WebVectors represent quantities such as velocity and acceleration. Mapping Toolbox™ functions transform vector components between Earth-centered Earth-fixed (ECEF) and east-north-up (ENU) or north-east-down (NED) systems. For more information about ECEF, ENU, and NED coordinate systems, see Comparison of 3-D Coordinate Systems. WebMar 12, 2024 · This, to me, implies that the satellite reference frame remains aligned with the ECEF frame, because an "offset" is typically a linear displacement. (An angular displacement is a "rotation"). If this is the case, then the basis vectors are the same for both the ECEF and the satellite reference frame, and a vector in ECEF is converted to ...

Two different coordinate frames are generally employed: the Earth-centered, Earth fixed (ECEF) frame, which is non-inertial; …
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 … 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 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 See more • Earth-centered inertial (ECI) • Geodetic system • International Terrestrial Reference System and Frame (ITRS) See more WebJan 4, 2024 · [r_eci,v_eci,a_eci] = ecef2eci ( ___,Name,Value) calculates the position, velocity, and acceleration vectors at a higher precision using Earth orientation parameters.

WebMar 27, 2024 · You can get the rotation matrices from J2000 to ECEF using SPICE, specifically SPICE's pxform function. Someone else asked about this same topic in another question here ( Is it posible to convert JPL Horizons Vectors to ECEF?) where I showed which SPICE kernels to use in order to calculate ECEF vectors at given times.
