PRISM Operation Real Time Report

This blog is written by "EUC-JP" encode.
When you use another encode, text written by Japanese will be garbled.
But we put down same contents with English, so try to find in "Category" on the left column and enjoy.
Sorry to put you to the trouble.

Three days have passed since PRISM was launched.

These days sometimes seemed very short for us, but also sometimes seemed very long.
Anyway, however, it was a very precious time.
We deeply appreciate the warm heart of everyone who has supported us, without anyone of whom, we not could not have had such magic hours.

But the true satellite project begins after it was launched.
We will continue to make an effort from now on toward the aim to achieve the imaging mission and to open up a new page of picosatellite development,

As the satellite project has moved into its operation phase, this blog, "PRISM Operation Real Time Report," will also finish its role.
The future operation information will be updated on the web page of the ISSL Ground Station and If we will plan to do important operation events, we will publish on the main web page of PRISM too.
Please check them.

Finally, thank you very much again for your support!
Please keep on watching PRISM warmly.

PRISMが打ち上げられてから３日。

それは、仕事に忙殺されたあっという間の３日間だったと同時に、
もう打ち上げ日はとうの昔な気がしてくるほど、長い３日間でもありました。
こんな魔法のような時間を与えてくださった、開発にたずさわった皆様、打ち上げにたずさわった皆様、さまざまな方面から支えてくださった皆様、そして応援してくださったすべての皆様に深くお礼を申し上げます。

さて、衛星は打ちあがってからが本番。
これから運用班一同、撮像ミッションの達成、そして小型衛星の新たな１ページを切り開くという目標に向けて、努力していきたいと思います。

つきまして、この実況中継ブログはひとまず役割を終えたこととし、今後の運用報告は東京大学中須賀研究室地上局ウェブサイトをご参照ください。
また、大きな運用イベントが計画された場合はPRISMウェブページにも更新をしていこうと思いますので、チェックをよろしくお願いします。

あらためて、ここまで応援してくださって、本当にありがとうございました。
これからもどうか暖かい目でPRISMを見守ってあげてください。

Battery data and communication data shortly after the release are being acquired.

current value of secondary batteries (C:charge, D:discharge)
The peak of charge current are decreasing, so energy balances is positive.


Voltage of solar batteries
It looks like cyclic.


Voltage of secondary batteries:


temperature data:
panel's temperature is much lower then we have thought but it is not problem.


Gyro data:
Inertia moment of Z axis is larger than other two axises.
But PRISM dose not have mechanism of energy release, so rotation around Z axis is relatively stable.


current of solar battery of each aspects:
SAB is on body mount, SAN is on panels of body side, SAP is on panels of oppositional body side.
