Maritime Navigation
The future of the CCG Differential Global Positioning System (DGPS)
• Due to its age and the needs for replacement, the CCG conducted an options analysis for the future of the CCG
DGPS service.
• CCG will be discontinuing the Canadian DGPS by the end of 2022. All 19 sites will be shut down
simultaneously.
• Between now and Fall of 2022, CCG will continue to inform stakeholders and communicate in preparation for
the shutdown date.

Description
On December 15th, 2022, the Canadian Coast Guard will permanently discontinue the provision of its DGPS service across Canada.
Discontinuing this service aligns with Coast Guard’s efforts to modernize marine navigation services and find alternatives to aging DGPS infrastructures.
Today’s GPS meets the needs of international Position, Navigation and Timing (PNT) requirements. Further, for mariners in Canadian waters, there is no carriage requirement for ground- or space-based augmentation capability onboard vessels for Global Navigation Satellite Systems (GNSS).
Modern GNSS receivers can use the Wide Area Augmentation System (WAAS) as a viable alternative to DGPS. Coast Guard’s technical review of PNT solutions for Canada, and a study of the performance of WAAS found coverage to be excellent throughout Canada, including up to 72 degrees north latitude in the Arctic.
