AMSA informed that vessels navigating in Australian and New Zealand waters can now access a Satellite-Based Augmentation System (SBAS) called SouthPAN.
he joint Australia and New Zealand government operated SBAS is named Southern Positioning Augmentation Network or SouthPAN.
SouthPAN will improve the accuracy, availability and integrity of PNT information for users in the region. It now delivers early Open Services, free of user charges.
SouthPAN provides accurate, reliable and instant augmentation of PNT information across all of Australia and New Zealand. For example, the horizontal accuracy provided is several times better than the current unaugmented GNSS accuracy of about 10 metres.
With early Open Services now live, Australia and New Zealand are working towards full Open Services capability and an International Civil Aviation Organization (ICAO) certified Safety-Of-Life Services (primarily for aviation use) by 2028.
Operators will need a SBAS-enabled GNSS receiver to use SouthPAN’s three early Open Services. It is likely such receivers will need to be configured to receive the correct types of messages from SouthPAN.
You should check with the manufacturer of your receiver to know more about its capabilities
The L1 SBAS early Open Service is available within the light blue area shown in the diagram below.
The Dual Frequency Multi Constellation (DFMC) and Precise Point Positioning (PVS) early Open Services are available within the dotted lines.
