On Local Deflections of the Vertical Based on EGM2008 and In Situ Data
The Earth gravitational field model EGM2008 with the high resolution has been applied in data processing and analysis in practical geodetic and geophysical study. We calculate the deflection of the vertical on testing areas in China from EGM2008 with the different grids based on the geopotential theory. What’s more, the precisions of the deflection of the vertical determined with EGM2008 up to different degrees and orders are compared and analyzed by calculating the actual astro-geodetic data and modelled data to evaluate the regional quality of EGM2008 with in situ data. Precisions of meridian and prime vertical components of vertical deflections estimated with EGM2008 up to 2190 degrees are 1.59″ and 1.74″, respectively.
