摘　　要：介绍了利用OCCAM软件处理中国VLBI网(CVN)4台站常规天体测量与大地测量观测资料的解算方案,包括参数设置、模型选取和数据编辑等。通过单次实验解算和联合平差,获得了ITRF2000下参考历元J2010.0时昆明和北京站cm级的站坐标及mm级每年的站速度。解算值相对于嫦娥一号工程期间采用值的推算值,坐标改正最大至51.9cm,速度改正最大至11.5mm·a-1。The C and Urumqi, an hinese VLBI network （CVN） consists of four stations at Shanghai, Beijing, Kunming d are the VLBI tracking stations in the China＇s Chang＇e project. A solution scheme with the software OCCAM including the settings of parameters, the selection of models and the edi- tion of observations is introduced to analyze the astrometric and geodetic VLBI with experiments on the four stations. Via a single session analysis and combined adjustment of single solutions, the coor- dinates and velocities for the Kunming and Beiiing stations at the centimeter and millimeter per year precision are determined for the reference epoch J2000.0. Comparisons with the statistics from the a- dopted coordinates and velocities deduced in the Chang＇ e-1 project show differences in coordinates of up to 51.9 cm, while the velocity varies up to 11.5 mm/a, and are very significant.
