Origin = Earth's center of mass
Z-Axis =
Parallel to the direction of the Conventional Terrestrial Pole (CTP) for
polar motion, as defined by the Bureau International de l'Heure (BIH) on
the basis of the coordinates adopted for the BIH stations.
Intersection of the W GS 84 Reference Meridian Plane and the plane of
X -Axis =
the CTP's Equator, the Reference Meridian being parallel to the Zero
Meridian defined by the BIH on the basis of the coordinates adopted for
the BIH stations.
Completes a right-handed, earth-centered, earth-fixed (ECEF)
Y -Axis =
orthogonal coordinate system, measured in the plane of the CTP
Equator, 90 East of the X -Axis.
