摘要

摘要: 目的介绍了利用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。

Abstract: Objective The Chinese VLBI network(CVN)consists of four stations at Shanghai,Beijing,Kunmingand Urumqi,and are the VLBI tracking stations in the China’s Chang’e project.A solution schemewith 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 onthe four stations.Via a single session analysis and combined adjustment of single solutions,the coor-dinates and velocities for the Kunming and Beijing stations at the centimeter and millimeter per yearprecision are determined for the reference epoch J2000.0.Comparisons with the statistics from the a-dopted coordinates and velocities deduced in the Chang’e-1project show differences in coordinates ofup to 51.9cm,while the velocity varies up to 11.5mm/a,and are very significant.
