精确制导火箭弹传递对准研究

摘要

Before the Guided Rocket is launched, its missile-borne Slave Inertial Navigation System (SINS) should be aligned at first. According to the characteristics of Guided Multiple Launch Rocket System (GMLRS), using Position and Azimuth Determining System served as Master Inertial Navigation System (MINS), the velocity plus attitude matching transfer alignment scheme is applicated to determine the initial attitudes of SINS. Test procedure in three-axis turntable is also presented, and test results show the scheme can accomplish the task accurately, fleetly and the needed maneuver is simple.%以常规火箭弹制导化改造过程中弹载捷联惯导的初始对准为背景,研究了利用发射车车载高精度定位定向系统作为主惯导,对火箭弹捷联惯导进行传递对准的速度加姿态匹配方案,介绍了在三轴转台上进行实验验证的方法、过程和结果.实验结果表明,该方案对准精度高、对准时间短、对准机动要求简单,可以有效完成制导火箭弹捷联惯导的初始对准.
