摘　　要：舰载武器捷联惯导系统(SINS)初始对准的精度以及时间决定着武器系统打击的准确性以及快速性。由于舰船航行环境复杂多变,舰载武器捷联惯导系统利用舰船主惯导(MINS)提供的高精度导航信息进行牵引对准可以提高其对准的精度和速度,保证作战任务的顺利完成。对舰载武器捷联惯导系统利用主惯导提供的导航信息进行牵引对准,并对其性能进行半物理仿真,然后利用牵引对准后捷联惯导系统的姿态跟踪主惯导姿态的精度来评价对准的性能。仿真结果表明,静态条件下,牵引传递稳定后,牵引传递造成的航向基准传递误差小于1.8′(0.03°),姿态基准传递误差小于10.8″(0.003°);动态条件下,牵引传递稳定后,牵引传递造成的航向基准传递误差小于2.4′(0.04°),姿态基准传递误差小于10.8″(0.003°)。为后续各个作战平台牵引对准模型的建立提供一定的参考。The accuracy and time of initial alignment of shipborne weapon strapdown inertial navigation system(SINS)determine the accuracy and speed of weapon system attack.Because the navigation environment of ship is complex and changeable,the strapdown inertial navigation system(SINS)of shipborne weapon uses the high-precision navigation information provided by the ship’s main inertial navigation system(MINS)for traction alignment,which can improve the accuracy and speed of alignment and ensure the smooth completion of combat tasks.In this paper,the performance of shipborne weapon strapdown inertial navigation system using the position and velocity information provided by the main inertial navigation system is analyzed by semi physical simulation,and the alignment performance is evaluated by using the attitude tracking accuracy and time of the main inertial navigation system after the traction alignment.Through the analysis,it is concluded that under static conditions,after the traction transfer alignment is stable,the heading reference transfer error caused by traction transfer is less than 1.8′(0.03°),and the attitude reference transfer error is less than 10.8″(0.003°).Under the dynamiccondition,when the traction transfer is stable,the heading reference transfer error caused by traction transfer is less than 2.4′(0.04°),and the attitude reference transfer error is less than 10.8″(0.003°).This paper provides a certain reference for the establishment of the traction alignment model of each subsequent combat platform.
