Consequently , computational models of all subsystems are constructed , such as the strapdown inertial navigation system ( sins ) , the control loop applied in self - control period , the guidance system by applying the technology of television ( tv ) guidance and the guidance law of proportion navigation , the autopilot by applying the technology of overload control in terminal control period , and so on 建立导弹各个子系统的计算模型，主要有捷联惯性导航系统、弹体、导弹自控段的控制稳定回路、采用电视制导和比例导引制导律的导引系统，以及采用过载控制的自动驾驶仪，然后在此基础上建立导弹各系统仿真模型。
