Indoor Positioning System (IPS) for Smartphone Users

Indoor Positioning System (IPS) for Smartphone Users


Technology Summary

  • This technology is an indoor localization platform, which enables any service provider to make indoor location information without installing any dedicated positioning H/W, for indoor Location Based Services (LBS).
  • In this technology, by using our smartphone application and surveying devices, both reference location and raw data of several sources, such as Wi-Fi, BLE, magnetic field, barometric pressure, and images, can be gathered dynamically.
  • The platform analyzes gathered data and generates a location database (DB) in a location server. Accurate positions of users can be estimated with the DB and the hybrid positioning system, also the DB can be updated using the data from users.
