随着工业电子及其相关技术的飞跃发展,惯性技术及其系统也获得了很快发展。如果说十年前,在航空、航天领域以挠性陀螺取代液浮陀螺为标志的平台式惯性导航系统(INS)应用最广,而今天国外以激光陀螺等无高速回转体的器件为主构成的捷联式INS已处于扩大使用阶段。进入80年代末期,基于振动理论的半球谐振子陀螺又引起了各国的关注,并被认为比激光陀螺更具有竞争优势。 With the rapid development of industrial electronics and related technologies, inertial technologies and their systems have also been developed rapidly. If ten years ago, in the field of aeronautics and astronautics, the top-mounted inertial navigation system (INS) with flexible top instead of floating top was the most widely used. Today, foreign countries mainly focus on components such as laser gyro without high-speed rotating body Of the strapdown INS has been in an extended phase of use. Into the late 1980s, based on the vibration theory of hemispherical resonator gyro has drawn the attention of all countries, and is considered more competitive than the laser gyro.
