广域星间单差快速收敛高精度电离层修正是非差非组合精密单点定位(precise point positioning,PPP)加速收敛的重要前提.首先基于参考站网台站观测数据,以非差非组合精密单点定位提取的电离层延迟作为建模数据源,提出一种基于多项式模型的估计天顶电离层延迟参数以及卫星硬件延迟的单差电离层模型.然后开发了服务端和用户端...
In the user PPP client, real‐time positioning using the broadcasted wide‐area VTEC parameters are performed.Results: Experiments using the GNSS network in the European region are performed, and results show that the internal RMSE (root mean squared error) and external RMSE of th...
