Gravity

Calculate gravity and magnetic fields for any point on Earth

Calculate gravity and magnetic fields using standards such as 1984 World Geodetic System, 1996 Earth Geopotential Model (EGM96), the World Magnetic Model (WMM), International Geomagnetic Reference Field, and Spherical Harmony Gravity. Download ephemeris data for the Geoid Height block using the aeroDataPackage function.
