GPS·C, short for GPS Correction, is a Differential GPS data source for most of Canada maintained by the Canadian Active Control System, part of Natural Resources Canada. When used with an appropriate receiver, GPS·C improves real-time accuracy to about 1-2 meters, from a nominal 15 m accuracy.
Real-time data is collected at fourteen permanent ground stations spread across Canada, and forwarded to the central station, "NRC1", in Ottawa for processing.

GPS·C information is currently broadcast Canada-wide on MSAT by the CDGPS, short for Canada-Wide DGPS Correction Service. CDGPS requires a separate MSAT receiver, which outputs correction information in the RTCM format for input into any suitably equipped GPS receiver. The need for a separate receiver makes it less cost-effective than solutions like WAAS or StarFire, which receive their correction information using the same antenna and receiver.
