2. Expected Results
Should be able to see magnetometer reacting to orientation
Determine how much vibration the payload was under and ensure that pressure, altitude and acceleration characterize test environment
See GPS drop out (ITAR altitude limit)
Collect 2-hours minimum of data
Gain better understanding of satellite orientation with earth sensors

3. The Unexpected During launch preparations, it was noted
that there was no power to flight computer
and sensor board due to bad DC/DC converter
After working all night the problem was
remedied by replacing the DC/DC converter
with voltage regulator loaned to us by Washington
University – St. Louis and the help of Missouri Rolla, but
unfortunately we lost some of our sensors.

5. Box Retrieval GPS antenna tore off. Earth sensors loose, but intact.
Structure otherwise sound.
Contents appeared intact.

6. Actual Results Time Scaled correctly indicating 10 second sampling
Magnetometer reported serial number and began returning data
GPS bearer of bad news

8. Conclusions & Actions Conclusions Actions
Upon repackaging at 4:30 AM Power cable broke
Unnoticed until retrieval
Dead Payload before Activation at Launch Site
Actions
Further analysis of data to collaborate GPS time with System time
Going to add LED off of Power LED spot of PC/104 computer
