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 bubble, press the Antenna icon on the left hand side of the bubble to see 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.
With regards to GPS working inside of buildings, GPS signals are carried through waves at a frequency that does not move easily through solid objects. A GPS device relies on a series of satellites in order to determine where it is physically located. The signals sent from these satellites do not penetrate all kinds of barriers with ease. When you use a GPS inside a building, a wide variety of physical barriers and potential interference sources make it difficult for the device to pinpoint your location accurately.
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 bubble to see if the watch is using GPS or LBS for location as LBS is not as reliable.
When the location is reporting location using LBS, you can check the last reported GPS in your app. In your app Press the Track icon to show the location history of the watch. Set a “Start date” and “End date”. The ‘show activity’ should be “on” and the LBS & Wifi positioning should be turned “off”. The last GPS position will then show.
