| 摘 要： | 在传统的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方法并分析了各种误差与这种阻尼网络的关系。通过仿真分析,比较2套阻尼系统的误差结果,可以看出双惯导外水平阻尼能够显著降低外速度误差的影响,减少阻尼时间,抑制经度误差。

| Abstract: | In light of the character of the DINS(Double Inertial Navigation System),a new damped network was presented on the base of the traditional design of damping equalizers for the vertical errors,and analyze the relation between a various of errors and the new level damped system.In this paper,the simulation results show that the level damp of DINS can reduce the influence of the external velocity error,decrease damping time,and restrain the error of longitude effectively. |

| Keywords: | DINS level damped system external velocity |
