The payload has been designed to follow the requirements defined by the Science Mission Directorate at NASA HQ for a sponsored scientific payload. It will record and transmit GPS position, pressure, temperature, relative humidity, ultraviolet radiation, and solar irradiance measurements during flight. The payload will also transmit IMU data to the base station for the detection of flight events. Primary Electronics- ArduPilot Mega with ATMega 2560
- ArduPilot Mega IMU Shield/OilPan Rev-H V1.0
- XBee Pro 900 Wireless Data Transmission System
- MediaTek MT3329 10Hz GPS
- 3x OmniVision OV9712 720p Cameras
Sensor Package - Honeywell HEL-705-T Platinum RTD Thermometer
- Will be calibrated using the on-campus Thermotron environmental test chamber.
- Freescale MPXZ6115A Absolute Pressure Sensor
- Will be calibrated using water columns and a vacuum chamber
- Thorlabs FGAP71 GaP Photodiode
- 150nm-550nm effective wavelength
- A 400nm shortpass filter will be installed to cut the effective wavelength to 150-400nm
- Thorlabs FDS100 Si Photodiode
- 350nm-1100nm effective wavelength
- A 400nm longpass filter will be installed to cut the effective wavelength to 400nm-1100nm
- Thorlabs FGA21 InGaAs Photodiode.
- 800nm-1800nm effective wavelength
- A 1100nm longpass filter will be installed to cut the effective wavelength to 1100nm-1800nm
- Factory provided calibration curves for each photodiode will be used for data analysis. The calibration curves will be verified using different light sources placed at various distances using the 1/r^2 relationship between luminosity and distance.
- Honeywell HIH-4030 Relative Humidity Sensor
- Will be calibrated using saturated salt baths.
