Embodiment Construction
[0075] With the accumulation of oceanographic observation data and the development of space geodetic technology, the accuracy and resolution of mean sea level height and ocean geoid have been continuously improved; value) has also been continuously improved. Due to the short distance between virtual stations (usually set to a few kilometers, determined by the resolution of the ocean gravity field), the sea topographic observations at adjacent stations are almost equally affected by various error factors, so the difference is used instead Leveling height difference observation is theoretically feasible. On the other hand, on land, although the precise geometric level can reach millimeter-level accuracy, the topography of the point to be measured has large fluctuations, and the average gravity value on the vertical line between it and the geoid is related to the crustal density below the point to be measured. It can neither be measured nor calculated accurately, and usually can...
