摘要：

Ionospheric activity is a significant concern for reliable operation of GPS positioning applications, particularly at high latitudes. In order to monitor high latitude ionospheric activity for GPS users, researchers at the University of Calgary have installed the Canadian GPS Network for Ionosphere Monitoring (CANGIM). This network has been operational since 2003 and consists of a number of reference stations, each equipped with a specialized GPS receiver capable of providing near real-time observations of ionospheric parameters and raw GPS data. Potential exists to provide ionospheric warnings and near real-time measures of associated impacts on positioning and navigation applications for GPS users. This paper provides an overview of ionospheric limitations for high latitude GPS users, and describes the ionospheric monitoring services developed for the CANGIM.
