State-owned air traffic management firm Airservices Australia has commenced essential upgrading works on the terminal area radar near Perth airport.
The project is part of an A$90 million ($93 million) Australian Mode S Terminal Area Radar (AMSTAR) programme.
The upgrade will ensure that the radar continues to provide safe and efficient movement of air traffic through airspace around the airport.
The Royal Australian Air Force radar at Eclipse Hill and Airservices' existing en route surveillance radar at Kalamunda will provide radar coverage for the Perth area during the upgrade.
An improved solid state primary radar with a 60nm (111km) range and a mode S (select) capable monopulse secondary surveillance radar with a range of up to 256nm will be installed.
"The new radar will deliver significant benefits to Airservices and the aviation industry, including higher rates of operational availability, improved data and less frequent maintenance requirements," says Mark Rodwell, Airservices executive general manager for projects and engineering.
Airservices has so far upgraded seven radars as part of the AMSTAR programme.
