The Group of GNSS Data Analysis and Applications at SHAO (GGDAA)  was established early 2011. Shortly after the setup of the GGDAA, we start the IGR-like GNSS data analysis using GNSS data from the global network together the Crustal Movement Observation Network of China (CMONOC) network. After a period of experimental operation, the system is in routine operation with good stability and precision. Our products have been utilized and acknowledged in many key space programs of China.

The ongoing tasks and activities of GGDAA are:

(1)Data analysis and products evaluation of the CMONOC network

(2)Data analysis and products provision of the IGS network

The GNSS data analysis at SHA is the integrated GNSS solution [Presentation at IGS Bias Workshop 2012] with products presented in the same ITRF reference frames. In particular, the GLONASS satellite clocks are in the same time frame as GPS, aligned to GPS broadcast (GPST). Both GPS and GLONASS clocks are provided with a sampling of 30 seconds.

We are working towards:

(1)Multi-GNSS data analysis (IGS M-GEX)  [Further results: Presentation at IGS Workshop 2012 in Poland]

(2)BeiDou/Compass data analysis [Presentation at IGS Bias Workshop 2012]
