SWWT Topical Group "Ionospheric Effects"
The ionosphere is a critical part of the propagation medium for many types of radio transmissions. Ionospheric reflections of High Frequency (HF, 2-30 MHz) transmissions allow communications over long distances without using relay stations or satellite links. Furthermore, HF radar allows surveillance beyond the line of sight. Higher frequency radio signals propagate through the ionosphere allowing satellite telecommunication links and satellite navigation. However, the varying characteristics of the ionosphere can cause significant disturbances in the radio signals (i.e. phase and amplitude scintillation) and cause errors or breaks in the respective services.
The Ionospheric Effects Topical Group is a forum for discussion and exchange of information, ideas and thoughts regarding ionospheric modelling, observations and mitigation techniques. The group also addresses topics related to ionospheric services for the end user community; these include new approaches for warning users when conditions in the ionosphere may compromise the integrity of services based on trans-ionospheric radio signals.
