GEGO tracker relies on a strong connection with the GPS satellites in space to obtain an accurate location. If a tracker is inside a building, or in a trunk of a vehicle, it will typically fail to get any GPS signal. In some cases, however, the tracker won't completely lose its GPS signal, but the signal will be weakened. For example, a tracker in a vehicle that's under a tree may have a hard time fully picking up an accurate location. In these situations, you may experience what is known as GPS Drift. With a strong signal, GPS positions are typically accurate within 15-20 feet, but if there are obstructions that are causing a weak signal, the position can be off by as much as 200 feet.  If your tracker is fully obstructed, you will have no updated positions on your map and you will likely see this error message on your account: "Tracker doesn't have GPS signal. You may need to reposition."   Please Note: If your device is inside a building or parking garage, the above message is normal. As soon as your device leaves the location, it will regain GPS signal and normal tracking will resume.
