The coordinate reference datum on which precision GPS survey is based, is ITRF International Terrestrial Reference Frame that IERS offers. The various periods' ITRF frames have systemic error including translation, length scale and rotation. In processing GPS data, applied coordinate datum of terrestrial station should be transformed to united ITRFyy frame and epoch. In this paper author deals in detail with united method of coordinate datum in GPS surveying.
