Abstract A ship guidance system is helpful for the detection of location and movement of ships in the river or near at the port. In this research, we have developed a ship guidance system using grid mapping method to help to locate and control the movement of ships properly. The system is designed to generate a grid map of different color which represents different depth. By comparing the accepted information from the server with the current water level and needed depth for ship, we can get a specific map for every ship. As the ship moves forward, the map also gets update due to the change of the ship's location on the grid. This creates a moving real time grid map, which could be used to navigate the vassal. The location of ship is calculated using delay of signal (which travels at the speed of light) and simple rectangle theories. The depth of channel is stored as a 2 dimensional matrix in the database. This information is sent to the ship through Omni directional antenna using Frequency Shift Keying (FSK) modulation technique. The ship crosslinks this information with the information of its depth and angle to generate a real time map.
