Abstract: In a concealed environment, the long term high accuracy navigation of vehicles is a challenging problem. The performance of traditional navigation methods, such as satellite navigation, inertial navigation and optical imaging navigation, is limited when navigation signals are obstructed or missions are prolonged. In order to cope with this problem, the neutrino navigation technology is studied, which involves a new principle to achieve motion state information of vehicles using natural neutrino signals where electromagnetic signals are denied. The necessity of neutrino navigation research for underwater or underground vehicles is explained. The research status of neutrino navigation technology is outlined, including neutrino radiation characteristics, neutrino detection methods and positioning algorithms. Furthermore, key technologies in the research of neutrino navigation are discussed. Finally, considering the research status and the application requirement, future trend and recommendation for the development of neutrino navigation technology are presented.
