ESTIMATION AND APPLICATION OF NEAR REAL-TIME SATELLITE CLOCK BIAS BASED ON REGIONAL CORS NETWORK
基于区域CORS网的卫星钟差准实时估计及其应用

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.
