Flight #1: Nov. 22, 2008 Launched from
Gila Bend Traveled 61.1
statute miles Flight time:
2:02:32 Peak Altitude:
95,867 ft. Landed south of
Chandler Source: kd7lmo.net

Flight #1 (continued) HOBO datalogger
recorded temperature and relative humidity
IMU data was retrieved but could not be analyzed
GPS tracking was successful up to burst and then during part of the descent Source: kd7lmo.net

Flight #2: April 4, 2009 Launched from Gila
Bend Traveled 81.4
statute miles Flight time: 1:57:05 Peak Altitude:
89,676 ft. Landed East of
Florence

Flight #2 (continued) Temperature, pressure, and solar cell
data successfully recorded GPS never acquired satellites due to
antenna installation

Conclusions Two successful launches
Recovered payload after both launches Gathered temperature, pressure, and IMU data Cannot put aluminum tape over GPS antenna
Created own systems instead of using heavy, off the shelf systems
Improved structural layout to improve wiring layout
