摘　　要：乌鲁木齐天文站于 2 0 0 1年按照国家重大科学工程“中国地壳运动观测网络”基准站的要求 ,在乌鲁木齐南山站建立了GPS跟踪站 (GUAO :GPSstationoftheUrumqiAstronomicalObservatory) ,现已加入IGS网 ,并向IGS发送GPS观测资料。利用GAMIT软件 ,采用有基准算法对新建GPS跟踪站的观测资料进行了归算和精度分析 ,首次获得了该站在ITRF2 0 0 0中毫米级精度的地心坐标。In 2001, a new GPS tracking station was established on Nanshan site of the Urumqi Astronomical Observatory according to the specifications of the fiducial station required by the Chinese National Great Project 'Crustal Movement Observation Network of China'(CMONOC). The station is named as GUAO (GPS station of the Urumqi Astronomical Observatory). At present it joins in the IGS tracking station network and sends the tracking data to IGS once every day.By using GAMIT GPS observation reduction software and the fiducial positioning method, the tracking data of the newly constructed Nanshan GPS station of Urumqi Astronomical Station are processed. It is shown that the quality of the observation is reliable and the precision of millimeter level of geocentric coordinates of GUAO in ITRF2000 is achieved.
