-
Scale:
Its scale is that of the local Earth frame, in the meaning of a relativistic theory of gravitation. Aligns with ITRS
-
Orientation:
Given by the Bureau International de l’Heure (BIH) orientation of 1984.0
-
Time Evolution:
Its time evolution in orientation will create no residual global rotation with regards to the crust
Coordinate System:
Cartesian Coordinates (X, Y, Z). WGS 84 (G1674) follows the criteria outlined in the International Earth Rotation Service (IERS) Technical Note 21. The WGS 84 Coordinate System origin also serves as the geometric center of the WGS 84 Ellipsoid and the Zaxis serves as the rotational axis of this ellipsoid of revolution. WGS 84 geodetic coordinates are generated by using its reference ellipsoid.
