Data transmission space system for air traffic control in Russia

The Federal Program of Modernisation of Universal Air Traffic Control System of Russia provides use of space facilities for navigation, tracking and communications. To fulfil this provision of the program, the data transmission space system for air traffic control has been developed. This system is designed to provide automatic air traffic control system operation in Russia. It performs the following tasks: global navigation support of planes under accuracy of coordinates definition better than 100 meters; precise navigation support in airport areas; communications services between regional air traffic control centers and aeroplanes (mobile telecommunications); automatic dependent tracking of aeroplane flights; and voice and data communications between components of the air traffic control system. The Federal Program is based on the deployment of satellite systems.
