The International Workshop on GNSS Ionosphere (IWGI2019) - Theory, Algorithms, Modelling and Applications is jointly sponsored by the German Aerospace Center (DLR) and Shanghai Astronomical Observatory(SHAO), CAS, China.

Ionospheric refraction is considered as one of the major accuracy limiting factors in microwave space-based geodetic techniques such as the GPS (Global Positioning System), SLR (Satellite Laser Ranging), VLBI (Very Long Baseline Interferometry), DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) and satellite altimetry. All trans-ionospheric microwave signals are subject to ionospheric refraction and subsequent delays in the travel time. The use of multi-frequency and multi-GNSS observations enables precise remote sensing of the ionosphere and thus mitigation of ionospheric effects in numerous applications. This leads to unprecedented accuracy improvement in GNSS applications. Moreover, precise time and frequency transfer may lead to new applications in navigation, Earth observation, solar system science and telecommunications.

The International Workshop on GNSS Ionosphere 2019 (IWGI2019) will provide a platform for scientists and engineers to communicate and exchange their views on ionospheric theory, methods, technologies, applications and future challenges. The workshop is open to all scientists who may have the latest results and developments in ionospheric scintillation, reconstruction, modelling, monitoring techniques and prediction methodologies as well as ionospheric propagation effects on microwave space-based geodetic techniques such as the GPS, SLR, VLBI, DORIS etc. and their mitigation using multi-frequency, multi-sensors observations. Space weather impact studies on Earth/Space systems and infrastructures are also welcome.
