Abstract :
With the emergence of satellite based positioning techniques, outdoor environments have been covered well by GNSS positioning capabilities. Recent focus has shifted towards the indoor environment where the satellite signal propagates poorly. We consider the potential to locate objects and people indoors as a substantial building block for the human development. If we are looking towards seamless positioning in all environments, the indoor environment poses the crux. Several indoor positioning applications are waiting for a satisfactory technical solution in industrial automation, product tracking, stock-keeping, pedestrian navigation in hospitals, homes for the impaired, burning buildings, museums, for the purpose of ambient assisted living, for location based systems and further applications.
