摘　　要：针对某机载光电平台高精度长航时测姿问题,设计一种载机主惯导与光电平台子惯导之间的动基座传递对准方案。方案采用主子惯导间的速度+方位角匹配模式,利用反馈校正方式来实现对MEMS惯导的长时间高精度的对准。文中给出了对准算法的数学模型、数据同步的方法等,并经仿真表明:在1800s时间内,飞机自由飞行条件下,MEMS子惯导的姿态、航向的对准误差均可控制在0.1°左右。说明本方案可行,具有较好的工程应用价值。In order to meet the requirements of high precision and long time attitude measurements of opto-electronic platform in aircraft,a transfer alignment on moving base scheme for the master and slaver inertial navigation system was designed.The Scheme was based on the velocity matching plus heading matching mode.And the longtime transfer alignment Kalman filter based on feedback correction mode was designed.Meanwhile an effective data synchronization method was proposed.The simulation results show preliminarily that the misalignment vector precision is at the advantage of 0.1°under the free flight maneuver condition in 1800 seconds.Those prove that this system is effective and practical.
