 note = {Localization is necessary for a planetary rover. Also for a rover on a small planet including asteroids and comets, precise localization is required. But usual positioning methods are useless on a small body surface. Localization by images obtained on-board needs the map which mother spacecraft made. But the accuracy of the map is not enough for the rover's view. Localization by celestial navigation needs a reference of standard direction. The gravity direction on earth passes the center of the mass. Contrarily, the gravity direction measured on a small body surface does not always pass the center of the mass because of the irregular shape. Thus, localization by celestial navigation does not satisfy the required accuracy. The velocity of on a small body surface is so small that it is hard to use Range Rate. It is not realistic to arrange navigation spacecraft near the small body planet like GPS (Global Positioning System). Thus there has been no efficient localization method over the small body surface. In this paper, we proposed an effective localization method of rover on a small body surface. Range measurement between rover and the mother spacecraft which use range measurement between a rover and a mother spacecraft. Formalization and simulation analysis are conducted. We processed the observed data by batch filter using least squares method. For real time localization, we used Kalman filter and its simulation result showed the efficiency of the proposed method., 資料番号: AA0063480017},
