Current Status
![Page 7: Victorian Update CGSIC July 2006 Peter Ramm peter.ramm@dse.vic.gov.au.](https://reader030.fdocuments.in/reader030/viewer/2022032604/56649e605503460f94b5aac8/html5/thumbnails/7.jpg)
Policy Framework
• Continues to be important– Provides the policy context for
positioning infrastructure– Within Policy, positioning is becoming
more important• Facilitates other activities• Exposes quality issue in other spatial DB• Coordination of infrastructure

LBS
• Planned to have about 0.5 m accuracy real time solution over Vic– Delivered Dec 2004

Implications For Vic
• For all practical purposes GPSnet is the realisation of the geodetic datum in Vic
• Now have Reg 13 Certificates on 18 Base Stations

Victorian GPS Base Station Network

Current Issues
![Page 13: Victorian Update CGSIC July 2006 Peter Ramm peter.ramm@dse.vic.gov.au.](https://reader030.fdocuments.in/reader030/viewer/2022032604/56649e605503460f94b5aac8/html5/thumbnails/13.jpg)
Current Issues
• Networks solutions not quite there– Inter Station Distance too small– Poor understanding of how they work– Low sat numbers a problem at times
• Driving changes in spatial data– Increased spatial accuracy in mapping
• Coordination • Multiple software systems on the one network• Hardware Costs down, but operators still have high
costs• CRC SI• NCRIS

The Future
• State wide• Real time• 2-3 cm Horiz
Accuracy• 3-5 cm Vertical
