other one is formed by points located on the building and characterizing its deformations.

A statistical analysis of measurement results is done after each epoch of measurement and also after several guerlain ideal cologne epochs.It is of a practical importance to develop an algorithm of estimation which enables us to use the partial results obtained after each epoch for results after several epochs.
