GPS & A-GPS The watch supports the Global Position System (GPS) tracking. When you do outdoor exercises like running, the GPS will automatically start working and notify you when the positioning is successful, and quit tracking once you stop exercises. The open field outdoor is the best place for the GPS tracking; whereas when you are in a dense crowd, raising your arm up can beter help GPS to the positioning. It is recommended to start your workout only when the GPS starts working. The watch has an Assisted GPS (A-GPS) feature which can accelerate GPS positioning via the data directly from the GPS satellites.
Make sure your watch is connected with the phone via the Bluetooth, the data can be automatically synchronized from app to your watch, and the A-GPS data automatically updated as well. In case the data has not been synchronized for seven consecutive days, the A-GPS data will expire. If so, the positioning information will need to be re-acquired. You can go to the page of outdoor exercises on your watch to update the positioning information. 05
