Abstract

This scientific article considers the estimation of accuracy of mean height anomalies determined on GPS/first order levelining points based on using the equivelence equation of the GPS/leveling height anomaly and gravimetric height anomaly (determined from the EGM2008), and using the Hon Dau local Geoid with real geopotential W0 = 62636847.2911 Research results on GPS/first order leveling points shows that the accuracy of the state Quasigeoid reached at level ± 7.2 cm.
