Discontinuation of the Differential GPS Service

The General Lighthouse Authorities are planning to shut down the Differential Global Positioning System (DGPS) from 31st March 2022. The DGPS service is a land-based enhancement to GPS which was designed to increase the accuracy of the system during the period when an intentional location error was introduced into GPS to make it less accurate. This error was removed in 2000.
