3. Introduction What is G.P.S ? The acronym for G.P.S is Global Positioning System. The acronym for G.P.S is Global Positioning System. G.P.S is a worldwide network radio navigation system. G.P.S is a worldwide network radio navigation system. G.P.S constitutes a constellation of minimum of 24 satellites. G.P.S constitutes a constellation of minimum of 24 satellites.

4. Indian Railways: World’s largest Railway network. World’s largest Railway network. Large means of public transport. Large means of public transport.Drawbacks: Lack of sufficient Safety. Lack of sufficient Safety. Still wide use of manual and traditional methods. Still wide use of manual and traditional methods. Creating loss both to the public as well as national property. Creating loss both to the public as well as national property.

5. How G.P.S is applicable to Indian Railways ? GPS will be used to get the details of the train such as the speed and exact position of the train. GPS will be used to get the details of the train such as the speed and exact position of the train. Navigation in three dimensions. Navigation in three dimensions. GPS will provide the means of the communication GPS will provide the means of the communication

6. Principle and working of the system : Childhood principle of checking whether a train is coming or not by hearing the vibrations from the track.
