摘要
分析了延长惯导系统重调时间的几种关键技术,提出了一种自主式组合导航系统,在水下即可完成对惯导的校正,对导航陀螺漂移进行补偿。同时还提出了对导航陀螺漂移补偿的优化组合算法。理论分析及计算机仿真结果均表明,应用该组合导航系统可提高潜艇的导航定位精度和隐蔽性。
Several technologies for extending the reset cycle of the inertial navigation system （INS） are analyzed, and an independent integrated navigation system is presented. The gyro drift is compensated and INS is corrected under water. Finally, an optimal combined algorithm for compensating the gyro drift is given. The theoretical analysis and experimental results indicate that the integrated navigation system can improve the precision of the navigation and the invisibility of the submarine.
