| 摘 要： | 圆锥误差是影响捷联惯导系统姿态算法精度的原理性误差,其对三轴激光捷联惯导系统精度的影响显著.对三轴机抖激光陀螺捷联惯导系统,除了弹体运动可能引入圆锥运动外,三轴机抖激光陀螺产生的机械抖动也会在惯导系统中引入圆锥运动.文中分析了两种圆锥运动在三轴激光捷联惯导系统中产生的机理,并给出了圆锥误差补偿算法在不同试验条件下的应用效果.

| Abstract: | Conning error is a principle error of strapdown attitude algorithm, which degrades the attitude precision greatly. To three-axis laser SINS, besides the conning motion introduced by carrier, there are conning motion introduced by dithering of three-axis laser gyro. The cause of two kinds of conning motion is analyzed, and the application result of conning error compensation algorithm in different test environment is described. |
