The Canada-wide DGPS (CDGPS) Service is a program designed to provide GPS users in Canada with free access to GPS corrections. The Service will provide metre-level solutions consistent with the national reference frame NAD83(CSRS), allowing users to directly relate their data holdings with the primary alignment layer of the GeoConnections Framework Data Node. The provincial governments, the Territory of Nunavut, and the federal government are jointly funding the development of the satellite radio receiver and infrastructure to provide users access to Natural Resources Canada (NRCan)’s GPS correction signal (GPS·C) to be broadcast to all GPS users via the MSAT satellite. This paper will provide the background and status information of the CDGPS initiative scheduled for public availability late summer of 2002.
