摘要:

为实现水下潜航器高精度长航时航行,基于SINS/DVL组合导航的误差抑制和校正技术是关键。对于DVL数据失效情况,介绍了不同的替代方法。比较了SINS/DVL组合数据融合常见滤波算法;从长航时导航误差抑制和校正角度,叙述了阻尼算法、地形辅助校正、重力匹配辅助定位、长基线系统辅助定位和重力扰动补偿等方法。可为水下潜航器SINS/DVL组合长航时导航误差抑制提供参考。

Abstract:

In order to achieve the high accuracy and long endurance of underwater vehicle, it is essential to apply the technique of error suppression and correction based on strap-down inertial navigation system/ Doppler velocity log (SINS/DVL) integrated navigation. This paper introduces different alternative methods when Doppler data fails, and discusses SINS/DVL data fusion filter techniques. It illustrates the damping algorithm, terrain assisted correction, gravity matching assisted positioning, long baseline system assisted positioning and gravity disturbance compensation to further suppress or correct the navigation errors accumulated over time. This paper provides reference for underwater autonomous navigation with high accuracy and long voyage time.

Key words: strap-down inertial navigation system/Doppler velocity log(SINS/DVL) integrated navigation, DVL data failure, data fusion, long endurance, error suppression
