Abstract
This thesis is study about the Light Buoy Synchronous Lights design and implementation using the GPS receiver module.

The Light Buoy is a facility which shows a safe route of the sea. The most important function of the Light Buoy is the synchronous flicker showing the route certainly.

However, the synchronous flicker form using mainly up to now makes difficult to the correct implementation because it occurs a time lag between the Light Buoy with the passage of time. Presently, the most effective way to use the Light Buoy flicker is using the crystal oscillator which has marginal error of ~ second.

The ways of wireless data are used to solve these defects but these ways have several problems. First of all the frequency allotment is needed to transmit the radio and the available range is limited which is between 20 km and 50 km. So due to system errors of the ground, serious problems will be ocurred.

In this thesis I implemented the synchronous flicker of the Light Buoy with good GPS which is safer and more trustful than any other systems. As a result, I could conformed that however time may passes the Light Buoy which uses GPS with very high precision Reference clock always becomes correct synchronous flicker.
