【摘要】 为适应现代战争的需要,特别是现代战争的快速反应,惯导系统需要在很短的时间内完成粗对准后,在行进过程依靠简单的外部信息完成精确的寻北工作,这样能够显著提高系统的灵活性和机动性.介绍了高精度捷联惯导采用速度匹配对准方案实现行进中高精度方位对准,不需要对载体提出特别机动要求,在10m in内完成方位对准,方位对准精度优于3.3′secL.试验证明,该行进中对准方案能够实现高精度的水平及方位对准,具有良好的实际工程应用效果,达到了理论对准精度水平.更多还原

【Abstract】 In order to adapt to the expeditious modern war,INS is required to accomplish coarse alignment shortly and then find the azimuth of carrier on moving base with the assistant of outside simple message.It is introduced that the high precision SINS achieves high precision north-finding with velocity match alignment.In the course of alignment,the carrier isn’t required any special maneuver.The heading alignment accuracy is better than 3.3′secL in ten minutes.It is proved that this scheme has good effect in practice and can achieve alignment accuracy in theory.更多还原
