激光陀螺捷联惯导垂向通道测量研究

在参考国外相关垂向通道测量方法的基础上，提出了垂向速度和升沉位移的测量方法。分析了舰船在海平面上的运动特性，设计了关于高度通道的三阶阻尼网络。假设航行在海平面上舰船的高度为零，对阻尼网络引入外部零高度进行阻尼，得到舰船运动的垂向速度，对速度进行高通滤波，积分高通滤波后的高频速度，得到舰船的垂向位移。在此基础上，利用杆臂效应原理，设计了基于双轴摇摆台的升沉测量检测方法，对激光陀螺捷联惯导做了检测实验，结果表明此设计方法已达到国外相关技术先进水平。

Laser Gyro SINS Vertical Channel Measurement

Based on foreign correlated vertical channels measurement method, a new measurement method on vertical velocity and heave is designed in this paper. The motion characteristic of ship on sea is analyzed. And three order damping net about altitude channel is designed. On the assumption that the altitude of the sea level is zero, an external zero altitude is directed into damping net. And the vertical velocity of ship motion is obtained. Through filtering vertical velocity and integral high frequency velocity, the ship heave is got. On this basis, using the principle of the level arm effect, a heave measurement test method is proposed. The test results show that this measurement method achieves advanced level of foreign correlative technology.
