Design and implementation of a GPS based DCS network time synchronization board

In today´s world of computer based control systems, there are so many applications which require precise timing. In order to maintain a precise time in those time needing systems, the time synchronization idea has been developed. Today there are many Commercial Products doing this job. In this paper we are trying to build a simple and Low Cost GPS Based Computer Network Time Synchronization Board, using NTP Protocol. This small leap can help effectively toward a giant leap of making an industrial Time Synchronization Product capable of synchronizing time of a real Distributed Control Systems(DCS).
