惯性制导(inertial guidance) 利用陀螺仪和加速度表组成的惯性测量装置测量导弹或运载火箭的运动参数以修正其飞行路线偏差的一种制导方式。惯性测量装置测出导弹或运载火箭运动参数的变化,计算机根据实时测得的数据、发射前输入的初始条件和重力影响等数据,算出导弹或运载火箭的实际飞行速度、航向、姿态和坐标,并将这些数据与制导程序要求的预定值进行比较,根据偏差大小 Inertial guidance (inertial guidance) An inertial measurement device consisting of a gyroscope and an accelerometer is used to measure the movement parameters of missiles or launch vehicles to correct for the guidance of flight path deviations. The inertial measurement device detects the change of the missile or rocket motion parameters. The computer calculates the actual flight speed, course, attitude and coordinates of the missile or launch vehicle based on the data measured in real time, the initial conditions input before launch and the gravity impact, And these data and the guidance program requirements for comparison, according to the size of the deviation
