文章针对舰载导弹捷联惯导系统,提出了一种原位标定方案。此方案在不需要将惯导系统从导弹上拆下来,且无需借助转台等测试设备的条件下,利用捷联基准提供的速度和姿态信息,采用系统级标定法对惯性器件误差进行了标定。计算机仿真结果表明,文中给出的方法可以有效地完成导弹捷联惯导系统原位标定,且标定精度较高,具有较强的实际意义。
In this paper, an in-situ calibration scheme is proposed for shipborne missile SINS. This scheme calibrates the inertial device error by the system-level calibration without using the inertial navigation system from the missile and without using the test equipment such as turntable, etc., using the speed and attitude information provided by the strapdown reference. Computer simulation results show that the method given in this paper can effectively accomplish the in-situ calibration of missile SINS, and the calibration accuracy is high, which has strong practical significance.
