Aiming at precise orbit determination of a geosynchronous satellite, a VLBI experiment was conducted to observe the 2GHz band telemetry signal of the DSCS-II satellite stationed at 180deg, East. A differential VLBI method was used, where the satellite and quasars with well-known positions were alternatively observed over 24 hours using stations in Japan, United States and Australia. It was confirmed that a few meter position accuracy of the satellite in an inertial frame referring to the quasars was achieved in orbit determinations and covariance analysis considering observation errors, quasar position errors, and modeling errors in the observation system and satellite dynamics.
