27/09 and Leadsled,
Where do you guys come up with this cr&p? You both have over active imaginations....
27/09 this may be hard to believe but SBAS technology has moved on, it has been around for quite sometime. The SBAS service being offered to Australia is the most up to date version of the technology. The problem is that aviation avionics are still using the SBAS legacy technology. Its the new technology that GeoscienceAus and other industry sectors want, the aviation sector are trying mount a strong case to ensure that what ever SBAS is chosen, that it will support legacy aviation avionics....but yeah its a conspiracy. Make no mistake that if your aviation colleagues are unsuccessful in convincing the department to consider legacy SBAS......then it will be largely useless for aviation until next gen avionics catch up....thats a loooooong way off. Also consider that aviation is the only industry sector that requires the legacy signal.....all other sectors are happy with SBAS II.
Leadsled, your first paragraph is correct. But you do need to clarify that it was the Australian Gov't that specifically rejected it because the Dept is anti SBAS....not AsA. Aviation will be a minor user of SBAS.
Your second paragraph is bollocks. Spreading unsubstantiated rumour does not help the cause.
