Sunfish,
SBAS/WAAS ---- JUST FOR AVIATION ----- has failed benefit/cost twice now, what do you think had changed ---- to justify it??
Unlike years ago,
there is no pressing need for non-aviation use, but given what else is
IN PLACE,now, and mostly has been for years (note Airag's comment) and the advent of GPSIII. And it is GPS III, then in the future,
now a fact, that, along with other augmentation, has effectively eliminated WAAS for other than aviation use. That is fact, whether you accept it or not.
So, how it is SBAS/WAAS going to revolutionist Australian aviation???
Given the costs, and the relatively few airfields in Australia that have OR CAN HAVE an IAP (and decreasing) where, all of a sudden, is the big benefit. There isn't one, period.
I am certain you understand, the FAA had thousands of ILS IAP, where they could simply publish "overlay" approaches, no such thing in Australia.
The majority of runways in Australia are at airfields that are neither certified or registered, so no IAP of any kind ----- so much for helping the RFDS. The majority of certified/registered airfields only have non-precision approaches, so marginal at best minima reductions only. It is not needed for general aircraft navigation.
So, once again, I ask the question, what is the catch, what had changed to create this flurry of activity.
"Follow the money" ----- so where is the smart money on this one, because the "study" cannot tell us anything we do not already know ----- is it rights/patent holders for SBAS/WAAS trying to preserve a market against GPSIII??? In this case, at the Australian taxpayer's expense.
Nobody on this thread has yet come up with a supportable reason for what is going on.
Tootle pip!!
