| Abstract: |
| Inertial technology is widely used in navigation, positioning and control of various carriers on sea, land, air and space. By sorting out the papers of inertial technology related conferences such as 2022 IEEE International Symposium on Inertial Sensors and Systems, DGON Inertial Sensors and Systems Symposium, IEEE 35th International Conference on Micro Electro Mechanical Systems(MEMS) and the 29th Saint Petersburg International Conference on Integrated Navigation Systems (INS), as well as the dynamic information disclosed by relevant institutions in the field of inertial technology, this paper summarizes the development status of inertial systems and inertial sensors such as optical gyroscopes, MEMS gyroscopes, hemispherical resonance gyroscopes (HRGs), accelerometers and the emerging quantum or atomic sensors. Lastly, the development trend of inertial technology is analyzed and prospected. Currently, research in the field of inertial technology mainly focuses on miniaturization, improving accuracy, and reducing cost. Among them, optical gyroscopes are more mature and more emphasis on miniaturization related research; MEMS gyroscopes are committed to breakthroughs and developments of navigation grade performance; HRGs mainly focus on the exploration of reducing the manufacturing cost of high-end products. |
