The invention discloses a multi-moment ship position interpolation method based on automatic ship identification system data, which comprises the following steps of: selecting two ship positions in the automatic ship identification system data; calculating the distance between the two points; calculating the average navigational speed of two points; calculating the navigation distance of the interpolation time; calculating the arc length from the interpolation point to the equator; and longitude and latitude coordinates of the interpolation point are calculated. According to the invention, interpolation of the ship position specified time point of the ship automatic identification system can be realized, and a plurality of time points can be interpolated at the same time.
本发明公开了一种基于船舶自动识别系统数据的多时刻船位插值方法,其包括以下步骤:在船舶自动识别系统数据中,选定两点船位;计算两点间距离;计算两点平均航速;计算插值时间的航行距离;计算该插值点到赤道的弧长;计算出插值点的经纬度坐标。本发明能够实现船舶自动识别系统船位指定时刻点的插值,并能够同时插值多个时刻点。
