If your pet is shown in the wrong location while in the augmented reality view, this deviation from reality is most likely quite normal and caused by the current limitations of GPS technology.
The augmented reality feature uses both the GPS location of your smartphone and that of your tracker.
While these locations are most likely quite accurate, it's important to keep in mind that no GPS system is 100% accurate. According to the U.S. SPS Performance Standard, GPS signals provide an accuracy of 7.8m (25 ft) at a 95% confidence level.
Therefore this can cause some deviations when the GPS tracker is in the immediate surroundings of your smartphone. The possibility of GPS inaccuracy in both devices and the combination thereof can lead to a distance representation that is larger than the actual distance.
