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

This documentation provides instructions for configuring Global Navigation Satellite System (GNSS) receivers to use the SouthPAN Open Services.

SouthPAN Early Open Services

SouthPAN augments satellite positioning services to provide improved Position, Navigation, and Timing (PNT) capabilities for End-Users in Australia and New Zealand. These capabilities are made available to End-Users through their GNSS-enabled devices and dedicated internet services.

The SouthPAN Early Open Services include:

• L1 SBAS providing augmentation of the GPS L1 C/A, delivered on the L1 frequency
• DFMC SBAS providing augmentation of the GPS L1 C/A, GPS L5, Galileo E1, and Galileo E5a signals, delivered on the L5 frequency
• PPP via SouthPAN (PVS) providing augmentation of the GPS L1 C/A, GPS L5, Galileo E1, and Galileo E5a signals, delivered on the L5 frequency. PVS Open Service will be migrating to the new L5b navigation signal in 2027/28.

SouthPAN Early Open Services are available now via navigation Signals-In-Space and Data Access Service (DAS) over the internet. These services are provided to non-Safety-of-Life users as the infrastructure for the Safety-of-Life Service is deployed and certified. Service performance will improve progressively as infrastructure upgrades are deployed, offering greater resilience, reliability and redundancy.

GNSS equipment manufacturers, applications developers, and end-users should use the SouthPAN Service Definition Document and Disclaimer to implement the early Open Services from SouthPAN on their devices:
