So as to verify the system compatibility between the orbital design and the spacecraft capability, antenna elevation in the first visible pass from UDSC (Usuda Deep Space Center) and shadow duration of the elliptic orbit about Venus are evaluated in this paper. Required velocity amount for orbit and attitude correction is also estimated for the 2010 launch orbit. Currently, three weeks in total of launch possibilities, one week in May and two weeks in June 2010, are ensured for the PLANET-C mission., 資料番号: AA0063480014}, pages = {86--91}, 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/ISAS)}, title = {Orbital characteristics of Venus explorer, PLANET-C}, year = {2006} }
