摘    要:使用伪无基准(pseudo nonfiducial)算法、利用GIPSY软件,归算了APRGP97、APRGP98 和APRGP99的GPS资料.对大多数站所得解的站座标的精度:南北分量是1~2mm,东西分量是2~5mm,垂直分量是5~10mm;并初步获得亚太地区84个站在ITRF97中的运动速度,其水平方向的精度约为1~4mm/a.基于ITRF97速度场建立一个新的现今全球板块运动模型ITRF97VEL,由此获得这些站相对于该模型的现今形变速度,并对这些站相对欧亚板块的运动情况作了初步分析. 

关 键 词:GPS  地壳形变  板块运动  伪无基准算法

Abstract:Using the pseudo nonfiducial method of regional net, we have treated the GPS data of APRGP97, APRGP98 and APRGP99 by means of GIPSY software. The precision of coordinates obtained by us for most sites is 1~2 mm for north south component and 2~5 mm for west east component and 5~10 mm for vertical component, respectively. We have also obtained preliminarily moving velocities of 84 sites of Asia-Pacific area in ITRF97 frame. Based on the plate motion model derived from ITRF97, we have obtained the deformation velocity of the 84 sites relative to the plate in that they reside and preliminarily analyzed the motions of these sites relative to Eurasian plate.
Keywords:GPS  crustal deformation  plate motion  pseudo  nonfiducial
