* x<math>_{CRS}</math> axis: Its origin is the geocentre, the Earth Centre of Mass, and its direction is towards the mean equinox at J2000.0 (i.e., the intersection between the J2000 equatorial plane and the ecliptic plane).

* z<math>_{CRS}</math> axis: This axis is defined by the direction of the earth mean rotation pole at J2000.0.

* y<math>_{CRS}</math> axis: Is the orthogonal to the formers ones, so the system is right handed.
