Mission Overview• We will calculate the speed of sound as our
satellite rises to an altitude of 30km• We hypothesise that the speed of sound will
change in relation to the changes in temperature and pressure
• This data could be useful for scientists calculating the density of the atmosphere of another planet
Design OverviewBottom box
o Critical systems• Camera
• Micro controllers
• Heater
• Sensorso Microphoneo Temperatureo g-forceo Humidityo Pressure
Top boxo Speakerso Heater
Dry Ice Test
Dry Ice test- Temperature
Dry Ice test- Pressure and Humidity
Dry Ice test- Experiment
Consistent data, but worse with time
Calibration/Wind Test
• Microphone
• Filtering o Passive - thresholdo Active - stray data
• Precision of the clocko Percent error due to clock
Wind test
Drop Test• Heights• Drop angles
Kick/Whip Test
• minimal damage
Expected Results
• We expect to record accurate data from all sensors
• Hope to see predicted trends in this data
• From this flight, we hope to see how a change in altitude changes the speed of sound
Biggest Worries• The microphone won't pick up the sound
from the speakers• The carbon fiber tubes snap.• The camera lense fogs up.
Requirement Compliance
