The Halo System uses world-class global GPS and GNSS technology that is on par with the navigation systems used in autonomous cars and drones. The System harnesses 6 satellite networks. It works autonomously and is accurate within a few feet. It even gets more accurate as you use it more often!

You can check the status of your GPS signal, both in your app and on the collar. In the app, you can tap on your dog's Pet Card to view their status and other information. The Pet Card will indicate if the collar is receiving a "Low GPS", "High GPS", or "Medium GPS" connection. The collar makes this determination based on the strength of the GPS signals it is receiving when either outside or indoors.

• When your collar is detecting that it is indoors, it will not issue any corrections. It should always be in low GPS mode.

There is also a GPS light on the front of the Halo Collar, underneath the power button, that will indicate the kind of GPS connection your Halo Collar is experiencing. For more information on how to interpret the collar's lights, please see the article What do the lights on the collar mean?

In the event of a firmware update, the battery dying, or the collar spending an extended period of time indoors, you may want to reinitialize the GPS by following the steps on How to Optimize GPS Accuracy This should only require a few minutes. 

• The Halo Collar performs best while in motion so grabbing the collar by the buckle on the strap and positioning it so that the speaker is facing upwards, by slightly bouncing the collar, you will help the collar become more accurate and gather satellite data. This is all taking place while your dog is wearing the collar as well!

We are continuously working to improve the algorithm to ensure the most accurate GPS readings possible. To learn more about how often your collar sends location information to your phone, check out the article “Why is there a difference between my dog’s location and what I see in the App?”
