舰船惯性导航系统的双重信息导航工作方式

Dual -Information Navigation Mode for SINS

—舰船惯性导航系统通过不同的机械编排实现不同的导航工作方式，它们各有不同的误差方程和特点，以适应不同的条件。传统的设计方法在具体条件下只实现一种工作方式，保持一种方式的导航信息。本文论述了舰船惯性导航系统中首次应用的双重信息导航工作方式，以这种方式工作的惯性导航系统可在一套物理系统中同时生成，并保持水平阻尼与罗经回路两种工作方式的导航信息。文中分析了该工作方式的原理和特点，并对试验结果和应用情况做了有限说明。

SINS(Ship's Inertial Navigation System)can be operated in differ-ent navigation modes by means of different mechanization. In different modes SLNS has different error equations and different particularities. Only one kind of navigation mode can be performed and informations of one kind of navigation mode can be maintained in SINS with traditional design method.The dual information navigation mode which was first designed and operated in SINS has been described in this paper. The navigation in-formations of two basic modes-horizontal damping and gyrocompassing loop can be produced and maintained in one physical system with the dual information navigation mode.The theory and particularities have been analyzed as well as some trial results and uses have been given.
