Abstract: All-weather,high anti-interference,and high concealment positioning,navigation and timing without exchanging information with the outside world can be achieved by autonomous navigation.Cold atom interferometry is with ultra-high sensitivity and stability due to its characteristics of matter wave and absolute measurement,and is expected to create an autonomous high-precision navigation system integrating inertial navigation,gravity and gravity gradient map matching aided navigation,and applied to long-term voyage carriers.Based on the configuration of atom interferometry,the research on cold atom sensors in recent decades over the world is summarized,and the technical schemes is analyzed,so as the selection of schemes suitable for the autonomous navigation is provided.
