Recently, with the development of information and communication technology, efforts have been made to integrate BIM and augmented reality technology into maintenance. The augmented reality is worth to be introduced because it has advantages of visualization and interaction. In order to introduce augmented reality into the maintenance that most of the work takes place in the indoor environment, it is essential to track the exact position of the user. this study suggests a location tracking method for indoor environment using iBeacon technology and the PSO(Particle Swarm Optimization) algorithm for optimal location. The parameters required for the proposed PSO location confirmation algorithm are presented through various experiments and the accuracy is verified by applying it to the actual indoor space. The result shows that the smaller the measurement result space, the smaller the measurement error and the smaller the standard deviation. The iBeacon-based location tracking technology can be applied sufficiently to provide the necessary information at the location where the user is located, rather than the task of checking the accurate location of the maintenance work.
