摘　　要：根据舰艇中一般配备两套或多套互为备份惯导系统的情况,提出了双惯导系统的阻尼新方法。在借鉴传统水平阻尼网络的基础上,针对双惯导系统的特性设计了新的阻尼网络,并分析了其误差源与双惯导阻尼网络的关系,对双惯导系统的导航参数进行线性组合输出。通过仿真分析,比较两套阻尼系统的仿真结果,可以看出双惯导水平阻尼能够显著降低外速度误差的影响,抑制经度误差。Based on the status quo of two or more INS be equipped in naval ships, a new method of DINS （Double Inertial Navigation System） was presented. In light of the character of the DINS, a damped network was based on the traditional design of damping equalizers for the vertical errors, and the relation between a various of errors and the new level damped system was analyzed, and the Navigation information of DINS was combined. The simulation results show that the level damp of DINS can reduce the influence of the external velocity error, and restrain the error of longitude effectively.
