CAAN preparing for installation of ADS-B System at different airports of Nepal


Civil Aviation Authority of Nepal (CAAN) is preparing for the installation of Automatic Dependent Surveillance-Broadcast (ADS-B) system at various airports around the country to enhance the safe and effective flight operations.

CAAN, CNS Planning and Development Department has already announced invitation of sealed bids from the eligible bidders for the supply, delivery, installation and commissioning of ADS-B system at different airports of the country.

ADS-B is radically new technology that is redefining the paradigm of COMMUNICATIONS – NAVIGATION – SURVEILLANCE in Air Traffic Management today. Already proven and certified as a viable low cost replacement for conventional radar, ADS-B allows pilots and air traffic controllers to “see” and control aircraft with more precision, and over a far larger percentage of the earth’s surface, than has ever been possible before.

Recently, an interaction program among Airline pilots, CAAN Officials and MoCTCA (Ministry of Culture, Tourism and Civil Aviation) Officials was conducted in the presence of Hon. Minister Mr. Rabindra Adhikari, Secretary Mr. Krishna Prasad Devkota and Director General of Civil Aviation Mr. Sanjiv Gautam on aviation safety issues. The program was specially conducted in aim of reforming aviation sector of Nepal with enhancement especially in aviation safety and management. Installation of ADS-B and other airport equipment for safe flight operation had been discussed at the meet.

The newly installed En-route Monopulse Secondary Surveillance Radar (E-MSSR) at Bhattedanda and Terminal-Monopulse Secondary Surveillance Radar (T-MSSR) at Tribhuvan International Airport (TIA) has already came into operation from 1st February 2018.

The installed ‘En-route Radar’ at Bhattedanda and ‘Terminal Radar’ installed at the Tribhuvan International Airport (TIA) covers 75 per cent of total area of Nepal as well as makes Nepali aviation much more secure and systematic. The radar helps to provide information about the range, angle or velocity of aircraft through the radio waves.
