Abstract
The Unmanned Aerial Vehicles (UAV), or Unmanned Aerial Systems (UAS) are widely used today in real time, high precision reconnaissance missions. The UAS can lean on various types of the UAVs, whilst this paper deals only with multirotor UAV applications. The special flying abilities of the multirotor UAVs (e.g. vertical take-off and landing, hovering, flying at extremely low altitudes and airspeeds) open new areas in UAV applications. Challenges of the modern era put many problems to be solved such as problems of safeguarding in civil life, handling disaster management tasks, border control, and, finally, solution of force protection tasks in operational theatre, or out of war theatre. Author will lay down a brand-new concept of the UAV system applied in bad visibility to improve efficiency of the solution of the force protection tasks, which reduces human resources needed for this purpose. The proposed Night Watchbird UAV system is a new one using modern methods and principles to reach basic goal of reconnaissance providing real-time information for commanders, and for military forces, in general.
