Earth centered inertial coordinate
WebEarth-Centered Inertial (ECI) Frame. The earth-centered inertial (ECI) frame is a global reference frame that has its origin at the center of the Earth. This reference frame does not rotate with Earth and serves as an inertial reference frame for satellites orbiting the Earth. Due to this, the ECI frame is used primarily in space applications. WebCoordinate frame in which the outputs are returned, specified as 'inertial', 'ecef', or 'geographic'. The 'inertial' option returns the position and velocity coordinates in the GCRF. The 'ecef' option returns the position and velocity coordinates in the ECEF frame. For more information on ECEF frames, see Earth-Centered Earth-Fixed Coordinates.
