Comparison and Accuracy Estimation of Modern Models of the Earth’s Gravitational Potential

Comparison and Accuracy Estimation of Modern Models of the Earth’s Gravitational Potential

The paper presents a brief overview of new models of the Earth’s gravitational potential constructed based on satellite-to-satellite tracking, satellite gradiometry, satellite altimetry, as well as ground gravimetric and satellite laser ranging. Inherent accuracy estimation of the described models a...
