摘要
引言 伴随着现代导弹技术的诞生,出现了“制导”的概念。为了引导导弹自动飞向预定的目标,需要有能反映飞行体运动状态参数的敏感器获取导弹飞行路线的信息,还要有手段获取目标的信息,然后对测量信息综合处理得出将导弹引导到目标的控制和导引信号,通过执行机构校正飞行弹道以完成飞行使命,这就是制导。
After a brief historical review,strapdown inertial guidance is introduced and the grand trend of development of strapdown inertial guidance technology is described. The trend has become especially clear with the latest achievements of optical gyros. Finally,a mathematical tool for describing the attitude movement of rigid body, the quaternions, and the concept of combined navigation are explained.
