针对水下潜器在极区工作时，其常用惯性导航系统机械编排存在精度下降、无北向基准等问题，设计了适用于水下潜器极区工作的横坐标系捷联惯性导航系统机械编排方案。在构建了横坐标系参考框架的基础上，推导出各导航参数在横坐标系统和常规坐标系统之间的转换关系，建立了横坐标系捷联惯导系统的机械编排，并在此基础上分析其误差传播特性。通过误差分析，确定了横坐标系捷联惯导系统中存在的周期性振荡，并提出了适用于横坐标系捷联惯导系统的阻尼技术，有效抑制了周期性振荡。最后，通过仿真试验验证了该系统在极区工作的可行性和阻尼技术有效性。

Common mechanizations for submarine inertial navigation system (INS)involve problems of ac-curacy depressing,lack of north benchmark and so on.Aiming at this problem,a transversal strapdown INS mechanization is designed here,which is applicable to polar regions.The navigation reference framework of the transversal coordinate system is constructed.The navigation parameter transformations from the transversal co-ordinate system to the local-level coordinate system are deduced.Moreover,mechanization of transversal strap-down INS is established,and then an error analysis for the transversal strapdown INS is performed.Through error analysis,periodic oscillating errors existing in that mechanization are determined,and damping technology applicable to that mechanization is proposed to reduce those errors effeciently.Finally simulation test is per-formed to validate the feasibility of this system in polar regions,as well as the performance of the damping tech-nology.
