WebAug 21, 2024 · One way to find e ^ is to project p onto the equatorial plane, normalize it to unit length, and rotate it 90 degrees eastward. If p = ( x P, y P, z P) then e ^ = 1 x P 2 + y P 2 ( − y P, x P, 0). 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.
