♦ Kahului, Maui ♦ Mentors
– Riki Maeda and Daron Nishimoto
♦ US Government Support
– Defense – Homeland Security – Force Protection
♦ Projects
– CMOS Image Sensors – Adaptive Optics – Deployable Tracking Systems
♦ Why Track Satellites?
– Need to know satellite activity
– Quantity
♦ Tracking with Low Residual Error
– Keeping Satellites Centered in the Field of View (FOV) as they orbit
Deployable Tracking System Mobility Accuracy Resolution
Self Leveling North Finding GPS Enabled High Slew Speeds Precise Satellite Orbiting Data Large Mirror High Speed Camera
8” Aperture (203 mm) Focus F = 2000mm 8 x 50mm Viewfinder
Slew Rate 8° per second Autostar II Control System
Satellite Tracker processes Two Line Element Sets (TLES) to predict satellite
point towards and slew with the passing satellite. The predicted pass of COSMOS 1782
Color CMOS Chip with a 640 x 480 pixel resolution
♦ Weather ♦ Terminator
– The time period when satellites reflect sunlight, making them visible
♦ Satellite Magnitudes
– Visibility of the satellites
Used for Manual Tracking Controls telescope slew direction Controls telescope slew speeds
♦ Deployable Tracking System
– With better software, it will successfully track satellites – With a much larger aperture, it should successfully image satellites
Is Satellite Tracking Feasible?
Yes No
Improvements? Satellite Tracker telescope controlling software Time
