Testing geopotential models

The actual accuracy of the geopotential value on the geoid computed from satellite altimetry recently asW ₀ = (62 636 857.5 ± 1.0) m² s^–2 makes it possible to adopt this quantity as geopotential models testing (GMT) value. However, GMT network should be established consisting of points situated near the gauge stations and of other points at small sea level heights, globally distributed. As numerical example illustrating the GMT method suggested, the recent Satellite Laser Ranging network points have been used.
