[CanSat Introduction]
The SPROUT-CAN team launched the OpenClass model for experiment. The mission of SPROUT-CAN is to acquire the technology of SSTV(Slow Scan Television) is installed in SPROUT for the next term following CubeSat SEEDS of Nihon University. SPROUT-CAN takes a picture in the sky with CMOS camera after it is released from the rocket, and adds an original logo to the image data. And, It is converted into the voice data of SSTV, and the transmitter sends it. One image every 200 seconds is sent by the mode "Martin 1" that spends 114 seconds.
[Approach and solution]
A substantial development period is two months. We managed tightly schedule like the long distance communication test, the balloon test, and the vibration test, etc. We stayed at the laboratory for one week occasionally. Therefore, flight model 1 was able to leave Japan in the state only flight. However, the camera of flight model 2 did not work normally, and it went like crazy in the hotel.
The handling of the flight model is very careful from making boards to the body and we are proud of the beautiful form to say nothing of contents.
[Result]
First day, the line of parafoil was twisted and SPROUT-CAN spiraled. Though one image of SSTV was able to be received, the prop of the body bent and the board of C&DH cracked. Second day, we tried to launch the flight model 2. Moreover, we judged it was reckless to use the parafoil in the strong wind, so we bought the parachute and installed. However, we abandoned the launch because of the too strong wind. Then, we heard we can try next day. We hoped "the weather of the third day will be good". Third day, we launched SPROUT-CAN before the debrief session, and we succeeded the communication of SSTV. However, the picture that SPROUT-CAN took in the sky was failed. After landing to the ground, SPROUT-CAN took pictures normally.
[Impressions]
From now on, we try to make camera that resists crash and to send SSTV more fast,in addition to decrease the noise of SSTV. We will realize amateur radio service of SSTV with SPROUT.
In the short term, we learned many things like the severity of the project and the gravity of the responsibility by making CanSat. And we had a very nice time that we meet the people that is gentle and friendly and we launched the CanSat that made by ourselves.
Thank you for the teacher and the senior who gave various advices, the people of UNISEC that gives the chance of the experiment and the people of Aero Pac that offers the rocket in addition.
