The German air navigation service provider,
DFS, and Deutsche Telekom have jointly developed a system to enable the safe and
fair integration of unmanned aircraft systems into lower airspace.
The technology is currently being tested in a
diverse range of practical trials.
An unmanned aircraft system traffic management
(UTM) system locates drones using the mobile telecommunications network and
incorporates them into an air situation display. The technology has been
developed especially for drones flown beyond their operators' visual line of
sight - for example, for control flights along pipelines, or for drones used in
agriculture or in search and rescue missions.
Mobile data creating an air situation display
Unmanned aircraft systems transmit their
position data to the UTM system over the mobile network. For this, they are
equipped with an LTE modem, a GPS module and a mobile transmitter. The UTM
system creates an air situation display from these position data. The display
shows any surrounding traffic and warns of conflicts. Prohibited areas, around
airports for example, can also be included in the system.
The system can detect unmanned aircraft
systems up to a height of 100 metres. An advantage of using telecommunication is
that the mobile network provides complete geographical coverage.
The UTM system is based on the DFS
multi-sensor tracker Phoenix, which was developed by DFS and is in use to
display radar data for air traffic control. DFS adapted the tracker to correctly
display the movement patterns of drones, which are significantly different to
those of conventional aircraft.
Infrastructure for the lowest airspace
The system can be linked to existing air
traffic control systems and warn air traffic controllers of conflicts. The
system's capabilities go beyond simply locating unmanned aircraft systems,
however. Chart material, prohibited areas and meteorological information are
also integrated.
Data from detection systems can be added too,
meaning the system could be used as the basis for counteracting intrusive
drones. DFS and Deutsche Telekom set up the research project in 2016 and have
been working on a solution for the safe and fair integration of drones in
airspace since then.
DFS will be showcasing its UTM solution at
the World ATM Congress in Madrid (6 to 8 March 2018). Booth no. 834.
