Abstract

An asset tracking system using GPS, SMS, and a mapping software was designed and implemented. Arduino, an open-source single-board microcontroller, was used as the processing unit of the tracking device because of its easy-to-use hardware and software. SMS was used as the transmission layer for the system. The device logs real-time GPS data and transmits these data to a computer via SMS. The mapping software running on a remote computer unit receives GPS data thru Globe Tattoo and uses Google Maps"' API to plot coordinate points on an online map. The tracking system was aimed to have minimal cost with the use of Arduino and Google Maps. The performance of the system was assessed and evaluated by examining the accuracy and precision of GPS readings, transmission rate of GSM, power consumption, and reliability. Tests done showed that the GPS readings of the tracking device were precise up to 1.96 meters and 2.19 meters for latitude and longitude readings, respectively. The accuracy latitude and longitude readings were found to be 0.56 meters and 0.09 meters accurate compared to Locosys GT-3l GPS Reader, respectively. The distance perception test also showed an average percent error of 2.32%. The fastest possible transmission rate of the tracking device was found to be one GPS data sent every 10 seconds. The battery life could last for at least 10 hours depending on the transmission rate of the tracking device. The tracking system was able to monitor the movement of a van from SM Pala-Pala, Dasmarinas, Cavite to Crossing Terminal, Calamba, Laguna. The tracking lasted for about two hours and the software obtained 237 text messages containing GPS data.
