The accuracy of GPS tracking coordinates depends on many factors. At the very beginning, let us get to know the three methods of tracking.
GPS or Beidou is the most accurate location, from 5 to 100 meters. The Global Positioning System (GPS) and Beidou GPS Positioning System are both satellite-based radionavigation systems that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
Wi-Fi positioning: the location of average accuracy, from 100 to 300 meters. The working theory of WiFi positioning is not to use WiFi to connect to the internet but to use the location data of Wi-Fi hotspots. Once the device detects there are WIFI hotspots around it, but there should be at least 3 WIFI hotspots around, the nearest WIFI hotspot location data will be saved and sent back to our server to analyze, then back to Google map, where finally the WIFI location can be shown up in the APP.
LBS tracking uses the base station of mobile networks and has an approximate accuracy of 300 meters to 1.5 kilometers in the city and up to 10 kilometers out of the city.
After knowing that, now you need to check what kind of watch you ordered and its parameters.
If you ordered cheap phone watches that do not have a GPS module at all, then you can use WIFI tracking or maybe only LBS tracking. If you want better GPS tracking, you can return the watch and order the advanced models.
When the devices have GPS and WIFI available, the watches will normally use GPS tracking when you are outside a building, because during this time the GPS signal is strong. However, if you are inside the building, normally the watch will use Wi-Fi.
They have a few tips for you if you want GPS tracking with better accuracy.
1. You had to wear the watch out of the building, not put it on your hand, to get that touch-base signal.
2. You can try to set the GPS data upload interval at the minimum. By default, the app allows you to set 10 for every 10 minutes of GPS updating.
3. You can push the GPS icon on the map to request the latest GPS location update.
