Since these data have sensitivity in line of site direction, orbit determination accuracy is good in this direction, but there is less accuracy in perpendicular directions. On the other hand, VLBI data have sensitivity perpendicular to the line of site direction, so the combination of traditional radiometric data and VLBI data are very effective to improve the orbit determination accuracy. In this paper, the orbit determination analysis is carried out by using VLBI observation data, and some typical results for ISAS deep-space satellites are shown., 資料番号: AA0045497007}, pages = {39--44}, publisher = {宇宙科学研究所, The Institute of Space and Astronautical Science (ISAS)}, title = {Orbit determination analysis using VLBI observation data}, year = {2003} }
