The watch is primarily a GPS device for when the wearer is outdoors. For outdoor location working on GPS (Global Positioning Satellite), this means it gets its position when the watch is outdoors and can access a satellite. When you are looking at the location map on our App you will see a location box and, on the top right hand side of this box, it indicates what the watch is working off, either GPS or LBS, to give you its current location.
GPS indicates satellite positioning and its accuracy is 3 meters to 30 meters. When the watch is indoors and GPS is displayed on the App, up you can sometimes get shadowing which can make the GPS location display anywhere from 10 meters to 100+ meters from its actual location.
LBS (Local Base Station) can be displayed when the watch is indoors and this indicates cellular positioning which is usually accurate from 100 meters to 1000+ meters depending on the distance away from your nearest mobile phone base station that the watch is registered to.
In general GPS devices are designed for outdoor use, therefore they are not as accurate when used indoors. Please note that when locating a watch indoor the location can show as close as the house next door, or a lot further away depending on the LBS unit it is connected to. It is important to look at the location box to see if the watch is using GPS or LBS for location as LBS is not as reliable.
