GPS based real time Emergency Aid System with analysis of latency in satellite communication

Around 4.2 million people commute by vehicles every day. The breakdowns and accidents augment the traffic woes, adding to the misery of these commuters. In order to obtain control over these situations, immediate assistance should be extended. This paper proposes an `Emergency Aid System (EAS) and Remote tracking of Vehicles´, which ensures prompt assistance in case of unfortunate events like accidents and breakdowns. This is possible by sending an SMS to the nearest service aid station via 2G technology. The system implements latest technology of GSM modem with a sufficient baud rate and a GPS antenna that continuously tracks the coordinates of the vehicle. The complete analysis of the system, along with the study of time taken (latency) in exchanging the data between the GPS antenna and Satellite is studied and the results are presented.
