Mitigation of ionospheric effects on GNSS

Abstract

The effects of the ionosphere remain one of the main factors which limit the precision and the reliability of many GNSS applications. It is therefore indispensable on the one hand to improve existing mitigation techniques and on the other hand to assess their remaining weaknesses. Mitigation techniques depend on the type of application considered. Therefore, specific mitigation techniques have to be developed. The paper summarizes work performed on this topic in the frame of WP 3.2 «Mitigation techniques» of COST 296.
