2. THE SPATIAL TECHNOLOGY- GPS
Spatial geodetic technology opened up a brand new way for the current monitoring crustal movement,
especially the GPS technology, with its observation of high precision, small size equipment, operating
efficiency fast, not-as between stations, all-weather advantages etc., has brought revolutionary change for
monitoring the global and regional crustal movement. Using GPS to study crustal movement and explore
geodynamic phenomenon in the world were developing rapidly, the application of GPS in geodesy, geophysics,
geology, and other field, was more extensive, and the application of GPS observing technology were
increasingly learning of the broad masses of workers to the attention.
