光纤陀螺惯导在航海领域的发展与应用

针对航海导航领域对惯性技术发展的新需求,从系统精度、旋转调制技术、陀螺性能等方面出发,梳理了国外航海惯导技术的发展脉络。由此总结出了航海惯导三点新的发展需求,包括定位精度、研制成本、使用维护性,同时给出了满足当前发展需求的一个研究方向,那就是采用超高精度的光纤陀螺研制航海惯导。最后从陀螺精度极限、温控、全阻尼等几个方面进行简要的可行性论证,并给出了部分验证试验结果,试验结果表明光纤陀螺惯导在航海领域具有广阔的发展前景。

The Development and Application of Fibre Optic Gyroscope INS in Navigation Domain

Based on the new requirement of marine navigation for inertial technology development, the development of overseas navigation technology is reviewed, focusing on system precision, rotating modulation and gyro performance. And the demand of marine inertial navigation development is discussed in terms of positioning precision, manufacturing cost and maintenance. Then one of the development directions that can meet the current development demand is pointed out, which is INS based on FOG of ultrahigh precision. At last, the feasibility discussion of the limit of FOG precision, temperature control and absolute damping is presented. Part of experiment result is offered and shows the vast development prospect of FOG-based INS.
