Proposal of User Adaptive Modular Localization System for Ubiquitous Positioning

摘要

The paper deals with general concept of modular and portable localization system that utilizes existing radio network infrastructure. The modularity means multiple independent collections of algorithms and technologies that allow determining geographical position in various radio and geographical environments. The portability of the system is provided by implementation into small pocket-sized device. The environments are characterized mostly by the parameters of available radio systems such as Global System for Mobile Communications (GSM), Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard-based ones or Global Navigation Satellite Systems (GNSS). Suitable software and utilization of a portable device equipped with necessary hardware can turn the system into the provider of ubiquitous positioning service.
