LATAS provides flight planning, tracking and sense & avoidance to each drone that flies within the National Airspace System. LATAS - Low Altitude Tracking and Avoidance System. These flights pose a major safety hazard to pilots of manned aircraft. Due to the small size and low altitudes in which these drones fly, Federal Aviation Administration Air Traffic Controllers are unable to safely integrate drones into the airspace. This is due largely in part that current radar technologies and ADS-b reporting systems are unable to locate and track the drones.
