Australia's Civil Aviation Safety Authority (CASA) will shortly launch a 12-month test of new-generation GPS satellite navigation system avionics.

CASA is using UPS Aviation Technologies' (UPS AT) Apollo CNX-80 integrated avionics system that was recently certificated by the US Federal Aviation Administration. UPS AT is being acquired by Garmin International. The Apollo system features a wide area augmentation system (WAAS) GPS navigator, built-in VHF navigation/communications, high-resolution colour display and the ability to control a remote transponder. It is the first integrated navigator to receive authorisation under the FAA's latest WAAS/GPS requirements - TSO-C146.

CASA rules require an alternate approach based on a terrestrial navigation aid, as earlier GPS receivers were only capable of detecting a GPS satellite fault and not taking it into consideration.
