Current Activities

• GNSS Vulnerability Seminar, 8 July 2005
• The seminar was held to alert the civil-GPS user
  community addressing concerns of denial of
  service by intentional or unintentional
  interference and sought to raise awareness of the
  vulnerability issues associated with
  GPS-dependence. The presentations are available
  at http//www.agcc.gov.au/events/agcc_seminar_0807
  05.aspx.
• Meeting of AGCC Chair with US GPS representatives
• In May 2005, the AGCC Chair, Prof Don Sinnott,
  met with representatives of a number of Federal
  Departments (Transportation, Commerce, State),
  NASA and the US Coast Guard Navigation Centre for
  reciprocal briefings on GPS matters. A move from
  a technology focus (GNSS) to a focus on PNT
  services that are delivered by technologies
  including, but not limited to, GNSS would appear
  to be in harmony with the US policy.

Current Activities - 2

• Relationships between Australia and the US on
  civil GPS
• A form of words describing elements of a possible
  Australia/US civil agreement on GPS is being
  worked through by AGCC representatives and US
  Department of State officials but no formal
  process has yet been initiated.
• AGCC Meeting Reports
• A summary of the outcomes of the AGCC meetings
  are available on its website at www.agcc.gov.au.

National Activities

• Airservices Australia
• The Australian air navigation service provider
  signed a contract with Honeywell International 16
  June 2005 to develop a ground-based regional
  augmentation system (GRAS) in accordance with
  ICAO Standards and Recommended Practices. An
  operational GRAS is expected to be approved for
  use in late 2007.
• Airservices Australia is leading an international
  group to implement a Honeywell beta GBAS Cat-1
  system into Sydney airport by mid October 2005.
  Qantas took delivery of the first four B-737NG
  aircraft fitted with Ground Based Augmentation
  System (GBAS) Category 1 avionics in May 2005.
  An additional five aircraft will be delivered in
  October 2005 and 12 A-380s will be delivered with
  the GBAS Cat-1 avionics.
• Airservices also intends to certify a GBAS
  Category 1 satellite landing system by the end of
  2007

National ActivitiesGeosciences Australia

• The Australian Regional GPS Network (ARGN) now
  has 21 permanent GPS tracking stations in
  Australia and Antarctica (as well as Macquarie
  Island in the Southern Ocean and Cocos Island and
  the Christmas Islands in the Indian Ocean).
  Outputs continue to improve in quality and
  reliability.
• Continues to run a number of GLONASS receivers
  co-located with IGS base stations on mainland
  Australia and contributes these data routinely to
  the International GLONASS Service (IGLOS)
• Continuous and episodic GPS data has been
  acquired from a number of international agencies
  to examine the effects of the December 2004
  tsunami off Sumatra.
• Manages the CGPS component of the South Pacific
  Sea Level and Climate Monitoring Program.

National ActivitiesGeosciences Australia

• The on-line GPS processing service, AUSPos,
  continues to attract users worldwide. This free
  service uses a processing strategy compliant with
  IGS standards, constraining the nearest three IGS
  sites with the IGS products (satellite orbits,
  earth orientation parameters and coordinates) to
  produce results with an accuracy of a few
  centimetres on a global basis.
• The Real Time GPS data product (1Hz data) is now
  available from 10 of the ARGN sites. This data is
  being streamed to National Resources, Canada
  (NRCan), (with an average delay of 0.9sec.) who
  then use the information to produce global orbits
  for their real time positioning service. The data
  is available on the GA web site in the form of 15
  minute RINEX files for use by surveyors using
  kinematic positioning. It is also sent to the
  International GNSS Service (IGS) and the Korean
  Global Data Centre to be included in the global
  analysis and production of rapid orbit products.
  Real Time Meteorological data is now also
  available from several ARGN.
