Web5.02.2.1.1 Geodetic and geocentric coordinates and components. Since spherical components (and coordinates) are used for geomagnetic field modeling, it is necessary to transform the locations of surface data, and the data themselves, from the geodetic to the geocentric coordinate system. This can be done in the following way: Web5.02.2.1.1 Geodetic and geocentric coordinates and components.

WebApr 10, 2024 · The geocentric-equatorial coordinate system uses the center of the earth as the origin, and uses the circle of the Earth's equator as the fundamental plane with the positive vertical axis is the north pole of the earth. Two different coordinate frames are generally employed: the Earth-centered, Earth fixed (ECEF) frame, which is non-inertial; … Just as the two-dimensional Cartesian coordinate system is useful on the plane, a two-dimensional spherical coordinate system is useful on the surface of a sphere. In this system, the sphere is taken as a unit sphere, so the radius is unity and can generally be ignored. This simplification can also be very useful when dealing with objects such as rotational matrices.
