Ever seen either of these symbols or something like them appeared on your phone or device?
The chances are, the answer to that question is yes.
These are the symbols used by Android and Apples devices for location services. If they appear on your phone, they normally indicate that your device is actively calculating your current location.
This can be done in a number of ways but most commonly uses GPS (global positioning system) to pinpoint the location of your device, and therefore you.
GPS uses satellites to provide location information to the receiver in your device. It does not require data or phone reception as it operates separately from these systems, however devices now will often use a combination of GPS, internet and telephone systems to provide geolocation information.
