The next UNB Physics Department Seminar will take place on Thursday, Nov. 1, from 1:15 - 2:15 p.m., in the IUC Physics/Admin Bldg, 204 and will feature Anton Kashcheyev, UNBF Physics, speaking on "Global Ionospheric Maps."

“The ionosphere is the ionized layer of the Earth’s upper atmosphere that extends from 60 km to few thousands kilometers in altitude. This layer is affecting the propagation of electromagnetic signals, therefore it plays an important role in satellite-based navigation. In particular, for single frequency GNSS receivers the ionospheric delay is one of the most significant error sources impacting the navigation accuracy. To correct for the ionosphere a number of different ionospheric models have been implemented and used by the scientific and engineering communities. One of such modelling techniques is Global Ionospheric Maps (GIM) of vertical electron content.  In this talk, the details of Global Ionospheric Maps produced by different Ionospheric Associated Analysis Centers will be discussed. The statistical analysis of their differences as well as the possible methods to access their accuracy will be presented.”

Please join us for Colloquium tea in P203 beforehand.
