Öz Global Positioning System (GPS) is a satellite network that sends some encoded data regularly and it makes possible finding any location on the Earth by employing measurements between satellites and receiver [1]. The satellites of GPS spread radio signals consistently. Receivers of GPS take these signals. This project presents a system that processes data, which are taken from GPS with an electronic circuit, and shows on a map the real-time location via a web site [4]. In addition to this process, the system supplies geofencing opportunity. For the geofencing operation, a point is marked as a center and a geofencing limit is determined. When the distance from the point is larger than the geofencing limit, an alarm will be occured. The system, proposed within this project, supplies a real-time geolocation tracking application with some tolerance. This fault tolerance depends on some factors like air condition or number of linked GPS satellites. Several experiments were achieved to prove the effectiveness of the proposed system that results are encouraging and motivate authors for further studies
