Development of the User Interface for AIR-SPEC Eder Cervantes San Jose State University Mentors:Jenna Samra, Peter Cheimets, & Giora Guth
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
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
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
Configuration GPS Fiber-optic Gyroscope Operator Computer Fast-steering mirror Programmable Automation Controller Slit-jaw Camera
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
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
Summary AIR-SPEC will take data from 5 infrared spectral lines Stabilization to allow optimal data collection HMI GUI
