陀螺传感器是飞行控制,惯性导航和火控系统的基本部件。由于惯性导航系统在军民用飞机和导弹系统上的应用正在不断扩大,所以对陀螺仪的需求量也在不断增加。目前,陀螺仪的市场从航空,航天工业扩展到陆军、海军的设备领域。这样就要求发展体积小、重量轻、结构简单、工作可靠,又容易启动和维护的陀螺仪。这就要求改进现有陀螺性能,探索新原理的陀螺,以满足不同精度要求和不同用途的需要。表1列出制导和导航对陀螺仪性能的主要要求。表2列出各种陀螺仪的主要优缺点。
Gyro sensors are the basic components of flight control, inertial navigation and fire control systems. Demand for gyroscopes is also on the rise due to the growing use of inertial navigation systems in military, civilian aircraft and missile systems. Currently, the gyroscope market has expanded from the aerospace and aerospace industries to Army and Navy equipment. This requires the development of small, light weight, simple structure, reliable, easy to start and maintain the gyroscope. This requires improving the existing gyro performance, to explore new principles of gyro, to meet different accuracy requirements and different needs. Table 1 lists the main requirements of guidance and navigation for gyroscope performance. Table 2 lists the main advantages and disadvantages of various gyroscopes.
