The Canadian Gravity Standardization Network (CGSN) provides a nationwide gravity datum defined by 5737 control stations systematically distributed throughout Canada. The adjustment of the CGSN is based on the International Gravity Standardization Network (IGSN71), therefore the datum definition is considered accurate to several tens of microgals. The maintenance and upgrade of the CGSN is managed through the National Gravity Database (NGDB) and relevant software.

Le Réseau de normalisation canadien de la gravimétrie (RNCG) constitue un système de référence gravimétrique défini par 5737 stations de contrôle systématiquement réparties à l'échelle du Canada. L'ajustement gravimétrique (RNGC71) et l'exactitude du système de référence est ainsi considérée de l'ordre de plusieurs dizaines de micro gals. La maintenance et l'amélioration du RNCG sont gérées par l'entremise de la Base nationale de données gravimétriques (BNDG) et du logiciel afférent.
