Abstract: The project design and implementation of a GPS (Global Positioning System) tracking system with Arduino Uno, GSM SIM900A module,GPS L89 Module were meant to send Location information in form real-time or short alerts SMSs via a pre-registered mobile number. The Arduino is the master which commands the GSM module to send SMS messages, and also communicates with GPS device for getting geographical coordinates. When started, the GPS is constantly reporting where you are-this information is sent as a Google Maps link through the GSM. The system may send regular updates, or return answers to GPS commands requesting the location details of individual units-solving their communication reliability issues plus optimizing for power and signal quality. It can be used to personal safety and asset tracking for a very low price.
