Abstract

The Kinematic CPS is well known to provide a quite good accuracy of positioning within an level. Although kinematic CPS assures high precision measurement on the basis of an appreciable distance between a reference station and an observational point. it has measurable distance restriction within 20 km from a reference station on land Therefore, it is necessary to make out a simple and low-cost method to obtain accurate positioning information without distance restriction In this paper, the velocity integration method to get the precise velocity information of a ship is explained The experimental results of Zig- zag maneuver and Williamson tum as the ship's maneuvering test, and other experimental results of ship's movement during leaving and entering the port with low speed were shown From the experimental results, ship's course, speed and position are compared with those obtained by kinematic-CPS, velocity integration method and dead reckoning position using Gyro-compass and Doppler-log.
