GPS卫星应用于天球参考系连接之初探

THE PRELIMINARY STUDY OF THE GPS APPLICATION IN RADIO AND OPTICAL REFERENCE SYSTEM CONNECTION

本文论述了利用GPS卫星的射电与光学定位实现参考系连接的基本方法,并对参考系连接的精度作了分析。探讨了中国VLBI网利用GPS卫星进行参考系连接的可能性。文章认为以VLBI、CCD技术为观测手段,利用GPS卫星可使射电参考系与恒星参考系在0."01甚至更高的精度上得到连接。

The fundamental method about the use of GPS observations to connect the radio and optical reference systems by VLBI and optoelectronic measurements respectively is reviewed in this paper. Then the precision of the system connection with this method is discussed in detail. And the prossibility to do this project in China is also discussed. It is thought that the radio and optical reference systems will be aligned with accuracy below 0'.01 with the GPS observations by available radio and optical techniques.
