Özet:    Satellite-based measurements have been performed on EDM Calibration Base by Classic GPS, Network RTK and Static GPS methods and terrestrial measurements have been conducted with Total Stations in this study.  FKP, VRS and MAC correction methods were used in the Network RTK method. The objective of this study was to make statistical comparisons of distances obtained by using all combinations between different measurement methods.  Analysis of Variance (ANOVA) was utilized for this purpose.  It was determined that there was a statistically significant difference between the measuring methods used in the one-way ANOVA test. The differences and standard deviations obtaind by the comparison of distances based on different measurement methods between benchmarks have been varied from mm to cm. The results obtained by the static GNSS surveying method are better than the standard deviations obtained by other methods of measurement and equipments when compared. The methods according to the distance measurement precision have been listed from the highest precision to low as Static GNSS, terrestrial surveying, classical RTK, FKP, VRS and MAC respectively. The distance measurement precision of Terrestrial measurement was found to be better than the classical RTK and NRTK measurement methods. The distance measurement precision of the classic RTK method was better than NRTK methods obtained by the different correction methods. In comparison, of NRTK correction methods in itself, the best results were obtained by FKP method.
