甲板变形测量技术研究

当舰上的主导航系统与载机子惯导之间进行传递对准时,船体的变形会引起对准误差。想消除船体变形的影响从理论上讲,挠曲变形可以通过卡尔曼滤波进行估计,但在实际上很难建立足够精确的模型。通过船体变形的测量与校正技术,在大型载舰存在复杂动态变化的情况下,可采用分布式姿态基准,在载舰上的不同部位安装有限套惯性测量单元（IMU）,与舰上主导航系统构建成一个惯导网络,为载机子惯导的传递对准提供更丰富、更准确的载舰状态信息,从而大大提高传递对准的精度的研究。

Research on Deformation Measurement of Warships

The deformation of the ship would cause alignment error when transfer alignment was carried out between the master navigation system and the slave navigation system of warships. Theoretically, the flexure can be estimated by Kalman filter but it is hard to establish accurate model. Distributed attitude reference system can be used to measure complicated dynamic flexure of large-sized ships. Limited Inertial Measurement Units(IMU)are installed at different position of the warship, these units and the master ...
