KATHMANDU, Feb 04: The much anticipated En-route Monopulse Secondary Surveillance Radar (E-MSSR) at Bhattedanda and Terminal-Monopulse Secondary Surveillance Radar (T-MSSR) at Tribhuvan International Airport (TIA) have started operation from February 1st.

The radar was constructed in joint venture with Japanese International Corporation Agency (JICA) and Civil Aviation Authority of Nepal (CAAN).

Mr.Sanjeev Singh Kathayat, Deputy Director of CAAN said that the radar formally started operated from 6:30 am on Thursday.

The En-route Radar installed at Bhattedanda and Terminal Radar at the Tribhuvan International Airport (TIA) cover 75 per cent of total area of Nepal while making the Nepali airspace much more navigable. The radar can provide information about the height, range, angle or speed of aircraft through the radio waves. According to Mr. Sanjeev Gautam, Director General of CAAN, the installment and operation of the new radar will enhance air navigation throughout the country.

The new radar system will allow the distance between aircraft to be decreased to a great extent from 20-25 km to 5-9 km. It had previously been a difficult job to know the situation of flights due to poor radar surveillance.

The radar was flight-tested by America’s Federal Aviation Administration (FAA) on November 16 and 18 of 2017.

The previous 2012 radar used in TIA was also supplied by Japan’s Toshiba Company in 1998, and it was installed under the grant assistance from the Japanese government.

The new Mode S Monopulse Secondary Surveillance Radar (MSSR) can monitor the aircraft up to 250 nautical miles.  Its range reaches extending up to Dang in the west, and covers up the aerospace of entire eastern, northern and southern parts of the country whereas, the current existing 18 years old outdated radar’s range can only reach up to 60 nautical miles.
