舰载机惯导动基座传递对准基准系统技术研究

Research on Reference System for Shipboard Aircraft Inertial Navigation System Transfer Alignment

根据舰载机惯导动基座高精度对准的需求,从系统顶层设计的角度,引入数字停机位空间坐标系概念,建立了舰载机惯导动基座传递对准的基准。在此基础上,分析了杆臂效应和船体挠曲变形对基准精度的影响,并给出了相应的处理模型和方法。舰载机可直接引入该基准坐标系下的导航信息进行对准,无须关注舰船性能参数和主导航安装位置等,有利于减少惯导动基座对准技术难度,提高对准效率。

From the perspective of conceptual design, the concept of digital space coordinate is introduced to meet the requirement of high precision alignment of shipboard aircraft inertial navigation system （INS）. On the basis of digital space coordinate, the effects of shanks-arms and ship flexure deformation on alignment precision are analyzed and hence the corresponding model and solution are provided. The shipboard can directly use navigation data of the digital space coordinate for alignment, regardless of ship performance parameters and the installation position of main navigation system, reducing the difficulty in alignment of shipboard aircraft inertial INS on moving base and improving the efficiency of alignment.
