Impact parameter profile of synchrotron radiation
, 2004 The horizontal impact parameter profile of synchrotron radiation, for fixed vertical angle of the photon, is calculated. This profile is observed through an astigmatic optical system, horizontally focused on the electron trajectory and vertically focused

Precise Orbit Determination for ADEOS-II
, 2006 We performed the precise orbit determination of ADEOS-II using single frequency GPS data and reviewed the results. JAXA precise orbit determination system is called “GUTS (Global and high accUracy Trajectory determination system)”. In the 18th ISSFD, we reported that the accuracy of precise orbit determination achieved about 51cm.
