Reliable navigation and positioning are becoming imperative in more and moreapplications for safety-critical purposes, public services and consumer products. A robust localization solution, which will be available continuously is needed regardless of the specific environment, i.e., outdoors and indoors, and on different platforms such as stand-alone navigators and mobile devices. ICL-GNSS addresses the latest research on wireless and satellite-based positioning techniques to provide reliable and accurateposition information with low latency. The emphasis is on the design of mass- market navigation receivers and related tools and methodologies.
