Assisted GPS (A-GPS) is a system allowing global positioning system (GPS) receivers to obtain information from network resources to assist in satellite location. An A-GPS system is especially useful when the receiver is in a location where it is difficult for the satellite signals to penetrate.
AGPS will help your watch find your precise position quickly and improve accuracy.The A-GPS data updates once a day. The latest A-GPS data is automatically updated each time you sync it with Amazfit APP.
If watch hasn’t sync with your Amazfit APP for 7 days, Agps data will expire.
The positioning speed may be affected when AGPS expires and watch will remind you to update when you start an activity.
