ESTIMATION AND APPLICATION OF NEAR REAL-TIME SATELLITE CLOCK BIAS BASED ON REGIONAL CORS NETWORK
摘要
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 kinemat-ical accuracy of PPP is better than ± 1 cm in horizontal direction, ± 2 cm in the vertical direction.关键词
