Abstract:
This article deals with a critical issue of accuracy degradation in high-precision engineering geodetic surveys. This problem stems from the discrepancy between the centimeter-level precision of satellite GNSS measurements in the global ITRF frame and the significant coordinate errors of points in the state and local geodetic networks. A comprehensive mistake assessment method was developed, based on the analysis of normal convergence anomalies and the construction of non-linear regression models for spatial distribution of geodetic network distortions. Experimental verification conducted over a territory exceeding 1000 km in the Siberian Federal District demonstrated that the method enables identification and elimination of systematic errors, thereby doubling the accuracy of spatial data alignment in the GSK-2011 State coordinate system
