According to the Federal Aviation Administration (FAA), an estimated 2.6 million commercial Unmanned Aircraft Systems (UAS) will be in service by 2020, which means the airspace is going to get crowded. NASA is leading a project to ensure those UAS, or drones, can safely share the airspace while still doing their jobs effectively. NASA enlisted the help of Botlink and other U.S. drone companies to test its drone traffic management system.
