The Global Satellite Navigation Systems (GNSS) are widely applied not only for positioning and localisation (traffic, personal devices, surveying and navigation) but also for natural hazards (subsidence and landslide observing, tsunami alert, etc.) as well as environmental monitoring (water vapour probing, total electron content estimation, soil moisture). They are also becoming part of many communication devices. The student will learn how to process the observed direct and indirect signals for positioning, speed determination as well as environmental applications.
