上海VLBI,SLR和GPS站站坐标的精密测定和精度估计

PRECISE DETERMINATION AND ACCURACY ESTIMATION OF SHANGHAI VLBI, SLR AND GPS STATION COORDINATES

本文对作为全球地球参考系基准站的上海VLBI，SLR和GPS站的站坐标进行了仔细的分析研究，并重新精密测定了SLR，GPS站的站坐标，给出了较可靠的精度估计。澄清了IERS的综合解所给出的上海SLR站站坐标存在的问题。

The geocentric coordinates of Shanghai VLBI,SLR and GPS stations to be as the fidu cial points of global terrestrial reference syetem, have been researched or redetermined, andthe reliable accuracy estimation of the station coordinates determined has also been rnade- Itbecome clear that there are rather too large in Shanghai SLR station coordinates published byIERS
