What is the ITRF?
In the late 1980’s with advances in space-based technologies (Satellite Laser Ranging, GPS, VLBI) a much more accurate spatial reference frame was determined, the ITRF (International Terrestrial Reference Frame). ITRF is a cartesian (X,Y,Z) system whose coordinates can be expressed both as (x,y,z) and lat/long and height above the GRS80 ellipsoid.
