TECHNICAL SERVICES
Communications
M-NAV, PCL provides all types of communication ensuring safe air navigation services within the airspace of Republic of North Macedonia and at the two international airports, in accordance with ICAO SARPS and European Commission Directives which are binding for this area.
Air-Ground communication systems
Air-Ground communication systems are radio communication systems providing communication between aircrafts and air traffic control unit within the area of responsibility. Communication systems operate in the VHF band dedicated for this type of communication according to the international coordination for allocation of frequency of bands. Users of this service are aircrafts overflying the territory, aircrafts using the two international airports, sport aircrafts, general aviation as well as military aircrafts.
Ground-ground communication systems
Air Traffic Control Unit in Skopje exchanges various aeronautical data with the neighboring centers. Voice Communication Switch System (VCS System) is a system consisting of Controller Working Positions with touch screen pad, communication plugs (microphone, speaker headset) and peripheral communication systems (VHF radio, leased lines with the neighboring centers), enabling safe air-ground communication and ground-ground communication of air traffic controllers with the aircrafts and the neighboring centers, too.
VHF Direction Finder
VHF Direction Finders in approach have been installed at the two International airports.
Recording systems
Air Traffic Control unit in Skopje has in possession digital recorder of voice channels with a recording capacity of maximum of 120 channels. The records are kept on two independent systems within period of minimum of 30 days, in accordance with ICAO recommendations.
Air Traffic Control unit in Horrid has also digital recorder.
Navigation
Navigational aids (Navigational aids-Navaids) are radio navigation infrastructure which supports navigation for enroute, navigation for precision and non-precision approach, as well as navigation for precision landing.
Emitted radio waves provide the pilot information for aircraft position, direction and distance from the reference navigational aid located on the ground. As far as the latest aircraft generations are concerned, there is a possibility of simultaneous reception of more signals from the ground radio navigation aids and the aircraft position is determined with their processing.
Surveilance
Radar (an acronym of Radar Detection and Ranging) is a radio detection device used to determine the aircraft position and to provide a reliable surveillance image of the situation in the airspace and on the ground, ensuring a safe separation of controlled traffic and improving the ATC capacity in the controlled area. As far as civil and military air traffic control is concerned, M-NAV, PCL uses its own radar systems. These radar systems with the radar systems of the neighboring States are integrated in multiradar tracking systems in order to provide multiple coverage, high reliability and quality of target detection.
Data processing system
Information systems or data processing systems are integrated part of ATC system. Taking into consideration the fact that provision of safe and efficient air traffic is very complex process, the same one can not be imagined without sophisticated data processing systems. The data processed can be various, such as: radar data, pre-flight and flight plan data, meteorological data, technical-status data, air traffic flow data, statistics data etc.
Power supply
Power supply equipment/ systems provide a vital role in the operation of CNS/ATM systems and consequentially to safe and orderly operation of air navigation services. The electrical power supply sources/equipments/systems – quality, availability, capacity and reliability are one of the basic technical prerequisites for high integrity and reliability of CNS/ATM system services. To fulfill the requirementsthe proper design, installation, maintenance, monitoring and control should be met according to electrical power supply standards and regulations, both national and international. In terms of type and function, there is a clear difference between primary or commercial power supply (EVN) as an external element and the secondary power supply (backup, uninterruptible) as internal element of M-NAV. M-NAV buildings and systems for provision of air navigation services, are properly equipped with power supply plants and installations, starting from the connection points to EVN, through its own (internal) power sources and power distribution network, to the points of connection with consumers – CNS/ATM equipment/systems.
