6. Goals for the Project Goal 1: – GPS Repeater System Goal 2: – Tracking Controller System

7. Purpose GPS Repeater System – Imposing physical structure – Will allow for indoor testing of HIBAL systems Source: Engadget. http://www.engadget.com/2007/02/21/underground-indoor-gps-repeater-maintains-your-position/

8. Purpose cont Tracking Controller System – Gathers GPS data from payload and chase vehicle – Calculates azimuth and elevation angles between two – Autonomously aims tracking devices at payload – Calculates projected flight path – Calculate estimated Landing Zones

9. Concerns and Solutions GPS Repeater System – Complying with FCC regulations – Complying with Building Codes Tracking Controller System – Complying with FCC/FAA regulations?? – Complying with Building Codes – Environmental issues
