Posted through the URSI-Commission-G Mailing List: Special Session on Ionospheric Effects on Aviation Systems at IES2008

Dear Colleagues: 
     On behalf of the IES2008 steering committee and Ms. Patricia Doherty, the Special Session Convener, we are pleased to announce a special session at IES2008. A short description follows. The published abstract deadline is 1 February 2008. IES2008 is to be held in Alexandria VA on May 13-15, 2008. A flyer is attached in PDF form. 
 
Ionospheric effects on on Aviation Systems: Chaired by Patricia Doherty, Boston College 

This session will be dedicated to ionospheric effects on aviation, navigation, and communication radio systems. These systems may include Satellite-Based Augmentation Systems (SBAS), Ground-Based Augmentation Systems (GBAS), satellite communication and shortwave voice and data communication systems. The FAA's WAAS system was the first SBAS deemed operational in July 2003. Since that time, the greatest impacts on WAAS availability have been the extreme solar storm events. As we enter a new solar cycle, solar storms will continue to be source of concern for SBAS and GBAS systems worldwide. Solar storms will further confront aircraft operating in the polar region, where communications blackouts and potential radiation hazard to passengers result in costly route changes and flight delays. Augmentation and aircraft systems planned to operate in the low latitude regions will be seriously challenged by the extreme ionospheric dynamics in the near equatorial ionosphere. As the aviation industry becomes more dependent on satellite based navigation and communication systems, it is important to assess the impending worldwide challenges of solar cycle 24. This session invites abstracts related to ionospheric assessments, algorithm development, performance assessments and program status for all navigation and communication radio systems.
