【摘要】 为了响应国际地球自转服务中心(IERS)和国际激光测距服务中心(ILRS)的呼吁,上海天文台天文地球动力学研究中心参加了对激光测距卫星lageos1、lageos2的资料的分析、计算,提交了关于地球定向参数(EOP)(1998-2001)的联合(lageos1、lageos2)解算结果报告:(SHAO)2002 L 01 利用更精细化的和改正了的计算EOP的模型,获得了EOP(SHAO)2002 L 01系列。该系列与同时期的IERS的EOP(IERS)C04相比,符合程度:极移X_p、Y_p好于0.35mas,日长变化D_u好于0.030ms。更多还原

【Abstract】 As a reponse for the appeal of International Earth Rotation Service (IERS) and International Laser Ranging Service (ILRS), Center for Astro-Geodynamical Research, Shanghai Astronomical Observatory (SHAO) processed the combination of analyzing and computing Satellite Laser Ranging (SLR) data of lageosl and Iageos2 in the determination of Earth Orientation Parameters (EOF). SHAO submitted the report with respect to EOF between 1998 and 2001 combining lageosl and Iageos2: (SHAO) 2002 L 01, in which the process, the model computing EOF was updated and refined.The series was compared with EOF (IERS) C 04 at the same time. The goodnesses of them are respectively: Xp and Yp are superior to 0.35 mas, Length of Day (LOD) is superior to 0.30ms.更多还原
