Analyzing the current situation of quantum navigation technology system

With the continuous development of quantum information science and technology, quantum navigation equipment has attracted extensive attention at home and abroad due to its higher measurement accuracy, smaller equipm ent volume and wider application areas. It has gradually become an emerging technology to improve the core capability of the next generation of position and navigation equipment and may be put into use before 2030, and become an core realm to lead the following development of position and navigation. This paper combs the technical system, key development directions and research status in the field of quantum navigation, and gives follow-up development suggestions, which plays a promoting role in the development of quantum navigation technology.
