centimeter level accuracy. Location of sea-level changes using GPS and high precision measurement of the earth can reach centimeter-level accuracy.

GPS receiver is placed in the aircraft (aircraft, spacecraft, satellites, etc.) can be determined on the three-dimensional position and flight attitude. A variety of sea and air transport in particular the GPS auto navigation systems and management scheduling system, low-orbit communications satellite launch, the establishment of a global satellite navigation, positioning, communications Trinity system will shrink the world into a new electronic global village. In addition to measurement and military applications outside the traditional, GPS meteorology, GPS for the development of marine resources, tropical forests, fishing, grazing, tourism, adventure and a variety of disaster prevention and disaster reduction and so on. 

High-precision GPS technology has become the world's major countries and regions used to monitor volcanic earthquake, tectonic earthquake, global plate motion, particularly important means of plate boundary region. 

There are 200 global GPS reference stations, plans to tectonic plate boundaries and global activities in areas known to some 25 regional encrypted GPS monitoring network, the automatic global monitoring of crustal movement. In addition, together with the countries of the regional network, the main contents: 

• Research global relative motion between the plates; monitoring of tectonic plate boundaries and internal deformation; determine tectonic blocks of different scales scale movement pattern and movement rate.

Identify the regional displacement, velocity and strain field. 
