Australia plans en route radars replacement

Airservices will begin a major project to replace ageing en route radars across Australia with the help of Indra
Airservices will begin a major project to replace ageing en route radars across Australia following the signing of a contract with Indra Australia.
The $45 million contract will see the nation’s air navigation service provider replace 11 en route radars that provide an essential back-up to satellite surveillance systems such as Automatic Dependent Surveillance-Broadcast (ADS-B).
Airservices General Manager Technology and Asset Services, Alastair Hodgson, said that the radars were used by air traffic controllers to provide core en route separation of aircraft operating in high level airspace.
“The replacement of these radars is essential to maintain and enhance the level of service and safety assurance we are able to provide to the aviation industry and the travelling public,” Mr Hodgson said.
“The new equipment will offer increased reliability and, through the inclusion of Mode S (select) capability, will deliver greater accuracy.”
The radars, when located in close proximity to major airports, also augment the surveillance coverage offered by nearby terminal area radars.
Sites will be scheduled on the basis of operational priority, the condition of the existing radar facility, and to minimise any disruptions to the travelling public. The first radar to be replaced is expected to be The Round Mountain in northern NSW.
“This radar has been determined to be our priority as it provides critical surveillance coverage over a busy flight corridor between Sydney and Brisbane,” Mr Hodgson said.
Other radars to be replaced include Hann Tableland (QLD), Mt Bobbara (NSW), Mt Kalamunda (WA), Mt Boyce (NSW), Tabletop Mountain (QLD), Hardgrave (QLD), Mt Alma (QLD), Summertown (SA), Mt Macedon (VIC), and Swampy Ridge (QLD).
The existing en route radars were installed early in the 1990s with a planned life of 15 years. They have been refurbished to extend their life until the end of 2015, by which time the planned replacement of the 11 radars will be complete.
The project includes logistical support services to maintain the new radars through to 2030 and transportable radar systems to provide interim surveillance services while work is underway.
