Study on Precise Prediction of Ship's Position Using EKF

Abstract

It is important to predict other ship's position, speed and direction for own ship from a point of view of collision avoidance on the sea. Nowadays, RADAR or ARPA System is generally used to predict these factors of other ships. However, the predictions have been estimated mainly based on a simple linear prediction technique. In this paper, authors propose a new method to predict more precisely the ship's behavior based on the observed data through RADAR or ARPA using an Extended Kalman Filter technique.
