| nertial technology product is the core bottleneck technology of navigation and control, which restricts the progress and development of high precision navigation and control technology in China. Especially, with the advent of the digital age, it is more self-sensitive and widely valued. With the emergence of traditional mechanical gyroscopes, optical gyroscopes, micro-electro-mechanical gyroscopes and atomic gyroscopes, technological advances have led to the transition and upgrading of products. High precision, low cost, miniaturization and high reliability represent the consistent pursuit of the development of inertial products. The French company Saifeng believes that the high precision hemispheric resonant gyroscope has creatively changed the inherent game rules of existing inertial products and has great potential to replace mechanical gyroscopes, optical gyroscopes and even atomic gyroscopes. This paper will elaborate the working principle and essential attributes of hemispheric resonant gyroscope, as well as its application status, value and advantages in high value-added products. At the same time, it will analyze its next technological development trend for reference and discussion in the industry.
