摘要
针对传统惯性航姿系统高纬度地区不能提供可靠航向参考的问题,将基于横坐标系的机械编排技术方案应用于航姿系统的姿态解算。针对高纬度应用需求,提出了航向精度指标的相对评价法,消除了纬度变化对于误差变化的影响。设计高纬度导航性能航行搭载测试试验方案,并完成了极地科考航行试验,结果表明采用横向机械编排的光纤航姿设备可作为高纬度地区的姿态参考系统。
The traditional attitude and heading reference system(AHRS)cannot provide reliable heading data in high-latitude areas.To address this problem,mechanization based on transverse coordinates for an AHRS is proposed for attitude and heading calculations.In terms of the requirements of accuracy evaluations in-high latitude areas,the relative specification evaluation method was employed to remove the adverse effect of latitude variance.Moreover,a scenario of a sailing trial for high-latitude navigation was designed,and a corresponding polar trial was carried out.The trial results showed that a fiber-optic gyro-compass using mechanization based on transverse coordinates could serve as a reliable AHRS in high-latitude areas.
