摘要：Cameras as a versatile sensor for position fixing and dead reckoning. New GNSS signals and systems that improve precision and combine with other technologies for jamming resistance and improved robustness. 3D mapping of cities and buildings that helps solve the puzzle of urban navigation. Context-adaptive navigation systems. Peer-to-peer positioning. An explosion of available sensors that can be combined for reliable pedestrian wayfinding. The art of navigation has never had so many tools to work with.
