速率捷联控制系统主要是由与弹体捷联的速率积分陀螺仪,摆式加速度表以及微型计算机,伺服机构组成。这类系统在飞行中要完成稳定与制导的任务,首先需要求解弹体坐标系的初始值。对于地一地导弹或运载火箭来说,就是必须首先解算出发射瞬时,弹体坐标系 Velocity strapdown control system is mainly composed of velocity integrated gyroscope, pendulum accelerometer and micro-computer and servo mechanism which are connected with missile body. Such systems in flight to complete the task of stability and guidance, first of all need to solve the initial value of the projectile coordinate system. For ground-to-ground missiles or launch vehicles, the launch instantaneous, projectile coordinate system must first be solved
