Abstract :
In most cases indoor local positioning algorithms are not effective enough. RSS-based methods are very sensitive to variations in physical environment dependent on relative positions of furniture, doors, human bodies, etc. The results of ToF-based ranging in closed areas always include additional NLOS-component. A method of combination of both RSS and ToF approaches is described. Results of conducted indoor experiments confirmed that the accuracy of position calculation significantly increased.
