A Novel Rapid GNSS Network Solution in Mountainous Region Monitoring considering the Tropospheric Delay at Ground Points

Scheme 2

All stations carry out tropospheric delay estimation. The dry component of the Saastamoinen+Vienna mapping functions 1 (VMF1) model is used as the priori value. The wet component of the tropospheric delay is estimated at all stations. The tropospheric parameters are linearly modelled, so that each period includes the number of the station parameters for the tropospheric delay.
