%T The Four Key Challenges of Advanced Multisensor Navigation and Positioning
%U https://discovery.ucl.ac.uk/id/eprint/1427143/
%X The next generation of navigation and positioning  systems must provide greater accuracy and reliability in a range  of challenging environments to meet the needs of a variety of  mission-critical applications. No single navigation technology is  robust enough to meet these requirements on its own, so a  multisensor solution is required. Although many new navigation  and positioning methods have been developed in recent years,  little has been done to bring them together into a robust, reliable,  and cost-effective integrated system. To achieve this, four key  challenges must be met: complexity, context, ambiguity, and  environmental data handling. This paper addresses each of these  challenges. It describes the problems, discusses possible  approaches, and proposes a program of research and  standardization activities to solve them. The discussion is  illustrated with results from research into urban GNSS  positioning, GNSS shadow matching, environmental feature  matching, and context detection.
