Impacts of measuring and numerical errors in LSM adjustment of Local Geodetic Network

Abstract

The Local Geodetic Network (LGN) adjustment is affected by various errors, whether arisen from measuring or calculating works. The measuring errors occurred in the consistent LGS measuring can be detected by control calculations in dL using redundant measurements. The numerical errors may be detected, or the accuracy of the formulas used can be verified by control calculations in a configuration matrix A and control relations, which should show zero values.
