| 摘 要： | 陀螺寻北仪的算法改进采用基于二位置寻北算法.用转位对消常值漂移,并忽略惯性器件随机漂移误差项.将陀螺和加速度计的机械误差、物理量误差、标度因数及量化误差等测量值输入补偿模块,进行二位置寻北解算和转角误差补偿.实验表明本方法增强了寻北精度.

| Abstract: | Two-position seeking north algorithm is used to improve on algorithm of gyro north seeker. The basic method is to eliminate the constant drift by position transformation, ignore the random drift of inertial unit. Tested values of mechanical error, physical error, graduation factor and quantizing error were input into compensation module, then made the two-position seeking north computing and error compensation of rotate angle. Test result shows that the new algorithm improved the precision of gyro north seeker. |
