报告简介

Global Navigation Satellite Systems (GNSSs) have revolutionised Positioning, Navigation, Timing and Atmospheric Sensing. Despite these tremendous achievements, important challenges remain, with new opportunities arising. In this presentation, after a brief review is given of the current state of positioning technology, a selection is given of the exciting challenges and opportunities that lie ahead of us. These concern the design of new GNSS constellations, the exploitation of terrestrial and space signals of opportunities, and the importance of GNSS integrity, in particular for liability-critical and safety-critical applications. In order to tackle GNSS integrity proper, important theoretical work still needs to be done. These challenges will be highlighted, in particular with a focus on interferometric mixed-integer models and the integrity description of positioning and deformation monitoring. These topics represent samples of fertile grounds for the typical researcher (PhD student and Postdoc alike) interested in the theory of geodetic data processing and modelling, and eager to take up a difficult challenge and/or looking for research opportunities that can make a difference.
