〜WASP〜 Waseda Satellite Project WASEDA-SAT2 概要 プロジェクト概要  メンバー紹介  最新情報  お問い合わせ  リンク  QRコード募集
　　　WASEDA-SAT2 is the satellite that was designed and developed by MIYASHITA and YAMAKAWA laboratories.This satellite is selected as one of the small sub-satellites ridden together at the launch of Venus probe "PLANET-C" which the launch is scheduled for May, 2010 by Japan Aerospace Exploration Agency (JAXA).

　　　The mission of this satellite is the examination whether the posture of this satellite can be stabilized by air resistance that is generated by the expansion of panels or not, and doing a basic experiment about the data communications technoogy between optical satellites using the verification whether the posture of the satellite can be stabilized according to the obtained the QR-code.

　　　In the examination whether the posture of this satellite can be stabilized or not, an acceleration sensor is installed on the inside of the satellite and we judge that by the data of acceleration received from the satellite.

　　　In the basic experiment about the data communications technoogy, first, the QR-code is displayed on the LED panel. Second, this code is taken a photograph by the camera. Then, the data of this code is transmitted by the electric wave. Finally, we display the QR-code on the homepage.

　　　At this launch, the orbit altitude that WASEDA-SAT2 go into is low, so this satellite will rush into the atmosphere in several weeks. To the success of the mission, we need to take data efficiently from this satellite during the short time. So, we got a license as amateur satellite which can be cooperated by many eager satellite enthusiasts.

　　　Many of amateur satellite use 144MHz band for uplink, 430MHz band for downlink. Although it's thought that it will be promoted that utilization of microwave band aftertime, it have possibilities to be developed satellites using low-frequency band like 29MHz band, and in that case, it is assumed that such a satellite decomes tether satellite because of structual restrictions about antenna and translator. We think that an optical satellite communication becomes effective in such a satellite.

　　　The missions of WASEDA-SAT2, as part of education and research of university, are done by studentsbecause we contribute to the rearing of the talented people who become leaders in the next generation of the development of the space satellite.
