| 摘 要： | 惯导对准过程中陀螺仪漂移率的测量是一个重要的工程实际问题，经典的闭环测量在测量精度和快速性等方面存在缺点。研究了开环测漂的方案，利用递推的最小二乘法获得了陀螺漂移的计算公式。实验证明，开环测漂方案既能满足精度要求，又能保证快速性，切合工程实际的需要。 |

| Abstract: | Existing closed-loop methods for measuring gyro drift can not meet the precision and speed requirements needed for initial alignment of INS (inertial navigation system). We now propose an engineering open-loop method that can meet the precision and speed requirements needed for initial alignment of INS in China. For this open-loop method, we derived a number of equations that are needed in the process of computing gyro drift. Experimental results show preliminarily that our open-loop method for obtaining gyro drift can meet the precision and speed requirements needed for initial alignment of INS in China. |
| Keywords: | inertial navigation system (INS) gyro drift open-loop method |
