Do you know what INTAS is?

Integrated Tower Automation System - bought from the Canadians and worked tolerably well up to when I left the service. Sydney cannot be retro-fitted because it was designed and built as a peripheral tower. That is all the controllers stand next to the windows. Previous Towers were designed with a console set back from the windows, this allowed INTAS installations to be put in around them while the Tower continued to operate. I believe that thought was given to moving back to the old Sydney Tower to allow refurbishment or building a new Tower next to the current one. Neither has progressed because Airservices management's new toy is/are digital Towers. These are apparently cheaper to build because only the sensors, not the controllers, need to be at altitude. Australia's lack of high-speed digital transmission lines means, however, that the controllers still need to be very close to sensors. That could mean at ground level or a few hundred meters away. Given ASA's ability to finish any project, I would guess the can will continue to be kicked down the road until........
