Research on the Method of Calculating Gravity Disturbance Potential and Related Quantities with EGM2008 Model
The earth gravity field model EGM2008 provides the possibility of calculating global high-resolution and high-accuracy gravitational field related parameters. In this paper, the calculation steps and methods of gravity disturbance potential, gravity anomaly and geoid are studied and analyzed by using the spherical harmonic synthesis method, and the corresponding calculation program is compiled. The above parameters are calculated based on EGM2008 tide free model and zero tide model, and compared with the calcu-lation results of the calculation program issued by NGA, The correctness and reliability of the calculation method are verified.
