- Measurements of structures must be precise and accurate as they affect the quality of the final result of geodetic tasks. In some cases there is a risk of committing a gross error. Diagnostic analyses may allow such an observation in to the adjustment and estimation of unknown parameters. The paper presents results of network deformation and robustness analysis based on the characteristics of network accuracy and reliability. The maximum undetectable error that may occur in an individual observation constitutes the source of deformation. The method tested in the present paper is proposed in Prószyński and Parzyński (2009). The paper evaluates theoretical relationships and their utility for analyses of large geodetic networks. Additionally, the paper attempts to transfer the presented relationships to the case of free adjustment, which was not included in theoretical derivations in the paper mentioned above. The research has been conducted using a computer generated 2D linear-angular network. The analysis focuses on the results of network deformation, depending on the assumed reference system. Moreover, an attempt has been made to modify the proposed method of network reliability analysis for the case of free adjustment.
