9 SHA: GNSS data analysis at SHAO  Infrastructure  Data and Analysis Center for CMONOC network: Daily routine for global GNSS network + CMONOC (Crustal Movement Observation Network of China)  Service

10 GPS/GLONASS Network GNSS network analyzed at SHAO

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

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

14 Coordinate time series PPP results from year 1999 to date

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