| 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 Guards efforts to modernize marine navigation services and find alternatives to aging DGPS infrastructures. Todays 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 Guards 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. |
