Australasian Satellite-based Augmentation System (SBAS) test-bed trial

LINZ and Geoscience Australia explored the feasibility of SouthPAN in an 18-month trial focused on ten sectors in Australia and New Zealand.

The SBAS test-bed trial ran from January 2017 to January 2019. FrontierSI managed and delivered the project.  

The trial provided corrections to existing satellite navigation systems by analysing data using LINZ and Geoscience Australia's existing network of global navigation satellite system (GNSS) tracking stations.  

We tested three types of signals: 

  1. Single frequency service SBAS (comparable to systems used in the US and Europe) 
  2. Dual frequency-Multiple Constellation SBAS (a next-generation SBAS) 
  3. Precise Point Positioning (used for highly accurately position solutions with accuracy to within as a little as 10 centimetres). 

Data was transmitted to a processing facility, where the SBAS corrections were calculated and sent to the satellite up-link station and uploaded to the satellite. The geostationary satellite then broadcast the corrections over Australasia. 

Trial outcomes 

Testing three SBAS signals, the trial confirmed benefits, including improved GPS accuracy, improved signal integrity, and reduced commercial costs and infrastructure investment.

2021 EY SouthPAN Report 

In 2021 LINZ commissioned EY to review the costs and benefits of SouthPAN for New Zealand. This review confirmed several sectors are likely to benefit from its introduction, including:

  • livestock ($376.2m)
  • transport ($265.4m)
  • construction ($130m)
  • forestry ($33.7m)
  • horticulture ($23.1m)
  • utilities ($19.6m)
  • mining ($12m).
