Selection of technology for building an indoor localization and tracking system

Over the past few years, the role of such positioning systems as Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) in the big cities is falling rapidly. The reason for this is the increasing density, height and area of the buildings. The walls of the buildings are among the key problems in the performance of these positioning systems. In addition, the above systems are failing with their tasks in such large-scale buildings as museums, exhibition and shopping centers etc. In this regard, in recent years, a new global challenge in the field of indoor positioning appeared - the localization and subsequent navigation of mobile objects (pedestrians, vehicles and robots) in enclosed areas, as well as the environment in which satellite navigation systems for some reasons are not efficient.
