Welcome to the DragonFly UAV web site!  Funded by the FAA, Stanford University researchers are developing systems to permit the robust navigation and enhanced automatic control of Unmanned Air Vehicles (UAV's).  At the forefront of this effort is the DragonFly Project.  In simple terms, the primary objective of the DragonFly Project is to equip a large (12-foot wing span) radio-controlled model airplane with avionics such that the plane's autopilot will be able to autonomously direct the plane through a series of demanding aerobic maneuvers such as barrel rolls and loops.  To accomplish this objective, the DragonFly team will combine GPS positioning data with output from an inertial measurement unit.
