Abstract: The Crustal Movement Observation Network of China (CMONOC) is 
one of the major scientific projects in China with its main aim of 
earthquake prediction and aims of scientific studies and geodetic 
survey. There are 25 fiducial stations, 56 basic stations, 1000 regional 
stations and a data center for the network. The construction of all 
observation piers was finished in mid 1998. The basic stations and 
fiducial stations were first observed from August 28 to September 7, 
1998 and the regional stations were first observed from March 10 to 
October 9, 1999. The fiducial stations have been in continuous operation 
since March 1999. In this paper, the Data Center is briefly introduced 
and the data processing and the results from the network are described. 
The observation data have been processed with the GAMIT/GLOBK software 
and Bernese software and GIPSY software will be used in data processing. 
Results from different software could be compared. With continuous 
observations at 25 fiducial stations, significant northward 
displacements were detected in the western part of China and southward 
displacements were detected in Yunnan in reference to stations in the 
eastern part of China. The crustal deformation in the network shows that 
China mainland is being pushed by the Indian plate.
