This paper is described Earth-based orbit determination capability for the low-thrust spacecraft in the light of recent developments both in a few station tracking concepts and in the thrust subsystem error modeling. Both suboptimal and optimal orbit determination performance are determined for a wide range of process noise parameter values. The tracking techniques are found to be extremely effective, reducing orbit determination errors by orders of magnitude over that obtained with conventional single-station tracking., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064733051}, 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 = {低推力下での軌道決定についての一考察}, volume = {2008}, year = {2009} }
