Modularized fiber-optic gyroscope inertial navigation system

The utility model relates to the field of aviation inertial navigation, in particular to a modularized fiber-optic gyroscope inertial navigation system. Comprising an electronic hardware part mounted at the front part of a case and a fiber-optic gyroscope inertial measurement unit part mounted at the rear part of the case, and the fiber-optic gyroscope inertial measurement unit is in signal crosslinking with the system electronic hardware through a sealing connection cable assembly. According to the utility model, a modularized design concept is adopted, and each module adopts a standard interface, so that the universality is good. According to different application requirements, rapid development of products meeting the requirements can be achieved by cutting and combining all the modules, and meanwhile the technical risk caused by redevelopment is greatly reduced. 本实用新型涉及航空惯性导航领域，具体涉及一种模块化光纤陀螺惯性导航系统。包括安装于机箱前部的电子硬件部分和后部的光纤陀螺惯性测量单元部分；所述光纤陀螺惯性测量单元通过密封连接电缆组件与所述系统电子硬件实现信号交联。本实用新型采用模块化的设计理念，各模块采用标准接口，通用性好。根据不同应用需
