摘　　要：现有潜射战术导弹射击训练中,对于导弹弹道的监控只有出水之后的空中弹道,而水中段尚无有效的监测手段。而在训练打靶过程中,水中段是最薄弱环节,导弹最易出现故障且故障原因难以确定,水弹道测量将为这些问题的解决提供依据。论文将MEMS惯性传感器应用于潜射战术导弹水弹道测量中,以捷联惯导姿态更新中最恶劣的工作环境——锥运动作为仿真环境,分析四阶龙格库塔法和毕卡算法的优劣,并以梯形公式计算毕卡算法中的角增量,仿真得出的结论有很好的工程实用价值。Aerial trajectory can be measured merely in the launch trainings of submarine‐launched missiles ,and under‐water trajectory is not yet measured at present .Underwater trajectory is the most vulnerable in the whole trajectory and the breakdown reason is difficult to confirm .Measure of the underwater trajectory provides the possibility of breakdown analy‐sis .The paper applies MEMS inertial sensors in underwater trajectory measurement ,considering conical motion as attitude updating simulation environment .Trapezoid formula is used to calculate angle increment of Pirkanmaa algorithm ,and analyse advantages and disadvantages of fourth order Ronge‐Kutta method and Pirkanmaa algorithm .Ultimately conclusion by simu‐lation is commendable to engineering application .
