Do you own an Amazfit smartwatch and notice that it positions itself more and more slowly and with errors? This is a fairly common problem related to a key element, A-GPS data: if it is out of date your smartwatch will not position correctly, especially at the beginning. And he has a simple solution.
Like any other device, a smartwatch’s GPS sensor measures the time it takes for the signal to travel back and forth to the satellite. calculate the intersection of all signals in order to offer precise positioning for sports practices. Although there is another element that comes into play that is also vitally important.
A-GPS data is the key to better positioning
Calculating the position at the cost of measuring the intersection created with the signal from all visible satellites makes it possible to obtain coordinates whose precision will vary depending on the quality of the smartwatch, due to the fact that it does not have no obstacles above and how fast it is moving the clock. A-GPS allows you to speed up localization and improve the calculation of coordinates using data that combines the GPS signal and the mobile network.
To position yourself as quickly as possible, your Amazfit watch downloads A-GPS data from your usual situation which include known references so that the watch takes this into account when connecting with the satellites. These references are of vital importance for outdoor sports, because, if the A-GPS is outdated, you will notice that the margin of error increases in your runs and it will be difficult for you to position the Amazfit before starting training.
If your Amazfit takes time to connect to GPS and the margin of error increases with each turn, the A-GPS data is outdated
Watches need to frequently update their A-GPS data. And th is is done from the Zepp application on your Android: if you notice that your Amazfit is not positioned well, it is best to look at this:
- Open the Zepp app on your Android and make sure the watch is properly connected.
- Go to the bottom tab “Profile”.
- Click on your Amazfit watch, the one that is connected (in case you have several registered).
- Scroll down to “A-GPS Ephemeris”, click there and click “Update”.
- After the process, you will have updated A-GPS data.
Generally, your Amazfit watch should notify you when A-GPS is out of date (in the watch settings, under “Training”, the A-GPS expiration warning option appears), but, ‘after my own experience, You will not always receive this notice.. Therefore, to avoid erroneous training and waiting before starting each sporting practice, the ideal is to check the status of the A-GPS with a certain frequency. Now you know how it’s done.
