Canadian Active Control Point (ACP) Observational Data [Canada_GeoSC_ActvCntlPtObsData]
Canadian Active Control Point (ACP) observational data consists of dual-frequency calibrated satellite code and carrier phase observations derived from continuous tracking of GPS satellites ...
Canadian Base Network (CBN) of Monumented Survey Control [Canada_GeoSC_CdnBaseNtwkSurvCtl]
The Canadian Base Network (CBN) is a network of pillar monumented survey control points with forced-centering plates positioned three-dimensionally. They have GPS to centimetre-level ...
Canadian Electronic Distance Measurement (EDM) Calibration Baselines [Canada_GeoSC_EDMCalibrBaselines]
The Geodetic Survey Division (GSD) provides precise standard measurements at 44 Electronic Distance Measurement (EDM) calibration baseline sites across Canada. GSD is responsible for the ...
Canadian GPS Height Transformation Package (GPS-H) [Canada_GeoSC_CdnGPSHghtTransPkg]
The GPS Height Transformation Package (GPS-H) allows Global Positioning System (GPS), Differential Global Positioning System (DGPS) and Wide Area Differential Global Positioning System ...
Canadian GPS Validation Networks (GPS Basenets) [Canada_GeoSC_CdnGPSValidatnNtwk]
The need for a "truth" against which to test Global Positioning System (GPS) accuracy and precision has led to the establishment of 15 GPS validation network sites across Canada, also ...
Canadian Gravity Standardization Net (CGSN) [Canada_GeoSC_CdnGravityStndNet]
The Canadian Gravity Standardization Net (CGSN) provides a nationwide gravity datum defined by 5737 control stations, systematically distributed throughout Canada. The adjustment of the ...

Global GPS Satellite Clock Corrections [Canada_GeoSC_GlobalGPSSatClkCor]
GPS (Global Positioning System) satellite clock corrections are computed from observational data and final GPS satellite ephemerides and are typically available 3 to 6 days after the observations ...
Global Precise GPS Satellite Ephemerides [Canada_GeoSC_GlobalPreGPSSatEph]
Global Positioning System (GPS) satellite ephemerides are computed from the data collected at the Canadian Active Control Point (ACP) stations. This data is augmented by up to 44 globally ...
Global Single-Layer Ionospheric Model (SLIM) [Canada_GeoSC_GlobalSLIonosphMdl]
The daily ionospheric grid produced for the International GPS Service for Geodynamics (IGS), under the Ionosphere Associate Analysis Center (IAAC), is useful to single frequency users ...
