| 摘 要： | 惯性导航系统是核潜艇水下导航主要手段之一，然而惯导的定位误差是累积发散的，必须利用外位置信息进行校正。甚低频导航可实现水下定位，因此可利用其位置信息完成惯导水下输出校正，主要对基于差分甚低频位置信息实现惯导输出校正进行仿真分析，结果证明该方法的有效性。

| Abstract: | Inertia Navigation System (INS) is one of important method to underwater navigation for submarine. But its position error grows without bound with time,it must correctes position error. VLF navigation system can provides position underwater, so it can carries out output revising. This paper simulates output revising based on position provided by differential VLF, and the result shows the method is effective. |
