A UAV (unmanned aerial vehicles) can be deployed for many roles. Unmanned aerial vehicles (UAV) can be used to perform many tasks unsuitable for manned aircraft, due to a number of reasons. Such tasks include: monitoring of air space, ground and water surface, environmental monitoring, air traffic control, maritime traffic control, and support of communications systems.

The monitoring of air space, ground and water surfaces may involve, depending on the nature of the tasks addressed, aerial photography, monitoring of water and weather conditions, atmospheric sounding, radiation monitoring of disaster areas, seismic monitoring, verification of compliance with treaty commitments, prospecting, soil sounding, and surveying of ice coverage and sea conditions.

Interest in UAVs is due to their economical operation, the elimination of danger to human crew, the absence of g-load restrictions imposed by human physiology, and the availability of an option to arrange monitoring from a variety of locations within a short period of time.

A feature of a UAV is an option of monitoring ground and air space at a great distance from the target using a variety of sensors.

A UAV can be deployed not only for the tasks above, but also, for example, for surveillance of national borders.

All the above stakes out a broad range of tasks which can be very efficiently and economically addressed by deploying UAVs.
