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 Toitū Te Whenua and Geoscience Australia's existing network of global navigation satellite system (GNSS) tracking stations.
We tested 3 types of signals:
- Single frequency service SBAS (comparable to systems used in the US and Europe)
- Dual frequency-Multiple Constellation SBAS (a next-generation SBAS)
- 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 Toitū Te Whenua 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).
