Alignment Method for SINS-Tachometer Integration Based on Reverse Navigation Algorithm
转速计因其价格低廉,且能够测得自主式水下航行器(AUV)在高速航行过程中相对周围海水的轴向速度,从而成为捷联惯导系统(SINS)在行进对准过程中的辅助设备。基于此,文中提出一种SINS与转速计组合的方法。利用转速计的量测数据对惯性传感器采集的信息加以修正,并利用逆向解算的思想,对系统获取的数据信息进行正逆向交替处理。通过增加对准阶段采样数据的处理次数,进而提高系统的对准精度和性能。仿真结果表明,在捷联惯导与转速计组合方式下,既可实现快速对准,同时…查看全部>>
Tachometer is cheap, and it can measure autonomous underwater vehicle′s relative axial velocity to surrounding water during high speed navigation, so it becomes an auxiliary device for alignment of strap-down inertial navigation system(SINS). In this paper, a method for integrating SINS and tachometer is proposed. The data from tachometer are used to correct the infor-mation collected by inertial sensors, and the information obtained from the system is proce…查看全部>>
