摘要 利用上海佘山站和乌鲁木齐南山站历年所参与的IVS联测数据进行了地球定向参数(Earth orienta-tion parameters,EOP)解算,结果表明,其精度与IERS EOP序列相当,两站单基线测定UT1的当前水平处于国际中等,但随着软硬件技术的发展,两站EOP观测精度在逐年提高。此外,2011年佘山站所参与的IVSUT1加强观测的UT1解算精度,以及两站参与国际EOP联测的解算精度都可以满足火星卫星百米量级定位精度对UT1的需求。 The EOPs are determined from the IVS observations which Sheshan Station in Shanghai and Nanshan Station in Urumqi were involved. The results show that the precision is comparable to the IERS EOP series, and the current precision of UT1 determined from single baseline observations of the two stations is in the middle level of the international. However, with the development of the technologies of software and hardware, the EOP pre- cision for observations of the two stations is improving year by year. Besides, the determina- tion preeisions of UT1 either from the IVS intensive observations in 2011 with Sheshan joint- ed in or from international EOP observations with the two stations jointed in, can meet the requirements of the 100-m positioning precision of satellite of Mars to UT1.
