Airservices Australia has commissioned an upgraded Australian dollars (A$) six million ($6.4 million) terminal area radar at Sydney Airport.
The upgrade is part of Airservices' national A$80 million Mode S Terminal Area Radar (AMSTAR) project and will increase the facility of air traffic controllers to monitor aircraft in different weather conditions.
"Mode S technology delivers significant benefits to Airservices and the aviation industry, including higher rates of operational availability, the quality and quantity of the data received, and less frequent maintenance requirements," said Airservices general manager technology and asset services Alastair Hodgson.
The new equipment has an improved solid state primary radar with a 60nm range. It also includes a Mode S capable monopulse secondary surveillance radar with a range of up to 256nm.
The upgrade follows similar upgrades at Gold Coast, Melbourne and Darwin airports.
