Indoor positioning systems are becoming popular nowadays. Indeed, there is plenty of opportunities for real-time user navigation in GPS-denied environments. An interesting use cases are as follows: Fig. 1. Indoor navigation use cases There are several options for hardware (see It-Jim blog post). We have developed the positioning algorithm based on cheap Bluetooth beacons and built-in IMU sensors on a mobile device.
In our swarming world, it is quite hard to imagine someone having no mobile phone in the pockets of their jeans, dress, or suit. Even the inveterate skeptic has to accept the fact that smartphones entered our life and have become its inalienable part, the part of us.
The development of indoor navigation services and algorithms is becoming a popular trend in the IT industry in recent years. Some of the modern buildings, like airports, shopping malls, and warehouses have grown enough (Fig.1) to feel a need for their own navigation tools for customers. Closed environment conditions exclude the usage of common satellite-based navigation systems like GPS or GLONASS, so nowadays some alternative information sources of user localization appear at the scene.
