About the SouthPAN partnership

The Southern Positioning Augmentation Network (SouthPAN) is a joint initiative of the New Zealand and Australian Governments that provides Satellite-Based Augmentation System (SBAS) services for New Zealand and Australia.

Toitū Te Whenua Land Information New Zealand and Geoscience Australia are working in collaboration, under the Australia New Zealand Science, Research and Innovation Cooperation Agreement (ANZSRICA), to develop, deploy and operate SouthPAN as the first SBAS in the Southern Hemisphere. 

New Zealand and Australia have jointly explored the feasibility of SouthPAN. Between 2017 and 2019, a trial established that SouthPAN improved GPS accuracy, improved signal integrity, and reduced commercial costs. 

Find out more about the SBAS test bed trial and read the EY economic benefits report.

Toitū Te Whenua and Geoscience Australia are jointly responsible for SouthPAN. The operational capability of SouthPAN is delivered by Lockheed Martin Australia, GMV and Inmarsat Australia.

Building the SouthPAN infrastructure

Inmarsat Australia has been contracted by Geoscience Australia as part of the SouthPAN partnership to broadcast SouthPAN services from a new Inmarsat I-8 satellite. 

The new SouthPAN satellite service (SouthPAN GEO Payload 01, known as SGP-01) on the Inmarsat I-8 satellite will replace the Inmarsat satellite I 4F1 acquired as part of the SouthPAN test-bed trial.

 SouthPAN signals are expected to broadcast services over a new Inmarsat I-8 satellite navigation system for 15 years, starting in 2027. 

A second new SouthPAN satellite service is also being procured to provide redundancy and resilience in SouthPAN. This will ensure continuous broadcast of SouthPAN services, enabling the development and use of critical applications relying on SouthPAN. 

The ground segment of SouthPAN, including the network of ground reference stations and satellite uplink facilities, is being built by Lockheed Martin Australia as part of their separate contract with Geoscience Australia and Toitū Te Whenua Land Information New Zealand.
