Communication Engineering Section – RMA

The Area Controlled Center at Ratmalana was upgraded in mid 2000 with a fully integrated Air traffic Management system, “EUROCAT 1000” which inclusive of oceanic and radar Control facilities. This system comprises of satellite based Automatic Dependant Surveillance and Controller Pilot Data link Communications facilities


Maintain all navigational aids up to the international standards laid down by International Civil aviation organization. Namely, ILS, DME and DVOR. Primary & Secondary Radar equipment, relevant data processing and display systems are also provided to the air traffic control department. Laser guided aircraft docking system, Automatic weather observation system and trunk communication system, are also maintained by this section.


The functions of the Electronics & Air Navigational Engineering section at MRIA is to maintain all navigational aids up to the international standards laid down by ICAO. ILS, DME, DVOR, Radar feed display, relevant data processing and display systems are also provided to the air traffic control department. AWOS, trunk communication system and airport security baggage clearance & security screening systems are also maintained by this section.


Which is located at the Summit of mountain Pidurutalagala, 8295 ft above sea level. Both Primary & Secondary surveillance Radar were located at the station giving coverage of 200 Nautical Miles. In addition, this station is serving as the repeating station for extended range VHF communication, covering more than 350 Nautical mile radius. The Radar information & VHF Communications are linked to Colombo area control center via a digital Micro Wave Link.


Its main function is Transmitting of aero mobile messages (from aero mobile center, Ratmalana) on H.F. SSB/AM to long distance aircraft. For this purpose, the station is equipped with several high power HF Transmitters and large Antenna field for the HF Antenna Structures.


The main function of the station is to receive the Air to ground aero mobile communication and to relay them to the aero mobile Communication center at Ratmalana. To achieve this task the station is equipped with a large Antenna field approximately 65 Acres along with highly reliable Receivers and multi channel radio Link to Ratmalana.
