Abstract: The CPF ephemeris is currently used for the prediction of the satellite orbits in SLR.The precision ephemeris of 5 satellites are used to assess the CPF ephemeris accuracy. The CPF ephemeris which predicts a 5-day period of the orbits of GPS36 provided by CODE has an accuracy of 2 meters,and the 5-days CPF prediction accuracy of LAGEOS- 1 and Ajisai is less than 2 meter.On the other hand,the 1-day prediction accuracy of non-spherical satellite,such as Envisat and Jason-1,is a few meters,and some providers' prediction is worse.
