Abstract

This paper presents developed method of a posteriori optimization of measurement results of active geodesic monitoring networks with taking into account the parameters of accuracy and reliability. Filtering the measurement results of active geodetic monitoring networks is in out of order exclusion vectors with maximum corrections, which is determined from successive iterations of network adjustment. After each iteration it’s determined the mean square error of unit weight and the parameter of network reliability. Sifting vectors with maximal errors leads to accuracy improving and reliability deterioration of network. Using entropy approach is defined group of vectors in which the value of accuracy and reliability is optimal. Using the developed method performed a posteriori optimization of active precision geodesic monitoring network of the Dnieper, Dniester and Kanev HPP. The represented method can also be used for the optimization of any active geodesic monitoring networks with large quantity of redundant measurements
