The Halo System uses leading-edge global GPS and GNSS technology that is on par with the navigation systems used in autonomous cars and drones. The System works autonomously and is typically accurate within 3-7 ft. However, as with all GPS receivers, there is a performance fluctuation from location to location, which is due to the nature of the technology itself.
We have developed unique and highly-advanced algorithms to calculate signal accuracy, motion, speed, and even the direction your dog is facing. The combination of GPS technology, hardware, software, and firmware all work together seamlessly to create a clear picture of your dog's behavior, their location in relation to fence boundaries, and to provide instant, consistent Prevention and Encouragement Feedback to keep them safe anytime, anywhere.
Over time, your dog's Halo Collar will even collect and aggregate data to refine the GPS coordinates of your fence. This means that with each use and with longer times connected, the data provides increasingly accurate readings to ensure that your dog has the coverage needed to keep them safe - regardless of weather or cloud cover.
While tree coverage may initially affect your GPS accuracy, our amazing engineers have developed the most advanced solutions available to recalibrate your dog's location information using the technologies described above.
You can also check the status of your GPS signal 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. If you are receiving a weak GPS signal, you'll see an icon on your screen that says, "Weak GPS" directly on the card. For example, if you're indoors with your dog while he or she is wearing the Halo Collar, you'll see this icon appear to let you know that your GPS may be less accurate while your dog is inside. There is also a "GPS LED" light on the front of the Halo Collar underneath the power button that will indicate whether you're currently experiencing a weakened GPS connection.
In the event of a firmware update, the battery dying, or the collar spending an extended period of time indoors, you should take the collar outside to allow it to re-acclimate to the GPS signal. Keep it outside until the blue GPS light starts blinking - this can take up to 20 minutes, but will often only require a few minutes.
