C.N.S. Systems AB (CNS) provides solutions for communication, navigation and surveillance within maritime transportation and aviation. CNS solutions are based on high technical competence in transponder technology, radio communication and network solutions. Customers include civil aviation authorities, international airports and aviation operators. From the head office in Linköping, CNS markets their solutions globally.
CNS Systems delivers a new generation of air traffic control to the Swedish Civil Aviation Authority. JLT computers are used in airport ground vehicles. All vehicles on the runways at Arlanda airport will by the new system automatically send periodic reports with information about their identity, 3-dimensional position, velocity, intent and other pertinent data. Messages also include parameters required for the data link synchronization and slot allocation. In simpler words, every unit can broadcast all information about own position and intentions. At the same time they can listen to all other units doing the same and still remember every piece of information and in the same time be continuously chatting.
Based on a great Swedish invention
The new air traffic control system is based on Automatic Dependent Surveillance-Broadcast. ADS-B Networks supports surveillance, navigation, communication and real-time transfer of data in a way that all drivers not only know their own location, they also se other vehicles positions on a map in a computer display. ADS-B uses STDMA (Self-organizing Time Division Multiple Access), an ICAO standard for data communications via radio invented and patented by the Swedish genius Håkan Lans. In the timeframe of 2006-2008 ADS-B will be implemented by LFV as a nationwide network in Sweden, in some of the more remote locations of Alaska, in the Gulf of Mexico, Queensland Australia and also be used by the |

Cargo Airline Association as cargo carriers operating at their hub airports operate largely at night. In the long term, ADS-B will probably be used by all airplanes and all major airport ground vehicles.
Environmental and monetary savings
The Swedish Civil Aviation Authority is investing in a new countrywide ground network for more efficient air traffic guidance. Benefits will be savings for the airliners, less delays and less fuel consumption which will also be beneficial for the environment. A new principle for landing, “green approaches”, saves 250 litre fuel while landing an average airplane. More air traffic also creates crowding on runways and on the ground transport area. Computers and GPS transponders in the vehicles for the ADS-B application makes it possible to optimise the traffic whereby releasing space and improve airport security. A ground network for ADS-B is also significantly more cost efficient than traditional radar based surveillance systems. Using ADS-B is a true WIN-WIN concept for everybody except for manufacturers of radar equipment for airports. |
