History
Radio navigation systems. Early 1970s -
Hyperbolic Systems

• Loran / Shoran
• Mainchain / HiFix
• Argo

Typically MF-HF (1-10mHz) frequencies with
typical coverage to 400kms

History
Followed within a decade by Range - Range systems

• Trisponder
• Syledis
• Motorola

Typically VHF-UHF frequencies still with coverage
to 400kms and with improved position accuracy.

History
The next decade saw the development of GPS
augmentation systems. These systems were point to
multipoint and conceived by Walter Blanchard.

• Startrack UDI- Marconi
• Skyfix Racal (Thales Navigation)
• Georef Geoteam
• SARGAS Western Geophysical
• ORION Wimpol
• Veripos HF / Satellite

12
History
Generally providing sub-metre to
1,500kms Offshore construction for resource
projects.
13
History
These systems were characterised by

• Rack mounted mobile equipment
• Sophisticated operators
• Regional availability
• Offshore exploration and construction dependent

History
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

• SkyFix - Thales Navigation
• STARFIX II - Fugro

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

• OmniSTAR Fugro
• LandStar Thales Navigation
• StarFire Navcom / JPL

Characterised by

• Low cost hardware solutions
• Simple operation
• Global availability

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.

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
