一、概况现代海战要求每艘舰船必须能连续测定本身相对位置和近程位置。在海战情况下确保舰船,尤其是舰队的安全是至关紧要的,为此,必须获得精密的导航数据。目前,水面舰船采用的导航设备有惯导、雷达、无线电以及卫星导航等,但这些设备各有优缺点,而环形激光陀螺导航仪则以它精度高、可靠性好、结构简单紧凑、成本低、维修方便等优点倍受重视。就以可靠性为例,美国罗克韦尔国际公司(Rockwel 1 InternationalCorp)下属的航海系统分公司近年来研制了第一台预生产型激光陀螺导航仪,该导航仪主要部件平均无故障时间
First, an overview of modern naval requirements of each ship must be able to continuously determine their relative position and short-range position. In the case of naval warfare it is crucial to ensure the safety of ships, especially the fleet, and sophisticated navigational data must be obtained for this purpose. At present, navigational equipment adopted by surface ships includes inertial navigation, radar, radio and satellite navigation, etc. However, these devices each have their own advantages and disadvantages. However, the ring laser gyro navigator has the advantages of high precision, good reliability, simple and compact structure, Low, easy maintenance and other advantages of much attention. To reliability, for example, the Rockwell 1 InternationalCorp affiliated navigation system branch in recent years developed the first pre-production laser gyroscope navigation, the main components of the navigator mean time between failure
