Henriksen, NASA/ITT UAS Study Task Final Report, NASA Contractor Report CR-2008-214841, February 2008. There are significant activities taking place to establish the procedures and requirements for safe and routine operation of unmanned aircraft systems (UAS) in the National Airspace System (NAS). Among the barriers to overcome in achieving this goal is the lack of sufficient frequency spectrum necessary for the UAS control and air traffic control (ATC) communications links.
