This project will establish a collaborative framework to coordinate and undertake user testing of SBAS in Australia and New Zealand. The research will also provide a benefit analysis of SBAS technology to Australia and New Zealand.

The CRCSI will lead the industry program which evaluates applications on the newly announced SBAS testbed. CRCSI partners, Geoscience Australia and Land Information New Zealand (LINZ) together with three global companies GMV, Inmarsat and Lockheed Martin will implement the SBAS testbed through a two-year project to evaluate three positioning signals for improved accuracy and integrity over Australia and New Zealand.

The signals are

  • The current offering provided in Europe and the US (L1 Legacy signal)
  • A new dual frequency signal to be tested for the first time in both Australia and New Zealand (L5 Dual-Frequency and Multi-Constellation Signal)
  • High-precision Precise Point Positioning (PPP) navigation corrections where decimetre level accuracies at user level are expected.


In simple terms the SBAS satellite provides a cost effective way to improve GPS signals from around 5 metres in accuracy to less than 1 metre.

Widespread adoption of improved positioning technology has the potential to generate $73 billion in value to Australia alone by 2030.

Further information about this research can be found on the Geoscience Australia website. News and current details about the National Positioning Infrastructure can be obtained here.
