So doing some firther reading Australia might implement sbas as an interim to dual channel gps which isn't scheduled until 2020.
In other words we will need to wait until 2020.
Are there any gps precision approaches in Australia yet? Looking at the latest DAPs there are rnp approaches into some of the major airports but not sure how it's done? GBAS or SBAS? I know we don't have WaaS as it requires 25 ground stations to work in Australia.
They are labeled as rnp approaches which as I understand is just the new name for the RNAV (GNSS) approaches.
Can't seem to see on the plate if it has a vertical guidance or not.
