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
