  2. ASCEND Team • Robert Bearden • Dallas Hodge • Aaron Petreck • Ryan Sallee • Clayton Jacobs • Kevin Jordan • Mo Sabliny

  3. Outline • Payload • Structure • Components • Specifications of components • Software • Overall Payload Specifications • Conclusion

  4. Payload • Examine carbon dioxide emissions with respect to altitude • Was intended to be on HASP payload, but unable to due to shipping problems • Test structural integrity of Eaglesat structure for future balloon flights

  5. Structure • 3/4-inch thick hardened foam shell • Thermal insulation • Fiberglass epoxy cap • Built in-house • Cost effective • Experience working with fabrication

  6. Components • Arduino Mega Microcontroller • Seeeduino Shield compatible with Arduino • Carbon Dioxide gas board and sensor • Venus GPS antenna and receiver • LM19 Temperature sensor • Openlog (SD Card socket) • 11.1 V 2100 mah Li-Po battery • GoPro Hero 2 • Eaglesat Structure Rev 1.1

  7. Specifications • Arduino Mega • GPS • CO2 board • Temperature sensor • Openlog • GPS, temperature sensor and open log placed on shield • Require 3.3 V

  8. Specifications (cont.) • CO2 board • Operates at 5 V • Rated to operate to -40 Celsius • Board layout designed in house • GoPro Hero 2 • 720p, 30 fps • Extra battery backpack • Aimed horizontally

  9. Specifications (cont.) • Eaglesat structure • 1U (10cm x 10cm x 10cm) • Aluminum 6061

  10. Software • Programmed in Arduino • Sample rate: 1 per second • Temperature and CO2 readings will be unprocessed • Data Processing (post-flight) • Temperature and CO2 data points will be entered in a transfer function • Temperature will display degrees Celsius • CO2 data will read PPM (parts per million)
