Evaluation of the accuracy of the global gravity models EGM2008 and GAO2018 by geometric method taking in account different tide systems
The article deals with the issues of evaluation of Earth’s global gravity field models based on a set of points within the borders of the Republic of Belarus, taking tide effects into account both in regard to Earth’s surface geometry parameters, and to gravity field parameters. Accuracy evaluation of studied geopotential models is performed, tide system corrections are shown.
