The crust movement of Asia Pacific area determined by the GPS data of APRGP97 and APRGP98
Abstract
Using the pseudo-nonfiducial position method of regional net, the GPS data of APRGP97 and APRGP98 by means of GIPSY and GAMIT softwares were treated. The formal coordinates obtained by us for most sites are 1 - 3 mm for north-south component, 2 - 5 mm for west-east component, and 5 - 10 mm for vertical component respectively. Moving velocities of about 50 sites in ITRF97 frame were also obtained, the uncertainties of which are about 1 - 4 mm/a.
