Overview of ESAM Balloon Satellite Mission for Electromagnetic Spectrum Data Collection

This presentation outlines the mission of the ESAM team, which aims to send a balloon satellite to an altitude of 30 kilometers to collect wattage data of the electromagnetic spectrum. Utilizing infrared and ultraviolet sensors, the project investigates light flux in the troposphere and lower stratosphere. Results indicate an increase in ultraviolet intensity with altitude. The team reflects on challenges faced, such as sensor malfunctions, time management issues, and the need for improved data parsing. Lessons learned emphasize teamwork, preparation, and the importance of understanding hardware intricacies for future missions.

  2. Mission Overview • ESAM’s mission is to send a balloon satellite to an altitude of 30 kilometers in order to collect wattage data of the electromagnetic spectrum. • An infrared sensor and an ultraviolet sensor will be used in order to determine the flux of infrared and ultraviolet light throughout the troposphere and lower stratosphere. • The sensors will collect data in the ranges of 210-380nm in the ultraviolet and 750-1400 in the infrared. • We expect to see an increase in both infrared and Ultraviolet intensity as a function of altitude.

  4. Design Overview Hardware • 3 UV sensors • 1 IR sensor • AVR and misc. • Camera • Structure

  6. Infrared Sensor

  7. All Sensors

  8. Everything!

  9. Structure

  10. Results and Analysis • Predicted: Ultraviolet and infrared light intensity will increase as altitude increases • Actual: • Ultraviolet intensity increases as altitude increases • Infrared light intensity did not continuously increase

  15. UV Sensor 2

  16. UV Sensor 3

  17. IR Sensor

  18. Failure Analysis • AVR camera activation failed • When plugged in, the camera immediately turned on. • Several attempts to unplug and re-plug. • Camera now fixed, polarity of wires reversed. • Not actually a big deal, didn’t effect pictures… • ready for re-fly!

  19. Conclusions • UV light increases with altitude • Ground flux: ~0 W/m^2 • Max flux: ~1.4 W/m^2 • IR light more complicated • Possible sensor malfunction.

  21. Lessons Learned What we would have done differently. • Time management (baseline testing, opp amp) • Better understanding of opp amp hardware • Better understanding of parsing data. • Use two more IR sensors for more accurate data If we could change it… • Better time management • Debugging AVR sooner, rather than later

  22. Re-fly • Storage: taped shut but not sealed to store it until the next flight. • Activated for next flight: Payload should: • be carefully sliced open • have the batteries replaced • be armed • be sealed shut before it will be fully ready to fly again.

  24. Message to Next Semester Some people seemed to dislike this class but we really liked it. We had a good group that worked well together and has diverse talents/knowledge coming into the project. We were fortunate enough to have people with backgrounds in computing, astronomy, business, and leadership. Be prepared to work a lot but…it’s really not that bad, just manage your time well. Expect to work more than once a week; we met three times a week and still ran out of time. Even if you think you’re ahead of schedule, don’t take a week off, keep working. Also learn as much about your hardware as much as you can so that when “the sh*t hits the fan” you know how to fix it. Team leader, don’t be afraid to tell your team what to do. Assign them different sections of the DD and make sure they get done when you want them done. Overall this class was a valuable learning experience in more ways than just launching a satellite. And it was fun!
