The spherical harmonic gravity model is valid for radial positions greater than the planet equatorial radius. Minor errors might occur for radial positions near or at the planetary surface. The spherical harmonic gravity model is not valid for radial positions less than planetary surface. Tips WebIn this project, a functon for MATLAB has been developed to compute Earth's gravitational acceleration using EGM-2008 gravity model. The function works 8 to 10 times faster comparing to ‘gravitysphericalharmonic’ function of Aerospace toolbox of MATLAB when tested in MATLAB R2024a and using 120 degree and order of EGM-2008.
