Why the location is inaccurate?
The accuracy of the coordinates depends on a number of factors. We try to use all the available sources of coordinates on the device.
The location is formed on GPS, Wi-Fi (some models of watches, iOS and Android devices) and mobile networks.
Geolocation sources are used in the following order:
- GPS - the most accurate location, from 5 to 100 meters;
- Wi-Fi - the location of average accuracy, from 100 to 300 meters, in rare cases serious errors are possible;
- Mobile networks - an approximate accuracy, from 300 meters to 1.5 kilometers in the city and up to 10 kilometers out of the city.
At first the kid's device tries to form the location by GPS. However, the GPS signal may not be available indoors, and in some models of watches and smartphones GPS sensor is weak and because of some obstacles (for example, a transport roof or a pocket) GPS signal won't be available.
If GPS is not available but the kid's device has Wi-Fi, then the Wi-Fi networks are used to form the location. In this case, the accuracy will be a bit lower.
If neither GPS nor Wi-Fi are found, mobile networks (LBS) are used to form the location. The accuracy of the location is rather low.
In the parent app you can find how the coordinates are detected. If you see GPS, then the location of the kid is exact, Wi-Fi is rather accurate, but errors are possible, LBS (mobile networks) - the location is approximate.
When location is determined by mobile network, a point on the map could not move for a long time, and also notifications of entering and exiting from places may not be sent.
