1. Civil GPS Service Interface Committee International Sub Committee Meeting Melbourne, Victoria 10 th -11 th February 2003

2. GPS Augmentation - A Commercial View - Presented by OmniSTAR Pty Ltd

3. Overview History Lesson Current Systems Future Directions In Brief:

4. History Loran / Shoran Mainchain / HiFix Argo Radio navigation systems. Early 1970’s - Hyperbolic Systems Typically MF-HF (1-10mHz) frequencies with typical coverage to 400kms

6. History Trisponder Syledis Motorola Followed within a decade by Range - Range systems: Typically VHF-UHF frequencies still with coverage to 400kms and with improved position accuracy.

9. History Long range radio systems 2000kms developed Spot - Offshore Navigation Inc Also developed were: Private four satellite positioning system STARFIX - John E. Chance Gulf of Mexico Exploration for oil

11. History StartrackUDI- Marconi SkyfixRacal (Thales Navigation) GeorefGeoteam SARGASWestern Geophysical ORIONWimpol VeriposHF / Satellite The next decade saw the development of GPS augmentation systems. These systems were point to multipoint and conceived by Walter Blanchard.

12. History Generally providing sub-metre to 1,500kms Offshore construction for resource projects.

13. History Rack mounted mobile equipment Sophisticated operators Regional availability Offshore exploration and construction dependent These systems were characterised by:

15. History SkyFix - Thales Navigation STARFIX II - Fugro In the past decade this industry has further developed the GPS Augmentation systems available today. Development has been in two streams. Firstly, Offshore exploration and construction users

16. History Characterised by: Very high reliability and system redundancy Immediate disaster recovery systems Sophisticated user defined parameters for the position solution System quality assurance indications available to the user

17. Current Secondly, a stream for Onshore users OmniSTARFugro LandStarThales Navigation StarFireNavcom / JPL Characterised by: Low cost hardware solutions Simple operation Global availability

19. Benefits The Commercial GPS Augmentation industry provides significant benefits to the wider Australian community. Funding academic research Provides a “user benefit - user pays” environment for users in Australia Created an umbrella environment for Australian innovation Financial support to industry innovators

20. Benefits Examples of Australian Innovation: Satellite antenna design Visual guidance system in Agriculture GPS assisted steering for broadacre Rapid field asset mapping systems These research and development projects are now Australian exports.

22. Future The Future: Continued rationalisation of commercial GPS augmentation industry Significant investment in developing more accurate systems: - commercial - academic Participating in developing and commercialising new navigation networks: - Galileo Supporting development of new GPS applications: Material handling robotics by GPS Significant reduction in infrastructure costs
