Mentors:Jenna Samra, Peter Cheimets, & Giora Guth

2. Why does AIR-SPEC exist?
In summer of 2017 there will be a solar eclipse
Opportunity to study spectral lines
Five spectral wavelengths of potential interest to measure magnetic field
B-field has far-reaching implications
Solar weather
CMEs
Coronal Jets
Judge 1998

3. What is AIR-SPEC?
Airborne Infrared Spectrometer to collect data during eclipse
Loaded onto Gulfstream V jet
Altitude: 14.9 km
Clears most of the atmosphere
Minimal infrared absorption from water molecules
Includes image stabilization system
Track sun
Compensate for plane motion

4. Image Stabilization System Components
Function
Programmable Automation Controller (PAC)
Control of instruments, connection to computer
GPS
Determines position of plane
Fiber-Optic Gyroscope
Measures yaw, pitch, & roll
Voltage driven mirror
Follows sun
Slit-jaw Camera
Captures visible light
Computer
Human use, sends commands
Laboratory test setup

5. Configuration GPS Fiber-optic Gyroscope Operator Computer
Fast-steering mirror
Programmable Automation Controller
Slit-jaw Camera

6. Human Machine Interface (HMI)
Creates connection between Client(User’s Computer) and Server(PAC)
Allows data transfer between the two
Shared memory
Data transfer
Values:
Gyroscope rates
Mirror angles
GPS location and time
Calculated solar ephemeris
Mirror az/el

7. Graphical User Interface (GUI)
User Friendly control of instrumentation
Functionality:
Turning Stabilization on and off
Idle Mode
Monitor Mode
Track Mode
Manually input mirror az/el
Calculating solar ephemeris
Storing data collected onto computer
Future: Attitude adjustment

8. Summary AIR-SPEC will take data from 5 infrared spectral lines
Stabilization to allow optimal data collection
HMI
GUI
