【摘要】 惯性导航系统的空中对准一直是一个艰巨、复杂的环节。针对空投鱼雷内测记录系统中采用的捷联惯性导航系统提出了一种快速、简单、实用的捷联惯导初始对准方法。介绍了利用磁场值测量载体航向角的原理及ＨＭＲ３０００数字罗盘组件，并将其成功应用于空投鱼雷内测记录系统，解决了空中对准问题。最后给出了实验结果。更多还原

【Abstract】 The in-flight alignment of SINS has always been a difficult and complicated link to accomplish.According to the SINS applied in the aircraft torpedo inside-measurement system,a fast,simple and practical alignment technique is introduced. The principle of azimuth measurement based on magnetic value is described, and a new product HMR 3000 digital compass module is also introduced,which is applied successfully to the aircraft torpedo inside-measurement system,thus achieves the in-flight alignment. Finally the results of experiment are also showed.更多还原
