Abstract:Quantum sensing technology is to take photons, atoms and other quantum systems as the medium, and utilize quantum effect for achieving ultra-high-precision and sensitive physical quantity measurement to break through the standard quantum limit and bring about new opportunities for the breakthrough of the traditional navigation and positioning timing technology system based on the measurement of time and apace parameters. The quantum sensing changes the perception mechanism of navigation sensors in navigation systems, enables high-precision observation of space-time parameters, and utilizes the non-classical characteristics of quantum systems for achieving sage and reliable transmission and detection of navigation information, and enhancing navigation confrontation capabilities. As the main testing ground for quantum sensing technology, the quantum navigation technology is in the ascendant ,new navigation parameter quantum sensing technology and functional device are constantly emerging, and the measurement performance is changing with each passing day, this paper analyzes the physical principles of different quantum sensing technologies and devices, discusses the development direction and research progress of quantum navigation technology ,and looks forward to its future development rends and combined navigation methods. With the advancement of quantum sensing technology, high-precision, anti-jamming and practical high-performance quantum navigation systems will have broad application prospects in the social, economic, and military fields.
