Abstract

Global Navigation Satellite Systems (GNSS) has opened up a wide spectrum of applications, providing unprecedented social, economic, technological and environmental benefits. The ever-increasing dependence on GNSS has triggered more and more concerns about the service integrity guarantee of GNSS navigation solutions. Navigation integrity is indispensable in safety critical applications such as civil aviation and for an emerging field of the so-called “liability critical” applications where navigation performance problems can generate significant legal or economic consequences (or liabilities) when not properly identified. To address the satellite navigation integrity risks, two strategies have been proposed: a) GNSS Integrity Channel (GIC); b) Receiver Autonomous Integrity Monitoring (RAIM). A RAIM procedure is self-contained and can be used as an ultimate integrity monitor. This seminar will cover the navigation integrity concept; fundamental functional and stochastic models used in satellite navigation; the concept frameworks and algorithms of classic RAIM and Advanced RAIM; recent research activities and future trends in satellite navigation integrity monitoring.

Speaker

Jinling Wang is Associate Professor of Surveying and Geospatial Engineering, in the School of Civil and Environmental Engineering, UNSW (University of New South Wales) Australia. His major research interests are in the areas of navigation and geospatial mapping with multi-sensors, such as GNSS, INS, cameras. He is a Fellow of the Royal Institute of Navigation (RIN), UK, and a Fellow of the International Association of Geodesy (IAG) as well as the Japan Invitation Fellow awarded from the Japan Society for Promotion of Science (JSPS).
