Zusammenfassung:A method for establishing control networks or deformation fields from sequential geodetic measurements is developed. The method is based on the use of the free network solution which is obtined from the results of adjustment by the method of condition equations. The conditions applied in this paper are as follows: (1) Repeated geodetic measurements are carried out at different epochs to determine the coordinates of the points which make up a network. (2) the network of the one epoch should be fitted in that of the other epoch. (3) the weight given at each point for fitting should be arbitrary. Applications of the method are outlined and illustrated by elementary mumerical examples.
