Reliable results of geodetic monitoring depends on several factors. One of the main factors is reliability of geodetic points taken as the source for the creation of geomonitoring network. According to the current normative documents for the creation of horizontal and vertical geodetic networks, the stability of the geodetic points should be determined by the results of periodic monitoring of their coordinates. As practice shows this is not enough, because geodetic reference points simultaneously offset with the monitoring object. Therefore, the assessment of source reliability and systematic control of the base points of geomonitoring network are important. Purpose. To increase the reliability of results of geodetic monitoring which based on the use of stable reference geodetic points. To develop probabilistic intervals of errors of determination of coordinates of geodetic points of various classes based on which we can judge their offsets in the selection of a stable geodetic points. Conclusion.By sampling stable reference geodetic points on the interval estimates of the errors of the coordinates with a given level of reliability and defining the mode of their control, you can create a reliable geodetic monitoring network. Using this network for geodetic monitoring of engineering facilities will allow us to obtain reliable, valid observation results.
