Our CanSat & Mission
Our CanSat is consist of Two Satellites
『Tom』 shoots 『Jerry』 with camera
Mission
Tom Jerry
2009 9/18 Matunaga-Lab ARLISS Project 2009 3
Requirement & Design
• 『Tom』 must Know direction of itself
Hand made Sun Sensor used for this requirement
Get out-put of Sun direction
Direction of 『Tom』 determined
The Position of the Sun determined by time
Sun Sensor
2009 9/18 Matunaga-Lab ARLISS Project 2009 4
Requirement & Design
• 『Tom』 must know 『Jerry’s』 GPS data
『Jerry』 uplink the GPS position to 『Tom』
『Tom』『Jerry』
GPS data
Uplink !

2nd flight
2009 9/18 Matunaga-Lab ARLISS Project 2009 10
Result of 2nd flight
•22 Pictures(640×480picel)
•『Jerry』 uplinked data to 『Tom』(1time)
•『Tom』&『Jerry』 got their sensor data
•Rotation,Separation system worked
Success
failure
•『Jerry』 is not in these pictures
•『Tom』 froze 5min after launch
Example of pictures
2009 9/18 Matunaga-Lab ARLISS Project 2009 11
• Minimum success ○・separation system ・camera rotation system
・saving sensor data ・getting pictures
• Middle success △・communication Tom with Jerry succeeded 1 time
・Sun sensor worked
• Full success ×
・attitude determination failure
・taking a picture of launch site was failure
• Advanced success ×・Taking a picture of 『Jerry』 was failure
Success dgree(2nd flight)
