2 2 Content  CMONOC Network  GNSS Analysis Center at SHAO  GNSS Results

3 3 CMONOC network Crustal Movement Observation Network of China Motivation:  Tectonic & Geodynamic  Earthquake monitoring & Alert  Natural hazards  Geodesy  Military surveying  Civil use

4 4 CMONOC network Pioneer project, Phase I: since 1997 VLBI: 3 SLR: 5 GNSS: ~31 continuous + >1000 campaign sites Follow-on, Phase II: since 2008 VLBI: 3+1 SLR: 7 Gravity Stations: 30 Permanent Relative+ ~ 100 Campaign Absolute GNSS:~260 continuous + > 2000 campaign sites Crustal Movement Observation Network of China In addition, more than 300 local CORS GNSS stations

5 5 Chinese VLBI network Sheshan(SHAO):25m Urumqi:25m Kunming:40m Beijing:50m Sheshan, Urumqi contribute to IVS Data analysis center located at SHAO Wang G. SHAO

6 6 Distribution of the Chinese SLR station Zhang Z. SHAO

7 7 CMONOC network analyzed at SHAO CMONOC GNSS network

8 8 CMONOC network analyzed at SHAO CMONOC GNSS network

9 9 SHA: GNSS data analysis at SHAO http://www.shao.ac.cn/shao_gnss_ac  Infrastructure  Data and Analysis Center for CMONOC network: Daily routine for global GNSS network + CMONOC (Crustal Movement Observation Network of China)  Service

10 10 GPS/GLONASS Network GNSS network analyzed at SHAO

11 11 Products of SHA: e.g. GNSS orbits GNSS Orbits  GPS+GLONASS  Compared to IGS  <2 cm for GPS; <5 cm for GLONASS

12 12 Products of SHA: e.g. GNSS clocks GNSS clocks: 30 seconds  GPS+GLONASS  Compared to IGS  <0.05 ns for GPS; <0.15 ns for GLONASS

13 13 GNSS Results  Tectonic study  Coordinates time series  Velocity field  Events Monitoring  Troposphere  Ionosphere

14 14 Coordinate time series PPP results from year 1999 to date

15 15 Velocity field Based on 4 month data; whole map (>200 stations, longer than 1 year ) to be released

16 16 Events monitoring  2008,05,12, Mw 7.9 Wenchuan earthquake in Sichuan Province,China  Kinematic solution (a set of coordinates at each 1 second)  Station XANY,~600 km from epicenter Coseismic monitoring

17 17 Events monitoring Atmosphere monitoring (Rainfall)  Real-time epoch-wise analysis to derive Troposphere parameters  Modeling of Troposphere parameters  Evaluation of the derived models

18 18 Events monitoring Atmosphere monitoring (Rainfall)  Real-time epoch-wise analysis to derive Troposphere parameters  Modeling of Troposphere parameters  Evaluation of the derived models

19 19 Events monitoring Atmosphere monitoring (Rainfall)

20 20 Events monitoring Atmosphere monitoring (Tomography)

21 21 Events monitoring Atmosphere monitoring (Storm)

22 22 Events monitoring Atmosphere maps(Ionosphere)  Real-time epoch-wise analysis to derive Ionosphere parameters  Modeling of Ionosphere parameters  Densification of Ionosphere model

23 23 Events monitoring Atmosphere maps(Ionosphere)  Real-time epoch-wise analysis to derive Ionosphere parameters  Modeling of Ionosphere parameters  Densification of Ionosphere model

24 24 Events monitoring Atmosphere maps(Ionosphere)

25 25 Events monitoring Atmosphere maps(Ionosphere)

26 26 Events monitoring Atmosphere maps(Ionosphere)

27 27 SHA: GNSS data analysis at SHAO http://www.shao.ac.cn/shao_gnss_ac  Routine CMONOC Data Analysis  Time series for all stations  Towards real-time monitoring
