This is a big leap forward from previous “vertical” indoor navigation applications that are custom built for specific B2B use cases and application areas, represent closed environments, and have associated high costs. The human body, using miniaturised inertial sensors (accelerometers and gyroscopes). SatNavs are now almost standard equipment for the motorist and GNSS plays a large role in applications as diverse as agriculture and surveying. These allow indoor navigation to be achieved by measuring the accelerations and rotations of the object to be tracked, i.e. On the use of navigation services by non-expert users.

If a suspect carries a mobile phone that a law enforcement agency has a fix on, or they are being closely followed by a covert officer, they too may be tracked.

But tapping into the The navigation demo was set up to “know” that it was inside the LVH Hotel; in a commercial application, an app would get this initial geographic information from the phone's GPS receiver. This also allows accurately estimating movement patterns of individuals and crowds. Add in ambient light detectors, air sensors, temperature sensors, microphones, and cameras, and it all means that app developers can make mobile devices do amazing things. Pressure sensors help determine altitude.
