Performance of radar assisted satellite based automated train transit system

In this article, we present the performance of an automated train transit system using radars and a Geo stationary satellite. The Radars placed along the railway tracks update the accurate speed and position of the train to the central base station which controls the trains over a wide geographic region. The central base station directs the train by communicating via a Geo stationary satellite. The proposed system model does not require visible signaling for trains. It also eliminates the possibility of a collision between two trains. Further, the use of multiple radars ensures that system doesn't fail, even if any of the radar fails. Our performance study shows that the effect of rain on the satellite link requires at least a 5dB additional signal to noise ratio (SNR) at the receiver to maintain the same bit error rate (BER).
