Expected accuracy of location detection.
Location accuracy is low. The most suitable mode for determining the current city/area. This mode is characterized by low power consumption. In this mode, the device can either rely solely on networks (Wi-Fi, 3GPP, IP), or use GNSS -receiver in low power mode (with geolocation caching for a long time).
Location accuracy provided by a standard GNSS receiver. The most suitable mode for displaying the current location on a map. If a GNSS receiver is installed on the device and the satellites are in the field of view, then satellite data is used to determine the location. Otherwise Alternate location sources are used.
Location accuracy provided by a standard GNSS receiver and possibly improved with additional tools. The most suitable mode for route guidance. Similar to Medium mode, but the GNSS receiver can be set to a higher accuracy mode, or can be used to refine the location additional sensors. May consume a lot of power (device in this mode is usually connected to a power source).
