General Atomics Aeronautical Systems, Inc. (GA ASI) and the Company's "Team Sky Warrior" partners AAI Corporation and L-3 Communication Systems-West have successfully first-attempted automatic takeoffs and landings of a Sky Warrior UAS controlled from the AAI-developed Extended Range/Multi-Purpose (ER/MP) One System Ground Control Station (OSGCS). Three automatic landings were successfully executed at GA-ASI's El Mirage Flight Operations Center in Adelanto, California, on August 29th, followed by three successful automatic takeoffs on September 26th. GA-ASI's Sky Warrior aircraft was under full line-of-sight command and control through the L-3 Communication Systems-West Tactical Common Data Link (TCDL). Automatic takeoff and landing using TCDL represents a significant technical advancement in ER/MP UAS Program development and an important step in the maturation of diverse technologies prior to fielding the system, which is expected in July 2009.
