INTERPOLATION OF SHIP DYNAMIC DATA ON AIS MESSAGE CONSIDERING THE CHARACTERISTICS OF SHIP MOTION

Abstract

In this research, an interpolating method for AIS datat of ship is proposed considering feature of ship motion. The proposed method includes a linear interpolation and dynamic one. The advantages of this proposal is to interpolate the ship’s velocity and ship position by motion feature, meanwhile the ship heading, and course over ground is interpolated by linear interpolation. To verify the proposed method, one real example is conducted to ship sailing in Haiphong area.
