摘要
针对航标抛设锚体入水点位选取依赖人工经验、抛设精度低问题,研究基于GPS的抛标定位方法。定义了船载GPS坐标异常值剔除指标,探讨了三种抛标船航行轨迹拟合方法,实现了根据轨迹拟合方程对抛标锚体入水点位的精确预测,结合算例验证了其有效性。
According to the issues of artificial selection of anchors＇ entry point and lowaccuracy mark setting,navigation mark location method based on GPS was studied.The elimination of abnormal ship-borne GPS coordinate was defined.Three trajectory fitting methods were investigatedto accurately predict the anchors＇ entry point via trajectory fitting equation.The effectiveness of the method was verified by numerical example.
