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 ephemeris data to refine the collar's GPS tracking. 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, 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 an "Indoor GPS", "Outdoor GPS", or "Hybrid GPS" connection. The collar makes this determination based on the strength of the GPS signals it is receiving. When your collar is detecting that it is indoors, it will not issue any corrections. We are continuously working to improve this algorithm to ensure the most accurate GPS readings possible.
There is also a GPS LED 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 LEDs, please see the article "How do I interpret the LEDs?"
In the event of a firmware update, the battery dying, or the collar spending an extended period of time indoors, you may be prompted to take the collar outside to allow it to re-calibrate to GPS signals. 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.
