本文首先分析了国内外普遍采用的摆式罗盘在海洋浮标上进行瞬时采样时的动态工作误差,从而论证了大、中型浮标选用捷联式系统的必要性。其次研究了捷联式罗盘的基本要素,从而阐明了这种新型仪表应用于海洋浮标必须解决的问题和适用条件,第三介绍了根据国家海洋浮标网第一个大型浮标工程要求制定的捷联智能系统方案和针对性精化措施、FQCX—1系统构成、工作原理、计算机数学模型与程序框图;最后记述FQCX—1在10m浮标上的安装校正和应用效果,说明该仪器已达到或接近80年代国际先进水平,满足了这项“七·五”计划国家重大科技攻关工程对它的预定要求。
This paper firstly analyzes the dynamic working errors when the pendulum compass is widely used at home and abroad for instantaneous sampling on marine buoys, thus demonstrating the necessity of using strapdown systems for large and medium buoys. Secondly, the basic elements of the strapdown compass are studied, and the problems and applicable conditions that must be solved when applying this new instrument to marine buoys are clarified. Thirdly, the strapdown based on the requirements of the first large buoy project of the National Marine Buoy Network FQCX-1 system structure, working principle, computer mathematical model and program block diagram; finally described FQCX-1 10m buoy installation and calibration and application results, indicating that the instrument has reached or approached 80 The advanced international standards of the age have met its scheduled requirements for major national scientific and technological projects under the “Seventh Five-Year Plan”.
