摘要
面对水下装备无人化/智能化的发展趋势,系统分析国内外知名惯性导航系统生产公司的产品,梳理水下装备的核心设备——惯性导航系统的发展趋势.基于工具检索国内外知名惯性导航系统公司的公开文献、专利以及产品手册等开源信息,提炼关键信息以及参数进行对比分析.目前,光纤陀螺惯性导航系统在国内已成为实现水下装备高精度定位的核心产品,基于谐振陀螺的惯性导航系统尚处于研发阶段.国际市场上,基于激光陀螺的惯性导航产品正逐渐被基于谐振陀螺和光纤陀螺的惯性产品替代.从法国赛峰和Exail这两家顶尖公司的产品指标看,谐振陀螺高精度惯性产品相比光纤陀螺高精度惯性产品而言,无论在体积还是在质量上都有较大优势,后续可能完全替代光纤陀螺系统成为市场主流.
Abstract
Underwater equipment are advancing towards unmanned/intelligent capabilities.Hence,products from renowned domestic and international manufacturers of Inertial Navigation Systems(INSs)are systematically examined to clarify the development trend of such systems.Utilising tools,key information and parameters from publicly available sources such as public documents,patents,and product manuals from prominent domestic and foreign INSs manufacturers are comparatively analyzed.Currently,domestically manufactured fiber-optic gyro INSs have been deployed and established as a foundation for underwater equipment to achieve high-precision positioning.Meanwhile,resonant gyro INSs remain in the research and development phase.In the global market,laser gyro-based inertial navigation products are progressively being replaced by those based on resonant and fiber-optic gyro products.Evaluation of product metrics from leading French firms,Safran and Exail,reveals that resonant gyro-based high-precision inertial products offer considerable advantages in terms of both size and quality over fiber-optic gyro-based high-precision inertial products.Thus,they can potentially displace the latter entirely and emerge as the mainstream product in the market.
