摘要
高精度的惯性导航系统是提高舰船综合作战性能的基础。为了提高惯性导航系统的精度,采用单轴旋转惯性测量组件的方法,研制了激光陀螺单轴旋转惯性导航系统。介绍了系统的硬件组成,主要包括系统基本结构,惯性器件的主要技术参数和导航计算机的组成。描述了系统的多位置初始对准方式和温度补偿方案。对该系统进行了长时间静态导航实验和跑车实验,实验结果表明:四次长时间静态导航实验峰值定位误差5d优于1nm,10d优于2nm;两次跑车实验峰值定位误差77h优于1.4nm、15d优于2.5nm。
High precision inertial navigation system is the base of integrated performance in ships. In order to improve the performance of the inertial navigation system, a method to rotate the inertial measurement unit is developed. The hardware of the system is introduced, which mainly includes the basic configuration, the performance of ring laser gyroscope and accelerometer, and the diagram of navigation computer. The scheme of the alignment and the temperature compensation are described. The static tests and outdoor vehicle tests are performed. The results show that the peak position errors of the four times static navigation tests for 10-day cycle are less than 1 n mile within 5 days, and 2 n mile within 10 days. The peak position errors of the outdoor vehicle tests are less than 1.4 n mile within 77 h, and 2.5 n mile within 15 days.
