geocentric coordinates

[¦jē·ō¦sen·trik kō′ȯrd·ən·əts]
(astronomy)
Coordinates that define the position of a point with respect to the center of the earth; can be either cartesian (x, y, and z) or spherical (latitude, longitude, and radial distance). Also known as geocentric coordinate system; geocentric position.

In these contributions, global horizontal and vertical movements were computed for individual tectonic plates from the velocity vectors published for the ITRF2000 by transformation of (X, Y, Z) geocentric coordinates and (dX/dt, dY/dt, dZ/dt) geocentric velocities to the ellipsoidal components: geographical latitude [phi], geographical longitude [lambda], ellipsoidal height H and their time derivatives (velocities) d[phi]/dt, d[lambda]/dt and dH/dt.
Detection of slight movements of monitored points at the Earth's surface is enabled by comparison of geocentric coordinates obtained at different epochs.
It is intended to include any relevant local or regional epoch networks into the permanent network frame if the solutions are available in form of geocentric coordinates and their covariance matrices.
