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 ships. The accuracy and integrity provided by modern GNSS technology is now suitable for safe navigation in Australian waters.
