Shinshu-made ultra-compact satellite "ShindaiSat"

Assembly "ShindaiSat (bed Sat)" of (nickname, Silver Mountain) Shinshu made ​​by ultra-small satellites scheduled to be launched in 2013 fiscal year has been completed, 26, prefectures supplies and parts in Shinshu Univ Faculty of Engineering campus in Nagano Wakasato it was unveiled to the company officials inside and outside. It is expected that through the performance test, and deliver Japan Aerospace Exploration Agency to (JAXA) at the end of November.
Cube of about 40 cm on a side satellite (about 35 km). 32 a light emitting diode (LED) is used to communicate with the ground, it has been installed solar cell power generation side (4 surface) at the top of the outer surface. I incorporating such as power and device for attitude control in space inside.
Received the parts supply companies from outside the prefecture, graduate students and others Nakajima, Professor of university had assembled from the end of August. Make sure you use performance test in a vacuum state after completion, to operate normally. To continue the test or is it successful if vibration or shock in the future.
Satellite was launched in the H2A rocket, I orbiting 400 kilometers above ground. Is performed each other to receive an LED emit light each other on the ground between the satellite the "visible light communication experiment", and make sure the utility of visible light communication ultra-long distance, to explore the possibility of new means of communication. Is that you can experiment before and after 1 year.
Nakajima Professor is expected to launch in February next year around, it is said, "you can confirm the performance of the satellite, and you want to or establish a communication device of the ground in the future" he said.

I hope that you have the performance confirmation of the last, to be launched as scheduled. I want you to show the results to show the height of the technology of Shinshu.


２０１３年度内に打ち上げられる予定の信州製超小型人工衛星「ＳｈｉｎｄａｉＳａｔ（シンダイサット）」（愛称・ぎんれい）の組み立てが完了し、長野市若里の信州大工学部キャンパスで２６日、部品などを供給した県内外の企業関係者らにお披露目された。性能検査を経て、１１月末に宇宙航空研究開発機構（ＪＡＸＡ）に引き渡す予定だ。
　衛星は一辺約４０センチの立方体（約３５キロ）。外面の上部には地上との通信に使う発光ダイオード（ＬＥＤ）を３２個、側面（４面）には発電用の太陽電池を装着している。内部には宇宙空間で姿勢制御する装置や電源などを組み込んだ。
　県内外の企業から部品供給を受け、同大の中島特任教授や大学院生らが８月下旬から組み立てていた。完成後に真空状態で性能試験し、正常に作動することを確認。今後は振動や衝撃を与えても正常に作動するか試験を続ける。
　衛星はＨ２Ａロケットで打ち上げられ、地上４００キロの軌道を回る。衛星と地上間で互いに発光させたＬＥＤを受信し合う「可視光通信実験」を行い、超長距離の可視光通信の実用性を確かめ、新たな通信手段の可能性を探る。１年前後は実験できるという。
　中島特任教授は来年２月ごろの打ち上げを見込んでおり、「今後は衛星の性能を確認したり、地上側の通信機器を整備したりしたい」と話している。
　最後の性能確認等を行って、予定どおり打ち上げられることを期待します。信州の技術の高さを示す結果を示して欲しいですね。
