GPSGuided wrote:How are they going to do that when resolution is dictated by countries that host satellite positioning systems? Are we donating this money to the US? I understand the US is scheduled to upgrade their GPS network to match the other three global systems which come with sub-meter resolution in the base spec. Not sure what infrastructure our federal govt can invest to alter.

Spatial data has been under pressure to produce 'more accurate' data for a while now.
Be interesting when GDA 2020 hits the deck.

I don't think the budget announcement is unexpected, more a politically timed event to aid their well being.

Thanks for the link. So yeah the bulk of the money is for SBAS, so separate/adjunct to existing satnav networks, but some is also being spent on terrestrial ground stations. Interestingly the statement also said accuracy would improve 10cm to 3cm within mobile coverage areas, which suggests a sort of GBAS implementation via mobile networks as well?michael_p wrote:Might be money to improve the CORS Network across the country. Currently CORS is 20cm, getting this down to 10cm would be good for surveyors et al.
