In order to efficiently analyze huge magnetic field data observed by satellites, we developed a routine analysis system to produce magnetic field data base for Japanese scientific satellites Akebono (EXOS-D) or Geotail, which carried triaxial fluxgate magnetometers. The magnetic field data are transformed from the magnetometer coordinate system to the inertial, geographic and topographic coordinate systems by using orbit data and attitude data. Since magnetic field data transformed by conversion of coordinate, depend on the accuracy of attitude data, raw attitude data are corrected automatically by choosing the best combination of attitude sensors in this system. Vector geomagnetic perturbations were obtained and 20 kinds of compiled results and graphs for scientific study as well.
