Receiving CASA certification in May, Sydney Airport’s GBAS system has been launched by deputy prime minister Warren Truss.

The new technology improves the accuracy of aircraft positioning and aircraft movements in low-visibility conditions.

It also enhances the airport’s safety systems, which include high-intensity approach lights and runway stop bars.

"We have invested $2.4bn in new facilities and this Australian-first is part of our ongoing commitment to delivering a world-class airport."

A single GBAS unit is capable of doing the work of six individual instrument landing system (ILS) units, which are located at the end of Sydney Airport’s six runways.

"We have invested $2.4bn in new facilities and this Australian-first is part of our ongoing commitment to delivering a world-class airport."
