The future of AMSA’s DGPS service

15 November 2019

On 1 July 2020, the Australian Maritime Safety Authority (AMSA) will discontinue its Differential Global Positioning System (DGPS) service.

The increased accuracy of GPS and introduction of other global positioning constellations including GLONASS, GALILEO and Beidou, mean that AMSA’s DGPS service is no longer needed.

Today, GPS is one of several Global Navigation Satellite Systems (GNSS) that provide accurate Position, Navigation and Timing (PNT) information to ships fitted with modern GNSS receivers.

Modern GNSS receivers also offer inbuilt integrity monitoring of positioning, navigation and timing information. Such receivers are now a standard installation on board most vessels.
