Data processing and accuracy evaluating of velocity field of APRGP

WANG Hua1,CHENG Peng-fei1,CHENG Ying-yan1,LAN Li2 (1.Chinese Academy of Surveying and Mapping,Beijing 100039,China;2.Yulin Municipal Bureau of State Land and Resources,Yulin 537000,China)  
The theory and methodology of data processing of wide area high-precision GPS networks-Asia Pacific Regional Geodesy Project(APRGP) are discussed systematically in this article.With the updated software BSE5.0,the annual results of APRGP coordinates and velocity field were computed again,also the corresponding accuracy of different constraints for adjustment were presented here.Velocity field of Asia-Pacific region was analyzed and compared with that of IGS,and the velocity of APRGP agrees with that of IGS was concluded in the article.
