UAV SUKHOI

SUMBER : SUKHOI

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.

UNMANNED AIRCRAFT ZOND-1

The unmanned aircraft Zond-1 is designed to perform the following tasks of national economic importance:
• ATC support
• Relay of communications and television transmissions

UNMANNED AIRCRAFT ZOND-2
The unmanned aircraft Zond-2 is designed to perform the following tasks of national economic importance:

• Monitoring of the Earth’s surface:
  - radar-based (sideways-looking radar with synthetic aperture) monitoring to identify emergency conditions (river floods, ice floes, aircraft search-and-rescue missions, etc.), as well as to record topographic changes; - electro-optical monitoring, including IR and TV and low-level video links, to identify fires, developments in emergency situations, and to support search-and-rescue operations.
• Monitoring of the ozone layer

UNMANNED AIRCRAFT ZOND-3
The unmanned aircraft Zond-3 is designed to perform the following tasks of national economic importance:

• Monitoring of the air environment and ground/water surface:
  - radar monitoring (sideways-looking radar with synthetic aperture) to surveil emergency conditions, record topographic changes, perform ice coverage reconnaissance, and to assess the status of oil and gas pipelines; - electro-optical monitoring, including IR and TV and low-level video links, to monitor emergency situations and follow their development, and to support search-and-rescue operations.
• Air pollution monitoring
• Relay of communications transmissions
