Will New ADSB IFR Requirement Reduce Safety Even More?
"Far more"? What are they?
It will provide precision approaches to every airport in Australia if they build enough ground stations. Basically the ground station acts as a satellite. As the poster suggested that's better then ADSB on the whole.

Bloggs, if you're right, then the rest of the world is wrong. SBAS provides LPV approaches to any runway, a 3D position solution that gives you vertical guidance to the threshold every time. Safety benefits of that are massive. ADSB in Class G on the other hand, only provides an advisory service because there is no ATC control and separation standards applied
Safety benefits of that are massive.
We don't have Class G here, despite what Dick Smith foisted upon the editors of AIP.

I get it, FB, and I'm not disagreeing with the technology available nowadays to a terrorist with $$s in his pocket. What I am at odds with is the tenuous relevance to ADSB. You've managed to squeeze in your point because the drones use GPS, as does ADSB but, whereas it's obviously a favourite topic of yours, it really has nothing to add to Dick's question. Might I suggest you start a different thread and discuss your GPS drones there, rather than clog up the ADSB thread with irrelevance.
(And the gyros know where they are in the first place because you tell them, just like every inertial platform and you don't need GPS for that).

Oh, and here's me thinkin it do...

...rather than spend the money in fitting the ADSB, they are going to simply take their aircraft out of the IFR category and only fly VFR...
...scud running all the time because of not being able to afford the cost of ADSB...

"(And the gyros know where they are in the first place because you tell them, just like every inertial platform and you don't need GPS for that)"
Pontius, there must be something i miss-understand about the 'gyros' you use. Lets run a scenario: An islamic nutter is out in the wilds of a little island just north of Oz and sets up his little bomb drone for a target in Darwin. Half kg ordinance payload and requires targeting accuracy of one cubic metre of airspace and within a few minutes of a set time.
Pontius, if the terrorist does not have the availability of GPS, will your 'gyros' be able to hit the target as per scenario?
And "the technology available nowadays to a terrorist with $$s in his pocket..."
Pontius, i suggest you actually research the subject. The 'cost' is peanuts. Like everything in life, terrorism gets cheaper by the day. And there is no 'peak' terrorism in sight..

Bloggs, we are off topic now, all I will say is :
1. The rest of the world have implemented SBAS first.
2. There are over 7000 APV approaches published, available to those with suitably equipped aircraft (TSO C145 or 146)
3. These are flown using both the latral and vertical guidance information.
If you don't think this clearly demonstrates the rest of the world has realised the safety benefits of SBAS, well....

I saw a recent ADSB transponder install in a Piper Commanche (Bendix King) and it cost $5k.
Exact details are hard to decipher but it is generally accepted that a TSO C145/146 WAAS GPS will be required to provide a suitable GPS data source for ADSB.
So it depends on what you have fitted already, an Garmin 430/530 can be upgraded to W spec, other stuff your are looking at new units.
