摘要
对用激光原理进行绝对速度测量和由它实现自主导航的概念进行了探讨。利用3个陀螺仪和3个激光测速计按直角坐标方式配置,即可组成基于绝对速度测量计的捷联式惯性测量组合。这种方法的优点是简化计算和有利于提高精度。
The concept of absolute velocity measurement and autonomous navigation system based on laser theory are discussed. 3 gyroscopes and 3 laser velocity measuring instruments are collocated according to right - angle coordinate system so as to compose a strapdown inertial measurement unit. This method is simple and has high precision.
