Current Status
7
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

8
LBS

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

9
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

Current Issues

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

The Future

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