Airservices Australia has upgraded its very-high-frequency (VHF) radio network in order to enhance communications between aircraft and air traffic controllers in Australia.
The project involved the replacement of old analogue and relay-based VHF radios with new digital equipment at 39 air traffic control communication sites in Australia, including 26 aerodrome control towers.
The upgraded radio equipment will have enhanced capability to monitor faults and allow remote fault rectification by technical staff.
It will also include digital links between equipment, increased reliability and maintainability, and constant monitoring of equipment.
The project also included the installation of new antennas, lightning protection and earthing associated with the VHF radios.
Airservices has replaced the VHF system as part of its five-year, AUD900m ($806m) capital expenditure programme to modernise and enhance aviation infrastructure, systems and equipment in Australia.
