[CanSat Introduction]
Our CANSAT CBC-03 was made last year. It has sensor systems like gyro sensors, acceleration sensors, and pressure sensors and flies back system in order to grasp an attitude of flying and wind. It also can come back and acquire much data of sensors. Our purpose was win at the come back competition and acquire data for our study "The Study on Flight Model of Small Unmanned Paraglider.
< 
[Approach and solution]
We prepared check of working, maintenance and examination of unfolding the paraglider carefully, because our CanSat has already been made last year, but it was very windy over our idea so we can't pursue, and we lost it. we had to spend the 2nd day and 3rd day to look for our CanSat , so we exhaust ourselves by walking all over the desert.
[Result]
IWe were disappointed, because we lost data of the flight and our CanSat. Our CanSat can't carry all installation because of restriction of the weight, and we thought easily that our CanSat doesn't go far away, so it didn't carry a transmitter. But it was blew off by the strong wind over 10 kilometers, so we can't pursue it. Fortunately people of AERO-PAC found it, so we can acquire tracks of GPS and data of many sensors. 
[Impressions]
After analyzing, we knew the things that the kill-switches were pulled after coming out and CBC-03 was moving to servos until landing. Its sensors could acquire data that is clear entirely and we keenly realized that our now systems and parafoil can't overcome strong wind at the same time. Seeking a method of raising the descent rate under strong wind is one of our subjects in the near future. We also want to make use of pressure sensors which are carried in order to grasp states of wind.
