GPS signal problem on Polar watch

You use a polar watch for many years and you have always been very satisfied with it. A true assistant in your daily activity, Polar has comfortably established itself as an indispensable brand in the “smart watch” market.

Unfortunately, despite the reliability of these devices, it can sometimes happen that they do not work properly.

And among the problems the most frequent are those linked to GPS. Indeed, you notice that your Polar watch has trouble finding its way around, and the indications are approximate, or even incorrect.

Not very practical when you rely on it to lead you. In this article, we want to provide you with an answer in order to solve this GPS signal problem.

Here are solutions to set up for fix GPS errors on your Polar watch.

But before embarking on the search for a solution to the problem, it is important to understand how a GPS works on a Polar watch.

How a GPS works on a Polar watch

Your GPS, otherwise called " Global Positioning System", Determine your exact position by a triangulation system. This means that different satellites around you send information, and wait for a response back from your watch, in order to determine your position, depending on the orientation of the signal response, and also on the response time.

It is therefore a data exchange between satellites around you, and your Polar watch.

As you move, the travel times of the different signals therefore vary. This allows your watch to determine that you are on the move.

In the best of all possible worlds, this is the mode of operation when the signal is strong, and of good quality. Now here are the different factors that can influence your GPS signal and cause problems with your Polar watch.

Different causes of GPS signal problem on a Polar watch

In order to solve this problem, it is first necessary to analyze precisely the origin of the problem. This will make it possible to have a diagnosis of the situation, and thus implement corrective measures.

Weather conditions that influence the GPS signal

Before you cry foul and think that the weather is influencing the GPS signal, it is important to educate yourself on the subject. No, the weather does not influence the GPS signal.

At least, not in 95% of cases, and that in a relatively negligible way. The only impact the weather could have would be torrential rain, and more.

Snow could also influence this, but it is often not the cause of a weak or imprecise GPS signal.

Are you in a place clear enough for the GPS signal

First thing to worry about when the GPS is imprecise, watch your surroundings. As explained above, this GPS signal is sent by satellites, and can therefore be disturbed by a particular landscape:

  • You are in the forest and the vegetation is very dense
  • You are in town, surrounded by tall buildings
  • You are in a very hilly environment, potentially surrounded by hills or mountains

As you can see, your environment can influence the GPS signal, when simply, solid elements get between you and the satellites in the sky.

To get the best signal possible, and as far as possible, it is recommended to run in an open area, in order to have maximum precision.

Solutions to fix GPS signal problems on a Polar watch

If, however, you are used to running in an open area, or suddenly the signal no longer works even though it has always been accurate, then there may be a problem.

Here are the different tips or manipulations to put in place to help you find a stronger and more precise GPS signal.

Disable battery saver

If you do not need it, you should deactivate the battery saver because it greatly affects the quality of the GPS signal. For that, it's very simple :

  • On the home screen, slide the menu down
  • Open them Parameters
  • Press on " System« 
  • Here you will find the option to deactivate the battery saver. Confirm the operation and then exit the option menu. Wait a few seconds to see if the GPS signal improves

Is the GPS recording of your watch activated?

GPS recording during one of your activities is optional. So, if it is not activated, it is normal for the GPS not to work.

To take advantage of it, here's how:

M400 / M430 :

  • On your Polar device, go to the Settings
  • Then open the tab »Sports profiles« 
  • Then choose the sport practiced, then activate GPS recording

Grit X / Ignite / Vantage M / Vantage V 

  • You can activate GPS in the sport profile settings as explained above, or use the application or the web service

Warning : If you do this on the app or the web service, be sure to synchronize the settings, otherwise they will not be active on your Polar device.

Use your Polar watch with the dial facing up

A small detail which may seem trivial but which can have an impact. Try to keep your watch the right way up on your wrist to optimize its signal.

It is sometimes with the small details that we solve the most restrictive problems!

Make sure the A-GPS tool is up to date

Polar uses a GPS coordinate synchronization tool to maintain a high degree of accuracy for its watches and bracelets. So if your device is synchronized and up to date, it has additional information to optimize the signal.

To update it, connect your device to your computer or smartphone, then simply sync it!

You can check the date of the last update of this A-GPS file, on your watch, in this way:

  • Settings   
  • General Settings  
  • About your product or watch
  • Date exp. A-GPS

If the date of the file is today, then the file is up to date! Otherwise, update it with the above manipulation.

Reset your Polar watch

Sometimes, a little "reset" of your device would allow it to start again on a better basis. It will not affect your personal data. If you want to do that, follow this article:
