OZ,
I could not find any date on that piece on the Japanese WAAS satellite, how old is it? Last I heard, negotiations to use that for aviation purposes over Australia fell over quite a while ago, and that system plays no part in the present so called "trial".

In isolation, everything in it is, of course, quite correct, but we are already doing all of those things, with "centimeter" or close to accuracy, now, that is the point I have been trying to make ---- it is not in the future, it is now. See one of my previous posts.

I can plot bore hole positions in surveying an ore body to 2-3 cm position right now, just like a survey I just had done of a hangar site for title purposes ---- on an aerodrome for which no acceptable survey was available.

EXCEPT FOR AIRCRAFT (in the absence of high speed trains) what new does SBAS/WAAS provide. That is why I said: Visit AgQuip at Gunnedah, see what's available right now. In the road transport business, for all navigation and fleet management purposes you don't even need SBAS, the average 3M accuracy of current non-aviation GPS is quite good enough. And 3M is quite good enough for parcel delivery.

For mine site management (not exploration) the preferred solution is company owned GBAS, because that gives the mining company complete control.

That is why I keep asking, what is the catch, what is different this time, given the services already available??

“Having a complete understanding of how the aviation industry sector can fully benefit from SBAS technology is crucial to the success of this trial,” Mr McCormack said.
The whole McCormack press release, also available of the Geoscience Australia web site, only blathers on about aviation, NO OTHER USE of SBAS/WAAS GPS was mentioned.

So, as we all know the press release is a load of old bollocks, what is really going on. What is the catch??

Tootle pip!!

PS: Whoever suggested it would save large overlaps plowing/sowing/harvesting --- are you serious, I could and did (and so could everybody else) run right along the furrow of the last pass before I was old enough to legally drive, and that was when all equipment was towed, not the great gadgets now ---- with GPS aided steering. I don't have to sit half sideways in the seat any longer, and the speaker phone, air conditioning and stereo is great ---- and I don't have to hop off the tractor and get underneath if there is thunderstorm and big hail.
Perhaps you could read up on soil science, and see how it is now possible to map a paddock, and meter fertilizer and trace elements to individual parts of a paddock for maximum even yield --- all done with current GPS positioning.
