摘要
采用均方根信息滤波(SRIF)方法,对IGS站实时观测数据进行了单历元解算,以便将卫星钟差等相关信息及时播发给用户,以进行实时精密定位。试验结果表明,GPS实时单历元解算的精密卫星钟差与IGS事后精密钟差相比,互差优于0.2ns,其精度与国际IGS各分析中心估计的卫星钟差精度相当。
Based on the PANDA software, the method of square root information filter （SRIF） is used by processing IGS stations real-time observation data and solving by model of single epoch. Broadcast the GPS clock information to the user. Hence, users can precise po sitioning in real-time. The results indicate that the differences of real-time precise clock from the IGS final precise clock products are better than 0.2 ns, which is the same accuracy level as those of all IGS analysis centers.
