　　ERP (Earth Rotation Parameters) means the parameters of the change of the Earth rotation speed (UT1-UTC) and polar coordinates(xp,yp).Currently, IERS (International Earth Rotation Service Organization) and data processing centers of IGS (International GNSS Service) are involved in the maintenance of the global coordinate reference system and release of the Earth rotation parameters.IERS use LLR, SLR, VLBI, Doris and GPS measures and calculates parameters of the Earth rotation which has reached the accuracy of subcentimeter, an ERP solution per day.
