Yes; all Tractive GPS devices require a GPS signal in order to determine your pet's precise location. Read on to learn more about GPS.
How does GPS tracking work?
The Tractive GPS tracker uses GPS (Global Positioning System) to accurately determine its location. The tracker receives signals from GPS satellites with a built-in GPS antenna and infers the distance to the satellites from the signal's travel time.
The tracker can calculate its position when the distance to at least four satellites is established. The more GPS satellites it can detect, the greater the accuracy. You can track your pet in default or LIVE Tracking mode.
How accurate is GPS?
The Global Positioning System (GPS) is influenced by many environmental factors. Each location is uniquely calculated and has its own associated accuracy.
A location determination at location X with an accuracy of 5 meters means that the real location is within a 5 meter radius.
According to the U.S. GPS Performance Standard, GPS signals provide an accuracy of 7.8 m (25 ft) at a 95% confidence level when calculating the distance between satellite and receiver.

If the GPS connection is lost, you will see the last known position of your pet on the map. You might lose the GPS connection inside buildings. Normally, the GPS signal will be reestablished when the device is outside with a clear line of sight to the sky.

What happens if my tracker loses GPS signal?
Losing GPS signal from time to time is normal for any GPS device - including navigators and smartphones. In case the tracker cannot get a GPS signal, it will make use of several other technologies to try to locate your pet and update you via the app accordingly.
