Abstract: The main problem we face when developing a radio-based indoor positioning system is the environment's heterogeneity. Not only does this heterogeneity have an impact on the radio waves' propagation, but the environment itself evolves, on several time scales, making it difficult to predict the waves' characteristics.
Owl Positioning System (OwlPS) is an indoor positioning system based on the IEEE 802.11 (Wi-Fi) standard, developed at the University of Franche-Comté, France. It features a self-calibration (or autocalibration) mechanism, allowing the avoidance of a tedious manual calibration of the system, but above all the ability to take into account the radio environment variations in real time. This talk will be articulated into three main parts:

  • An overview of indoor positioning basics, and especially of the radio-based indoor positioning techniques.
  • A detailed presentation of the OwlPS system.
  • The self-calibration mechanism implemented in OwlPS.
