In recent years, many companies want to keep track of personnel, sources and working machines due to various reasons. This is sometimes achieved for security purposes and sometimes for coordination and performance purposes. The purpose and requirements are the main factors that determine the shape of tracking. Such developed systems for this purpose have different technologies according to their requirements. The real-time tracking can be determined with high precision in open areas with the global positioning system (GPS). However, previous research and developments for indoor tracking have mostly focused on infrared, wireless LAN and ultrasonic. In this study, the infrastructure of the system was designed by using RFID technology. The use of open source Geographical Information Systems (GIS) as a substructure also provided spatial display and analysis possibilities for this study. The open source t database is also integrated into this system. The tracking algorithm is completely unique and original and is encoded in the Java programming language. In the algorithm, the accuracy of locating the proximity, direction and whether the RFID reader is on the right and left of the last point received is increased. The methodology used was tested in an underground salt mine and proved to study successfully.
