The invention relates to the technical field of electric digital data processing, in particular to a ship track information display method, device and equipment and a medium. The method comprises: determining a speed mode of a ship; when the speed mode is a low-speed mode, counting an average value of east speed measured by the inertial navigation equipment and received per second and an average value of north speed measured by the inertial navigation equipment and received per second; the longitude position change value and the latitude position change value of the ship are determined regularly according to the average value of the east speed and the north speed counted within N seconds before the current moment, the track direction of the ship is determined, and the track direction is displayed; and when the speed mode of the ship is a normal navigation mode, the track direction of the ship is determined regularly according to the position information measured by the satellite navigation equipment, and the track direction is displayed. According to the embodiment of the invention, the track direction of the ship can be accurately determined on the basis of the east direction speed and the north direction speed measured by inertial navigation equipment under the condition that the ship sails at a low speed.
本发明涉及电数字数据处理技术领域,尤其涉及一种船舶航迹信息显示方法、装置、设备及介质。方法包括:确定船舶的速度模式;当速度模式为低速模式时,统计每秒接收到的惯性导航设备测量的东向速度的平均值、每秒接收到的惯性导航设备测量的北向速度的平均值,定时根据在当前时刻之前的N秒内统计出的东向速度和北向速度的平均值确定船舶的经度位置变化值和纬度位置变化值,确定船舶的航迹向,显示航迹向;当船舶的速度模式为正常航行模式时,定时根据卫星导航设备测量的位置信息确定船舶的航迹向,显示航迹向。本发明实施例可以在船舶低速航行的情况下,基于惯性导航设备测量的东向速度和北向速度,准确地确定船舶的航迹向。
