Rigorous geoid-from-quasigeoid correction using gravity disturbances
We present rigorous solutions for the geoid-fromquasigeoid correction (GQC) using Taylor expansions of surface gravity disturbances along the vertical from the Earth’s surface to the geoid. One solution takes advantage of the topographic potential bias at the geoid, which can be expressed by a simpl...

| Summary: | We present rigorous solutions for the geoid-fromquasigeoid
correction (GQC) using Taylor expansions of
surface gravity disturbances along the vertical from the
Earth’s surface to the geoid. One solution takes advantage
of the topographic potential bias at the geoid, which can
be expressed by a simple formula. This implies that the accurate
GQC does not need a terrain correction. |
