Session 6 - Space Weather effects on GNSS and precise positioning

Claudia Borries, J. Berdermann (German Aerospace Center)
Tuesday 15/11, 10:00-13:00

One of the most dominant error sources for GNSS applications is the Ionosphere. It does not only affect standard GNSS applications and differential GNSS but also high-accuracy demanding applications like the Precise Point Positioning (PPP) and Real Time Kinematics (RTK). Next to the common signal delay, the Ionosphere can cause e.g. loss of lock in case of scintillation events or produce hazardous misleading information in augmentation systems due to strong ionospheric gradients. Higher order ionospheric effects limit the PPP. Today, a large variety of products and models is already in place to reduce the ionospheric error on GNSS applications. However, often there is still a gap between the currently available products and their actual usage in GNSS applications. This session aims to communicate the status of the currently available techniques for ionospheric error correction. Reports on the impact of the ionosphere to GNSS application and the formulation of derived requirements on ionospheric services are very welcome. Furthermore we also encourage the presentations of available products for mitigating the ionospheric impact on GNSS as well as related research on forecast and modelling of the Ionosphere.
