摘　　要：针对CGCS2000坐标系的启用,探讨了GPS数据中存在的坐标系统一问题,这些问题主要有:GPS基线向量坐标框架的统一、基线向量历元的统一、基线向量影响的量级分析和起算坐标的兼容性分析,并给出了相应的数学模型及适用条件。As CGCS2000 is opening, several technical problems for the coordinate systems unification in GPS data processing is studied. The problems consists of GPS baseline vector coordinate frame unifying, GPS baseline vector epoch unifying, baseline vector effect value analysis and compatibility analysis of starting point coordinates of GPS network, and moreover, several coordinate systems unification models is present.
