 +The application is able to use the navigation satellite systems (GNSS) chip available in most devices and locate your real-time location on the map. Depending of your device capabilities, your location can be computed using the GPS, the GLONASS or the Galileo systems, or a mix of them.
  
-Most devices now have a GPS chip which is used to compute this location. GPS provides precise location while not using any cellular network. However, it must have a clear access to the sky, meaning that it cannot be used indoor.+The GNSS provides an usually precise location, and does not require cellular network coverage.

 If the "''**Positioning status**''" option is checked, an information box {{:icon_08.png?nolink}} lets you know how much satellites have been found yet. In this case, ''**4/8sats**'' means that ''**8**'' satellites have been found in the sky, and ''**4**'' are being used to compute the current location.
