摘　　要：随着全球参考框架的日趋成熟,ITRF参考框架在大地测量学和地球动力学方面的作用也越来越重要。常规地面测量成果或是属于国家的参心大地坐标系,或是属于地方独立坐标系,而GPS定位结果属协议地球地心坐标系,即WGS?84坐标系。因此必须实现GPS成果的坐标系的转换,以便将GPS成果更好的应用于我们的国民生产和实践之中,这就存在一个坐标的转化问题。本文就它们之间的转换提出具体的转化模型,求得转换七参数并应用于实例,获得了很好的转换结果。Along with the maturation of globle reference frame, ITRF reference frame is more and more important in geodesy and geodynamics. The production of the general survey belongs to either the national geodetic coordinate system or the regional independence coordinate system, but the result of GPS survey- belong to the protocol global coordinate system - - WGS - 84. So the GPS coordinate must be transformed to make the result of GPS survey used in the country production. The specific conversion model is proposed in this paper. And the seven-parameter applied to the practice is calculated. A perfect conversion result has been gotten.
