Ugglan - Sagem Sperwer (1999- )
Test with UAV systems have been
made in Sweden since the end of the sixties. After trials K 3 at
Karlsborg, the Army decided to order three of the French Sperwer UAV
systems, manufactured by Sagem. The Swedish name is ”Ugglan”
- ”the Owl”. The aim is to integrate the system in the Army
intelligence battalions in
2004 and have the system ready for international peace-keeping mission
some years later. The development of the system is still located at K 3
at the fortress of Karlsborg close to lake Vättern. The Army took
delivery of the three units between June 1999 and April 2000.
The delta-winged Ugglan has a
relatively long range (75 km - 3 hours) and capability to operate both
in daylight and in darkness. An Ugglan unit consists of three UAVs, a
ground station with a radio link, a launching vehicle with catapult, a
salvaging vehicle, a preparation vehicle, etc.
The UAV flies according to a
programmed route, but can if necessary be controlled directly by the
pilot. The picture/film is linked in real-time from the UAV to the
operator’s display. The Ugglan is equipped with GPS and inertial
The sensor pod of the UAV
contains one IR-camera and one b/w high-sensitive (NIV) TV-camera. In
the front of the UAV, a colour TV camera (CCD) is fitted for navigation.
The Ugglan is launched by a
pneumatically operated catapult. After completed mission, the landing is
made by means of a parachute and air cushions.
The Ugglan is powered by a 65 hp
Rotax 582 engine.
