The new Route Surveillance Radar (RSR) at Mount Parker, Quarry Bay, was opened in 2004 to enhance the surveillance capability of the Hong Kong air traffic control system and help maximise airspace capacity and ensure flight safety.
The radar antenna is 9.7 metres high and 13.7 metres wide, and the radome has a diameter of 15 metres. It is encased within a radome and can work continuously under all weather conditions even during typhoon.
