The Tagg trackers use advanced GPS technology to provide fast, highly accurate, location information across the broadest range of conditions.
The Global Positioning System (GPS) we use is a U.S.-owned utility that interacts with GPS receivers to provide three-dimensional position and time. The GPS website states that, in the worst case, location accuracy is within 7.8 meters (25 feet) with 95% confidence. The accuracy can be affected by other factors, such as solar flares, but it can also be improved with various augmentation systems and advanced technology, such as that used by our Tagg trackers.
As well, whenever your tracker is not close enough to the base station to "hear" its radio signal, our system will still be able to communicate with the tracker. For more information, see our GPS Coverage Map.
