The GNSS mandate

The Civil Aviation Safety Authority published Civil Aviation Order 20.18 in August 2012, with a revised version in December 2014, which mandates the use of Global Navigation Satellite System (GNSS) technology for all instrument flight rule (IFR) aircraft in Australian airspace.

On 4 February 2016, IFR aircraft will transition from ground-based to satellite-based navigation to using GPS as the primary enabling technology.
