Root mean square (rms) about mean of GNSS / levelling minus gravity field model derived geoid heights [m]

The following table shows a comparison of quasigeoid heights derived from the models with GPS / levelling derived geoid values from USA, Canada, Europe, Japan and Brazil. Note that the differences also contain the cut-off error of the models, i.e. the unmodelled short wavelength part of the gravity field. The GPS / levelling data sets are from:

• USA; Milbert, 1998
• Canada; Marc Veronneau, Canadian Geodetic Survey, Natural Resources Canada, updated in 2019
• Europe; Ihde et al., 2002
• Australia; W. E. Featherstone, N. J. Brown, J. C. McCubbine & M. S. Filmer (2018):
