Session 15 - GNSS: How can the space weather community meet user requirements for navigation/communication at high latitudes?

Friday 22/11, 09:00-10:30

The decrease of sea ice in the Arctic has led to a substantial increase in maritime operations in this area. In the end of December 2018, the fishing vessel Northguider ran aground at 79° North in the vicinity of Svalbard in the middle of the polar night. Local rescue services managed to extract all personnel from the vessel, but where hampered by severe weather and degraded communication. Navigation and communication solutions at high latitudes suffer from a variety of factors such as sparse groundbased infrastructure, icing on hardware, limited availability of Satellite and Ground Based Augmentation Systems (SBAS and GBAS), limited visibility of geostationary satellites, degraded visibility during a substantial time of the year (polar night) and a variety of space weather related effects.

This sessions aims to present the challenges the user community experiences at high latitudes as well as existing and future solutions which the space weather community can provide.
