The first Japanese Lunar swing-by spacecraft called 'HITEN' was launched from Uchinoura launching site, located at about l, 500km south-west of Tokyo, respectively on January 25,1990. The four-stage solid propellant boosters called M3SII-V for this purpose. The spacecraft successfully performed first lunar swing-by in March 18,1990. Tracking and orbit determination of the spacecraft have been smoothly carried out throughout this period using Usuda 64φ antenna. The major hardware modification for Usuda 64mφ antenna is the introduction of X band ranging and range-rate system (down link). As for the range-rate data, higher precision can be expected, at least theoretically, because of higher frequency than S band signals. In preparing for this mission, the software package ISSOP developed for 'SAKIGAKE' and 'SUISEI' mission in 1985 had been modified. The improvements were added to the rejection scheme of poor data, computation of the light-time equation and troposphere and ionosphere correction. In this report the structure and the improvements of ISSOP is first described. Then the result of orbit determination of 'HITEN' is discussed. In the future, this software package will be modified and used 'GEOTAIL' mission in 1992.
