  1. X-IPITER 2005 AUVSI Undergraduate Student UAV Competition Mississippi State University November 19, 2004

  2. Team Members • Advisors • Dr. Randolph Follett (ECE) • Calvin Walker (ASE)

  3. Objective “Design and build an unmanned aerial vehicle (UAV) capable of performing realistic autonomous missions in an aviation environment”

  4. Mission Profile • Autonomous or manual takeoff • Autonomously navigate through specified waypoints (if manual takeoff, demonstrate transition to autonomous flight) • Dynamic re-tasking of aircraft during flight • Provide imagery, total number of targets, GPS coordinates, and target orientation • Autonomous or manual landing within a specified area

  5. Competition Restrictions • Ceiling: 500ft AGL • Floor: 50ft AGL • No-fly zones: TBA • Max Weight: 55lbs • Max Mission Time: 40min
