Because the capsule will reenter the atmosphere at night, it will appear as a bright light source during the high-heating portion of the trajectory. The present study describes the development of an operational capability to optically observe this part of the reentry capsule's descent through the atmosphere. The trajectory is estimated via an Extended Kalman Filter (EKF), using ground-based and/or aerial measurements of the capsule's angular position. The EKF is tested with simulations of the Hayabusa reentry, as well as NASA's Stardust reentry from 2006., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064734044}, pages = {269--276}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {TRAJECTORY ESTIMATION OF THE HAYABUSA SAMPLE RETURN CAPSULE USING OPTICAL SENSORS}, volume = {2009}, year = {2010} }
