The location tracking system is the combination of the Global Positioning System (GPS) and the Global System Mobile communication (GSM) technologies via the microcontroller. It is used to detect the GPS location of vehicles or any objects which are attached to a tracking device. The proposed system made good use of popular technology that combines a smartphone with an Arduino UNO. GPS is a satellite-based navigation technology that provides accurate location and information. The GSM module is used to transmit and receive an update from the object location to a database. Data from the numerous satellites are received by GPS receiver in the National Marine Electronics Association (NMEA) protocol form. The system SMS contains latitude and longitude of the location of the object. The NMEA code consists of a combination of information. Arduino is linked to the GPS and the GSM module in the serial connection. The GPS receiver sends data to Arduino. Then, Arduino instructs the GSM module to send the location data to the GSM enable device in a short message form. Thus, by using the tracking system, it is easy to calculate and get the estimate location and time for the vehicle to reach a given destination.
