GNSS Data Processing with Mixed Single and Dual Frequency Receivers for High Accuracy Near Real-time Weather Monitoring

Here we introduced a new kind of ionospheric model(SEID),and it is adapted for near real-time weather monitoring based on the characteristics of data processing for large network.The effects of this strategy in different size of reference network have been studied through serial analysis of a example of SXCORS.For reference network with averaged separation shorter than 249 km in Shanxi Province,we can gain regional PWV within 1~2 mm using single frequency observations.
