The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its … See more As with any spatial reference system, ECEF consists of an abstract coordinate system (in this case, a conventional three-dimensional right-handed system), and a geodetic datum that binds the coordinate system to actual … See more • ECEF datum transformation Archived March 22, 2007, at the Wayback Machine Notes on converting ECEF coordinates to WGS-84 datum • Datum Transformations of GPS Positions Application Note Archived September 27, 2007, at the Wayback Machine Clearer … See more Geocentric coordinates can be used for locating astronomical objects in the Solar System in three dimensions along the Cartesian X, Y, and Z axes.

WebThe satellite position and velocity in the Earth-Centered Inertial (ECI) [3], [7], [8] coordinate frame are then extracted and projected to the 3D environment. Furthermore, the ECI position is ... Earth-centered inertial (ECI) coordinate frames have their origins at the center of mass of Earth and are fixed with respect to the stars. "I" in "ECI" stands for inertial (i.e. "not accelerating"), in contrast to the "Earth-centered - Earth-fixed" (ECEF) frames, which remains fixed with respect to Earth's surface in its rotation, and then rotates with respect to stars.

The most famous, of course, is ICRS, based on directions to many distant celestial bodies, but you can create an ECI coordinate system at any moment in time just by picking your 3 axes in an inertial frame and leaving it at that.
