This category can further be divided into six subgroups namely; short-range, medium range, long-range, close range, endurance, Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicles (UAVs). The long-range UAVs are technologically more advanced as they use satellites in order to overcome the communication problem between the UAVs and the ground stations. This communication problem is generally caused by the curvature of the earth. The medium, short and close range UAVs can operate in limited space majorly because of the lack of satellite communication systems. The Medium Altitude Long Endurance (MALE) can be used for forty hours at a distance greater than three thousand kilo metres. They can also be used to fire precision guided missiles. An example of the Medium Altitude Long Endurance (MALE) is 'Predator'. (Cavoukian 2012, 6)
