G05: Studies of Irregularities and Scintillation (1)

Tuesday, August 19  08:00-09:20,  Room #14

Session Chairs: Hal Strangeways, Biagio Forte

This session seeks to review the latest developments in the study of ionospheric irregularities and scintillation. Papers that focus on the problems of scintillation on satellite based systems such as GNSS (Global Navigation Satellite System) at both high and equatorial latitudes will be particularly welcome. The sessionís scope will also include relevant theory, observations of beacon and GNSS satellites over both satellite to ground and satellite to satellite links and statistical descriptions of scintillation together with mitigation methods and strategies (both hardware and software) to model and combat its effect.
