Tracking systems were developed to keep track of shipped goods. Passive systems were deployed for this purpose in olden days. However for applications requiring Real time location information, Active systems are required to transmit the location of the vehicle in Real time. This paper proposes an integrated tracking system design with GPS and GSM to incorporate location information and surveillance using SMS to determine the exact location of an object , person or other asset to which it is attached . Using GSM modem this information can be transmitted to a remote user. This system contains a single board system equipped with GPS and GSM modems along with PIC Processor. A software is developed to read, store, process and analyze the incoming SMS message. This system can be a valuable tool for providing real time control and monitoring.
