It is expected that an orbit transfer vehicle using an ion thruster (IOTV) can obtain a large payload ratio, because the ion thruster has a high specific impulse (several thousands seconds). However, orbit transfer missions by means of the IOTV require large trip times, therefore it is necessary for the ion thruster to have a sufficient endurance performance. In this study, the trajectory of the solar powered IOTV was analyzed in consideration of the influence of earth's eclipse, then the payload capability of the IOTV and the steady/endurance performance of the ion thruster were evaluated. For results, it was found that the IOTV could achieve approximately double the payload mass of the OTV using a chemical rocket, and a required durability to the ion thruster was comparable to one that has used for ETS-VI.
