The International Terrestrial Reference Frame is the reference system based on the ITRS. Its origin is at the center of mass of the whole Earth (including atmosphere and oceans). New ITRF solutions are produced every few years with slight variations, to improve the system to be as precise as possible. Its EPSG code is EPSG:7789.
