WebThe surface of the Earth is described as near as possible by a spheroid, i.e. a 3D shape. To all intents and purposes for this discussion of using RTK for tide correction we consider just the one ellipsoid (meridian) on the Earth’s surface where the User is located. The ellipsoid is a single “ring” whereas the spheroid is the 3D shape. Webbe observed if Earth were a perfect (no geologic or topographic complexities), rotating ellipsoid is referred to as the normal gravity. Gravity INCREASES with increasing latitude. Correction is ADDED as we move toward the equator. Correction is applied ONLY for relitive movement in the N-S direction. Correction for a given

Webtides and solid Earth tides. Ocean tide corrections are computed from a model that defines the tidal surface relative to a mean surface associated with the deformed solid Earth. The solid Earth tide correction reflects the vertical displacement of the crust of the Earth with respect to the ellipsoid due to the attraction of the Sun and Moon. This jim banks comments about january 6WebThe lunar tidal effect is calculated in an analogous way. Again, one has to realize that Earth is in a free fall towards the Earth-Moon center of mass.
