This SBAS Testbed is a satellite based positioning infrastructure that will available from June 2017 – January 2019. CRCSI is coordinating and undertaking user testing of SBAS in Australia and New Zealand in conjunction with a benefit analysis of SBAS technology to Australia and New Zealand.

CRCSI partners, Geoscience Australia (GA) and Land Information New Zealand (LINZ) together with three global companies GMV, Inmarsat and Lockheed Martin have implemented the SBAS testbed to evaluate three positioning signals for improved accuracy and integrity over Australia and New Zealand.

Approximately 20 projects across aviation, agriculture, consumer, construction, maritime, rail, resources, road, spatial and utilities sectors in Australia and New Zealand are currently being finalised and will be starting soon.

Projects in identified sector gaps in Australia or New Zealand are being sought to be trialled on the SBAS testbed. Companies, governments and research organisations are invited to submit an expression of interest (EOI) ideally addressing applications in one or more of the following specific key sectors: agriculture (horticulture), construction, resources, utilities, and consumer (including any health and welfare applications). More information including the short EOI form can be found here.

The positioning signals for evaluation are:

  • The current L1 Legacy service similar to that available in the United States (WAAS), Europe (EGNOS), Japan (MSAS), India (GAGAN) and Russia (SDCM).
  • A second-generation Dual Frequency Multi Constellation (DFMC) signal which will provide improvement over the legacy signal in a number of areas. This signal has not been tested anywhere in the world.
  • High-precision Precise Point Positioning (PPP) corrections with expected decimetre accuracies at user level.

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.

This trial is supported by a $12 million investment from the Australian Government as announced in January 2017 with a further $2 million from the New Zealand Government.
