These are the model of the survey system for areas hit by natural disasters. The Kite-Plane has a solar panel (30 pieces of single junction GaAs solar cells) and receive the laser light. The laser diode we are using is a fibre-coupled type laser (lambda: 806.1 nm, output power: 200 W/cw, core diameter: 400 micrometer, NA: 0.22). The laser beam is focused about 33 cm diameter on the solar panel. The output power of the solar panel is about 40 W (laser output power: 300 W). The flight altitude is 50 m, and the circular flight radius is about 10 m. The kite-plane is tracked by the laser tracking system and receive laser beam. This tracking system is using a 4-element photodiode and a corner reflector. We have demonstrated the ability to use lasers as a source of power for the Kite-Plane at the Osaka Dome. The Kite-plane, which had a 30-minute test flight, used a battery to assist with take-off. (We have done a one-hour-flight before the demonstration in Osaka Dome.) 資料番号: AA0049121019 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) 2006-06 jpn conference paper https://jaxa.repo.nii.ac.jp/records/8085 第25回宇宙エネルギーシンポジウム　平成17年度 The Twenty-fifth Space Energy Symposium March 10, 2006 89 93
