The use of GPS technology provides direct measurements of displacements due to plate motions and intraplate deformation, basic information for understanding kinematic of the movements. Using satelital geodesy techniques, crustal deformation rates in the southwestern Caribbean, southeastern of Central America and northwestern of South America wide plate boundary have been derived from GPS campaigns in 1988, 1990, 1991, 1994, 1996 and 1998 as part of the CASA (Central And South America) GPS Project. The zone of study includes the area of complex interaction between the Caribbean, Nazca and South America plates. The same GPS stations have been occupied with the purpose of making comparisons on the position of each site, analyzing distances of separation (baselines) and obtaining displacement vectors (magnitude and orientation). Some results are showed using the GIPSY -OASIS II software, that is a precision package for the analysis of GPS data developed by JPL-NASA. INGEOMINAS has built a GPS network called GEORED to be occupied succesively in order to get information about intraplate deformation, under the institutional project named Survey, Compilation and Generation of Geodynamics Information.
