Please note that since the Guardian has no GPS, its position given by your smartphone, whitle the Pet's it's given by its own GPS. There are four main reasons why a Findster Duo user may get GPS position errors:
1. Using Findster Duo indoors
Usually this occurs because the Pet is trying to send its position while indoors. Findster Duo uses GPS technology, and due to this technology’s limitations the system is meant to be used outdoors (as is the case with any other tracking system that uses GPS). Positional errors will occur if the system is used indoors – or you might not be able to acquire a signal at all.
2. GPS data outdated
Instead, keeping GPS data updated will allow you to acquire signal faster and in a more accurate way.
3. Standard GPS error
This issue is unconnected to Findster Duo. It's related to the GPS satellites that are constantly in orbit around the planet broadcasting data. If their signal gets blocked due to tall buildings, atmosphere events or because you're underground, the GPS won't work. As you see, this depends very much on the surrounding environment and weather conditions.
4. Wrong Pet position
Although this information might be wrong, it's not an error. In the Home screen of the Findster Duo App, the distance from the Pet might be inaccurate because it refers to the Pet's last position acquired by the Findster Duo App. In the map, the pin will have the color you assigned to the Pet if its position is recent or will get grey if it's not recent.
Example: if you're using Findster Duo 5 miles from home, when you arrive home you'll get the information on your Home screen that your Pet module is still 5 miles away.
