前言捷联式惯性制导系统就是不采用平台,直接把陀螺和加速度表安装在弹体上来敏感导弹的运动,用数字计算机来进行坐标转换,求出导弹相对惯性空间的速度和位置,从而实现制导和控制。捷联式系统具有成本低、寿命长、可靠性高的优点,已受到苏、美各国的普遍重视。由于新型敏感元件(挠性陀螺、激光陀螺、挠性加速度表等)和大、中规模集成电路的高速数字计算机的出现,使得捷联式系统得以在工程上应用。近几年来,在航空、航天活动中,捷联式系统正受到越来越多的重视。
Introduction Strapdown inertial guidance system is not using a platform, the gyro and accelerometer directly mounted on the missile body to sensitive missile movement, with a digital computer for coordinate conversion, to find the missile relative inertial space velocity and position, in order to achieve guidance And control. The strap-down system has the advantages of low cost, long service life and high reliability, and has been widely valued by countries in the Soviet Union and the United States. Due to the emergence of new sensitive components (such as flexible gyroscopes, laser gyroscopes, flexible accelerometers, etc.) and high-speed digital computers in large and medium-scale integrated circuits, the strapdown system has been applied in engineering. In recent years, in aviation and space activities, the strapdown system is receiving more and more attention.
