Abstract By using the undifferenced ionospherefree model,the realtime satellite clock is estimated based on regional GPS continuously operating reference stations (CORS) data and IGU predicted orbit and then the realtime clock is respective compared with IGS final product and applied to the realtime PPP. The experimental results show that the accuracy between the estimate clock bias and IGS final product is better than ±0.2 ns, the kinematical accuracy of PPP is better than ±1 cm in horizontal direction, ±2 cm in the vertical direction.
