## Overview

- History Lesson
- Current Systems
- Future Directions

- In Brief:

## 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

## Slide 5

## 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.

## Slide 7

## Slide 8

## 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

## Slide 10

## History

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

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

## History

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

## History

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

- These systems were characterised by:

## Slide 14

## 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

## 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

## 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

## Slide 18

## 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

## 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.

## Slide 21

## 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
