所述基于igsrts数据的实时时间传递方法,首先获取igsrts的gps广播星历和gps轨道钟差改正数据,并计算卫星坐标和卫星钟差;再接收gps观测数据,采用gpsppp进行单站时间传递,解算出接收机钟差,计算两个测站的站间时差。本发明充分利用igsrts实时精密星历钟差数据的实时性强、精度高的优点,星历钟差改正信息数据更新率为1次/...
IGS Real-time Pilot Project’’ (http://.rtigs.net). In August 2011, the RTWG declared that the pilot project had reached the initial operating capability, providing access to continuous streams with GNSS data, precise orbit and clock corrections. IGS RTS has been officially launched on ...
IGS RTS provides real-time corrections via the Internet, intermittent data loss can occur due to software or hardware failures. We propose applying a genetic algorithm autoregressive moving average (GA-ARMA) model to predict the IGS RTS corrections during data loss periods. The RTS orbit and ...
The availability of IGS Real-Time Service (RTS) products makes Precise Point Positioning (PPP) a very powerful technique to process GNSS (Global Navigation Satellite System) signals in real-time. There are still, however, some limitations of PPP. A significant change in satellite geometry is requ...
