8. What is UAS? And what is the difference between UAV and UAS? Unmanned Aerial Vehicle - A powered, aerial vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload. Ballistic or semiballistic vehicles, cruise missiles, and artillery projectiles are not considered unmanned aerial vehicles. –DOD Joint Publication 1-02 Unmanned Aerial System – A system comprised of one or more UAVs and the associated Ground Control Station for command, control, and communication and applicable payloads to perform various missions in either the civilian or military environment.

9. Mission Objective “The complete mission objectives are for an unmanned, radio controllable aircraft to be launched and transition or continue to autonomous flight, navigate a specified course, use onboard payload sensors to locate and assess a series of man-made objects in a search area prior to returning to the launch point for landing.” - AUVSI Student Competition Rules

14. Scored Factors Search Area Can choose the search pattern Flight altitude –Between 100 feet MSL and 750 feet MSL Dynamically re-task in flight –Utilize to locate a “pop-up” target Target Location Identification –Threshold: ddd.mm.ss.ssss within 250 ft –Objective: ddd.mm.ss.ssss within 50 ft

15. Scored Factors Landing Manual or autonomous landing –Objective: autonomous landing Control on landing –Scored Completion –“When the air vehicle motion ceases, engine is shut down, and the mission data sheet and imagery have been provided to the judges.” – AUVSI Competition Rules

16. Scored Factors Total Mission Time Allotted amount of time –40 minutes –Objective: 20 minutes Actionable Intelligence –Real time observation and target data recorded
