In orbit determination of a deep-space satellite, traditional radiometric data, that is, range and range rate data are used in most cases. 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.
