1. GPS data such as date time, latitude,longitude, altitude etc.
2. temperature.
3. pressure.
All these data of CANSAT were obtained after
separation from Balloon by transmission.

Separation from Balloon

From this graph I think that it took long time to drop of altitude in
between 100 m to 80 m because of strong wind flowing at that momentHokkaido University

From this table we can see
total flight time after
separation was 1 minute 20sec. This flying time wasgreater than we expected.
Communication is lost after
it dropped on the ground.

1. Lack of experience. Since It was our firstexperiment with CANSAT around 100 -150 m
altitude.
2. Ignore the strong wind and not taking thecounter measures.
3. Insufficient area for that experiment.

Hokkaido University

New CANSAT was made after losing first CANSAT.
Mission for New CANSAT:
1. To take video
2. to measure temperature
3. to receive GPS data

Inadequate time for accomplishing all kinds oftest.
Such as
1. Vibration test
2. Shock test
3. Impact test and so on.

Hokkaido University Imagine every single thing that could happen.
 Ensure all tests before going to finalexperiment.
 Do not ignore any little confusion of totalexperiment.
 To consult many things with an experienced
person.

Hokkaido University

• To imagine all viable occurrences, possibility ofincidence in the time of experiment.
• To ensure all kinds of test, if it possible do afew drop tests from building before Paper
Rocket Test.
• To be prepared for substitute or back up plans.
Finally, “Think yourself as a leader of thisProject and make instantaneous decision totussle and intercept any kinds of obstacle.”

“We learn from our accomplished mission,
We also learn a lot from our abortive mission.”

I wish you all a successful, fruitful training whatever
the mission is abortive or accomplished.

Have a wonderful time in our beautiful campus of
Hokkaido University.
