为减小系统编排的复杂程度,减小计算量,根据小型战术导弹射程近、飞行时间短的特点,建立了简化的惯导基本方程及相应的系统编排模型。在传统三子样旋转矢量算法的基础上,采用改进型三子样旋转矢量变量更新算法建立了捷联惯导仿真平台,并通过仿真验证了惯导方程简化的合理性和算法的正确性。

According to the characteristics of near range and short time of the small tactical missile, raise a SINS model simplified, establish the scheduling system model specifically, in order to decrease the complexity of model scheduling. By building algorithm simulation platform, improve the method of three sample rotation vector variables updating on the basis of researching on traditional three sample rotation vector optimized algorithm. The simulation results show that adopting such the SINS model and algorithms can meet needs of navigation precision of small tactical missile.
