Determination and Analysis of Station Parameters ofthe Chinese VLBI Network

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.
