The effects of ionospheric variability on GNSS covers signal group delay, scintillation and Faraday rotation. In recent years, the investigation of these effects has increased dramatically in those countries that are under the low latitude ionosphere. The scope of this session is to encourage scientists working in the field to present their most recent results on the low latitude effects on GNSS operations.</span></p><p class="MsoNormal" style="margin-bottom:0.0001pt;background-image:initial;background-repeat:initial"><span style="font-family:'Times New Roman',serif"> </span></p><p class="MsoNormal" style="margin-bottom:0.0001pt;background-image:initial;background-repeat:initial"><span style="font-family:'Times New Roman',serif">We sincerely hope to see you in Gran Canaria.
