 Zusammenfassung: At high geomagnetic latitudes, increased phase scintillation in GNSS can be associated with strong external magnetic field signatures. High phase scintillation can lead to errors in positioning and in worst case, cause loss of contact to the navigation satellites. By monitoring the geomagnetic field in the Arctic through a chain of ground magnetometers a correlation between the GNSS phase scintillation and high geomagnetic activity can be investigated. This presentation addresses the link between GNSS phase scintillation and magnetospheric substorms in Greenland and the possibility of creating an alert system for GNSS users in the Arctic regions. The geomagnetic data presented are 1 Hz data from the west coast ground magnetometer chain in Greenland. Through the magnetic measurement the equivalent currents in the ionosphere is found along side with the polar electrojet boundaries. This shows that the polar electrojet boundaries and the equivalent current are correlated with high GNSS phase scintillation in Greenland.
