Apres Harfang (EADS Harfang)

| Sunday, April 1, 2012 | 0 comments

Apres Harfang (EADS Harfang) is a drone system used by the French Air Force, supplementing the RQ-5 Hunter. Unmanned Aerial Vehicles have become a must-have item for modern armies, and the pressures of modern campaigns are forcing rapid acquisitions. Mini-UAVs are being bought off the shelf, and leased tactical options like Boeing’s ScanEagles and Aeronautics DS’ Aerostars have carved out their own niche. These days, rent-a-UAS services even include high-end MALE (Medium Altitude Long Endurance) options like IAI’s Heron UAVs.

The most of the work is to add a satellite antenna at Heron remains a determined satellite oriented in any position of the aircraft. The satellite link is used to direct the aircraft and receive images unlimited distance or terrain, but with a delay of several seconds incompressible. Driving by radio beam, like the Heron, is still possible through the antenna perched on the back of the aircraft for operations close to the base or rolling. SIDM maintains the ability of Heron take off and land automatically. In addition, a defrost system, no need in Israel, is installed. The first devices were to be delivered to France in 2003, but the major difficulties encountered in developing the satellite antenna push the first flight in 2006.

The control station is composed of four modules, numbered M1 through M4:
  • M1 is the mission preparation station. It is based on a Mirage 2000 briefing station.
  • M2 is the command and control unit, used mostly during take-off and landing. Most of the mission is automated.
  • M3 is the data collection unit, receiving information through satellite communication
  • M4 is the military intelligence centre.
A line-of-sight link allows for direct communication up to 150 to 200 kilometres away. Longer ranges utilise a directional antenna and geostationary satellites. The Very High Frequency and Ultra high frequency communication relay provides for links to ground units and air traffic control.
