- Use of GPS in agriculture, why the slow pick-up
- Potential interference sources to GPS in Australia
-  Nomination of two judicial GPS evidence sources
- National Measurements Laboratory

-  Legal issues with adjoining use of GPS between States

## Maritime

** **Concern by commercial providers of DGPS vs Gov’t DGPS
- Resolved
-  Australian Maritime Safety Authority DGPS network nearing completion
** **
-  Recent incidents provided a good example of having to know exactly where our territorial limits are in relation to an island to our north west
** **

## Land

*** *****GPS timing used at the Olympics 2000 for the first time**
** ****Multimodal use of GPS - freight tracking from arrival by sea to delivery by rail and vehicle**
** ****All taxis in capital cities now fitted with GPS (more efficient 3 mins response in Sydney, higher security for drivers)**
** ****Emergency services uptake increasing**
** ****Emergency telephone system (000 not 911) usage**
** ****State wide DGPS now in Victoria, NSW, others in planning**

## Aviation

-  >200 GPS approaches now in use
-  GBAS Cat 1 expected in 2003 at Sydney International
-  GRAS
- draft SARPs to ICAO GNSS Panel Working Group in Oct 2001
- RTCA has GRAS on its work program
-  TSO-146 equipment most likely way ahead as it provides best benefits to increase IFR usability
- Need a TSO 146 box to test
-  ADS trials using TSO 129 GPS start Oct 2001
-  Satellite constellation
- PRN 22 impacted RAIM throughout Australia
- No known problems from last PRN 19 test
- Errors in NANU messages still causing problems

## General

** ****US Government’s (FAA) WAAS in Asia Pacific**
- unclear as to the aims

- briefings in Kuala Lumpur Malaysia Aug 01
- very useful and needed
- Be aware of post SA accuracy etc being collected by ICAO
- Mixed signals as to why two separate US Departments are providing information on GNSS in Asia Pacific

## General

** ****Need a realistic signal specification**
- must recognise true GPS performance
** ****Australia’s request for GPS Fault Analysis now into its 4th year with still no formal response**
- Information exists
- Needed for any WAAS, GBAS, GRAS operational approvals
** ****Both needed for Safety Cases and for aviation certification processes**
