After the official handing over of the first series-system of
the Rheinmetall reconnaissance drone 'KZO' ("Kleinfluggerät Zielortung") to
the German Army, EADS Defence Electronics has now started the series
production of the 'KZO' data-link system. The data-link system guarantees a
world-wide unrivalled jamming resistance in the data-transfer between the
drone and the ground station.

"Our data-link contains world-wide unrivalled capabilities which can be used
on the most differing aerial devices. This is the most modern technology for
the future topic unmanned air vehicles" stated Bernhard Gerwert, CEO of EADS
The data link system consists of an Air Data Terminal (ADT) in the drone and a
Ground Data Terminal (GDT) on the ground. In doing this, the extremely small
and compact ADT was specified using special miniaturisation techniques
especially for unmanned aerial vehicles. It permits interference-free
real-time data-transfer of large quantities of data over more than 120 km.

Using the data-link system, mission information and control signals are sent
from the ground to the drone, as well as vice versa, the operational data of
the drone and video signals via broadband channels are transmitted back to the
ground station. In case of lower demands on the jamming security, the
transmission rate can be increased.
Due to the automatic alignment of very narrow beam antennas in the drone and
on the ground, the application of spread spectrum and frequency-hopping
technologies as well as further state of the art methods in signal processing,
the data-transfer displays a previously unachieved resistance against jamming.
In addition, Defence Electronics uses radar-techniques which measure the
position of the drone with the highest precision independently of GPS.
Therefore, missions can be safely carried out despite GPS failures. The first
development steps for the data link were made by the EADS predecessor
companies on the German and French sides in the Brevel programme.
The EADS data link is also being used in a modified form in the
experimental program SIDM (Système Intermédiaire de Drone MALE), which is a
reconnaissance UAV system for altitudes up to 12,000 metres and extended
flight times. The data link system has also demonstrated its reliability in
the Rheinmetall Defence Electronics'
