| Abstract: | By using the un-differenced ionosphere-free model,the real-time satellite clock is estimated based on regional GPS continuously operating reference stations(CORS) data and IGU predicted orbit and then the real-time clock is respective compared with IGS final product and applied to the real-time 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. |

| Keywords: | un-differenced real-time precise point positioning(PPP) satellite clock bias regional GPS continuously operating reference stations(CORS) network |
