1. A simple CANSAT KIT Jens Dalsgaard Nielsen
Section of Automation & Control
Student Sat Lab
Aalborg University – Denmark

2. The overall Goal Why building student satellites and cansats ?
The students
We think space is interesting
We would like to do space stuff
We would like to become space engineers
Educational site/the teachers
We think space is interesting :-)
We will educate “the best engineers in the world” ;-)
We will attract even more students to our university
...

6. so - Let's get it done

7. The method – CANSAT kit - a pre cooked solution
We will
measure on nature
collect information
process information
and ...
carry all this out in context of math, physics, biology etc

8. at a modest price arduino ~ €20 shield ~ 0 radio ~ €30-45
sensors (3 axis accelerometer, pressure, temperature) €35
in total less than €100 or so

9. Where will we end ? 1 2 4 3 5 6

13. Temperature Simple sensor Easy to handle Slow due to mass
calibrated ab fabrique

16. PRESSURE

17. Accelerometer
MMA7361L
3 axis MEMS tech
+/- 1.5/g G

20. Arduino as measuring device
All analog inputs measure 0-5V
simple simple simple ...
Measurements are represented as an integer :
0V ~ 0
5V ~ 1023
2.5V ~ 512
etc – just a matter of scaling – by you ! (primitive instrument)

21. Arduino measuring Voltage - WARNING
Input voltage must be in range [0-5] V
If you go above you kill it – or at least destroy input port
If you go below ''
SO BEWARE
ELECTRONICS IS DRIVEN BY SMOKE ...
PROOF ?

PROOF ?
when smoke get's out it stops working ...

23. step by step for every sensor/interface
soldering and mounting
Sensor sensitivity and calibration
temperature 20C ~ 20*10mV = 200 mV
~ (200/5000)*1023 = 40-41
Accelerometer
see data sheet (is NOT calibrated when manufactored)
Pressure/height
see data sheet – (is calibrated when manufactored)

26. Missing ? Hands on assembly and test of kit Experiment planning
what to measure
sample rates
telemetry
robustness issues – (data preservation)
Planning of experiment
what, who,
Programming skills
just do it

27. One more thing...

28. It's not all about space It you can do space you can do anything :-)
Environment
sensors for CO2, NOX,...
Health
testing running style (acceleration on knees,...)
alarm systems
just fantasy sets the limit (I know its big words)

29. Two minuttes TV kitchen (but nothing is pre cooked!)
