Canadian Marine Differential Global Positioning System (DGPS) Broadcast Standard

Canadian Coast Guard

Last updated: October 11, 2007

The Canadian Coast Guard Differential Global Positioning System (DGPS) Broadcast Standard is a reference document that specifies the format; information content, modulation parameters, coverage area, and use of the signal that is broadcast from a network of Canadian Coast Guard operated marine radio beacons. This network provides coverage to Canadian coastal areas, major waterways, Vessel Traffic Services zones and ports. It also overlaps US DGPS coverage of contiguous waters.

This Standard also specifies the system performance that can be achieved with the use of proper DGPS user equipment. Key performance and functional elements essential for the user equipment suite are addressed.

For questions or comments regarding the CCGDGPS Standard, please contact the CCG DGPS Office.
