For the correct behavior of the Accuware Indoor Navigation engine, the compass of the device must be calibrated. If the compass is not calibrated it can happen that your location heads toward a wrong direction.
The accuracy of digital compass headings can be affected by magnetic or other environmental interference, including interference caused by:
- casings used to protect the smartphone/tablet.
- electronic devices.
- electromagnetic fields.
This is why the compass may need to be calibrated from time to time. The simplest way to check if your compass is calibrated is to use the built-in maps application of your smartphone/tablet.
