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.

WebEarth and Moon have the most number of supported systems (the Moon has many different versions of the Fixed system); the Sun includes ecliptic-based frames; other central bodies have a generic set of systems. There are two classes of coordinate systems: fixed and inertial. Fixed systems nominally rotate with the central body’s topography: 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 ... WebIt is really true; ECEF is a specific coordinate system.
