How Accurate Are GPS Trackers?

Global Positioning System (GPS) technology has become a big part of modern life, a useful process at the heart of any vehicle tracking system. 

Through a tracker’s connection to satellites in space, the device can determine a person or object’s location on Earth with astonishing precision. 

However, with technology as advanced as this, is there room for error? Can GPS trackers be wrong?

What do the Numbers say?

According to the Official U.S. Government website about GPS accuracy, GPS trackers are very accurate and can determine a location within 16 feet or 4.9 meters 95% of the time.

Its accuracy is critical as it is used by people all over the world for many purposes, such as tracking an asset’s location and gathering geographical data. Trackers can be installed on vehicles, cars, and trucks as well.

Even parcels from Amazon are tracked through GPS to ensure prompt arrival. In this case, the trackers are located on cargo freighters and cargo ships headed to the destination.

Meanwhile, the military also uses trackers on their submarines, tanks, planes, and trains. Military equipment often uses trackers with two GPS receivers instead of one for greater accuracy.

The most common use of GPS is in trackers found on mobile devices and cars to help drivers navigate.

Unfortunately, in rare instances, GPS trackers can fail too. They can give provide incorrect information despite the high accuracy rate.

How & Why do GPS Trackers Fail?

GPS trackers work by connecting to at least four satellites to get data and information, failing to connect to these satellites causes errors.

The signal can also be blocked by bridges, mountains, tunnels, concentrations of high concrete buildings, and so on. Anything that blocks the connection between the tracker and the satellite will cause interference, resulting in inaccuracy.

Even if there is interference along the way, If your tracker loses signal, it should continue to record your location until it regains connection. After a connection has been reestablished, your tracker will upload all the information stored when there was no mobile coverage.

Another factor that causes inaccuracy is if your tracker hasn’t been used in a while. The quick fix to this is to allow your tracker to send it’s signal again as it will automatically correct itself. This should take a minute.

While many things affect a GPS tracking device’s accuracy, most of these issues can be fixed easily. And as technology advances, your Solid GPS tracker will only get more accurate.

How do I Fix My GPS Tracker's Accuracy?

GPS trackers may fail sometimes, but there is no need to panic when that happens since it’s pretty easy to fix minor issues. There are several steps you can do to troubleshoot and fix the device and be back on track.

Check the app.
Apps fail, and they can sometimes give incorrect information. Before anything else, check the application you’re using and make sure it isn’t an issue with the app. If it seems to be the app, try to reset it and wait a few seconds. It might not even be the GPS tracker at all.

Make sure your tracker is in a good position.
In Solid GPS’ case, we recommend hiding your unit inside the boot, under your car seat or anywhere hidden inside your vehicle. Most of the time your unit should be able to get a good, clear signal.

Resetting your unit.
Sometimes turning your unit off for a minute and then turning it back on again is the best thing you can do to get your unit up and running again. We also recommend you do this if you’ve just finished recharging your tracker.

Contact support.
When you order a Solid GPS tracker you can contact Australian support at any time if you need any help with your tracker.
