WebNov 1, 2024 · It reflects the absolute efficiency of solid earth tide and OTL correction. The range of Tx is 0.14–3.45 μgal using the best OTM. The ratios between Tx and M 0 ( Fig. 3 b) indicate that there are still tidal signals in the residuals at a significant level: the leftover tidal signals are above the observational errors.24 of the 35 stations ... Earth tide (also known as solid Earth tide, crustal tide, body tide, bodily tide or land tide) is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer. The largest body tide constituents are semi … See more The larger of the periodic gravitational forces is from the Moon but that of the Sun is also important. The images here show lunar tidal force when the Moon appears directly over 30° N (or 30° S). This pattern remains fixed with … See more The Earth tide encompasses the entire body of the Earth and is unhindered by the thin crust and land masses of the surface, on scales that … See more Seismologists have determined that microseismic events are correlated to tidal variations in Central Asia (north of the Himalayas); see: tidal triggering of earthquakes. … See more • Love numbers See more In coastal areas, because the ocean tide is quite out of step with the Earth tide, at high ocean tide there is an excess of water above what would be the gravitational equilibrium level, and therefore the adjacent ground falls in response to the resulting … See more Body tides also exist in other astronomical objects, such as planets and moons.

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.
