Can GPS Tracking Be Wrong
6 Reasons Can GPS Tracking Be Wrong (Plus Solutions)
Is your GPS tracker not working?
Your GPS tracker could be wrong for a few reasons, but it’s most likely either the weather or the quality of the device. If the hardware is broken or the software hasn’t been updated, it could interfere with the signal and cause it to show the wrong location (or no location at all).
Don’t worry, in this article we’re going to show you the most common reasons your GPS isn’t working along with some solutions to those problems.
We’ll get that tracker working in no time.
NOTE: There’s a chance that your GPS tracker just isn’t a high-quality model. We see people complaining about cheap trackers all the time here at the GPS Tracker Shop. In that case, you might just have to upgrade to something a bit better.
First, How do GPS Trackers Work?
First, you need to understand how these devices work, so you can understand what might be causing them to show an inaccurate location.
GPS trackers work by communicating with satellites to determine the location of a device. The tracker receives signals from multiple satellites. Based on that data, it calculates its position on your vehicle.
However, these signals need a clear path to the tracker.
Obstructions like tall buildings, tunnels, or even dense trees can block or bounce the signals, causing inaccurate location data or making the tracker temporarily stop working.
Long story short, GPS trackers are insanely accurate, but if something like weather or positioning is screwing up the signal, it can show an incorrect location.
6 Factors That Can Cause GPS Tracking To Be Wrong
If there’s a problem with your GPS, it’s most likely because of the positioning of the device, a hardware/software issue, or the weather.
No matter what the issue is, there’s a solution. Let’s jump into the factors that could be causing your GPS tracking to be wrong.
1. GPS Receiver Quality
This is the easiest one. Maybe your GPS receiver just sucks.
If you’ve bought a cheap, plastic toy for $10 off of Amazon, then it’s probably not going to be that accurate. Or, if you’re using something like Apple AirTags for tracking a car across town, then it’s not going to work. Those things are meant to track backpacks and car keys.
If you get a legit GPS tracker made for tracking vehicles, you won’t have these problems. Sorry to be blunt, but it’s the truth!
2. Satellite And Device Positioning Positioning
If you aren’t getting a good signal, there could just be something wrong with the satellite network.
That’s pretty rare, though. The US Military is usually on top of things.
The more likely reason is that you’ve placed the device in a bad location. Don’t hide it too far inside the car, as this could cause the satellites to drop the signal.
Make sure that wherever you put the device, it has a clear line of sight to the sky. Or at the very least, a clean line of sight to the ground. The signals can bounce off the ground and up to the satellites no problem.
3. The Weather
Did you know the environment can affect your GPS accuracy? It’s true. Things like bad weather and tall buildings can mess with your signal.
For example, heavy rain or thick clouds can weaken the satellite signals, and even solar flares can cause problems. In cities, skyscrapers might block or bounce signals, making your GPS act up (we’ll get to that in a second).
The solution to this is to pick a device that can handle these conditions like the SpaceHawk GPS tracker. Always go for tech that’s built to work well in different conditions. That way, you’ll get more reliable and accurate tracking, no matter what.

4. Multipath Errors and Signal Obstruction
Multipath errors occur when satellite signals bounce off surfaces, confusing the tracking system.
Signal obstruction due to physical barriers such as tall buildings, trees, or even certain weather conditions can also create inaccuracies.
Also, keep in mind that most GPS trackers won’t work underground. If someone is parked in an underground parking garage, you’ll drop the signal. Don’t panic, it’ll come back.
The solution here is to get yourself a GPS tracker that has an ultra strong signal like the SpaceHawk. We know we keep recommending it, but it really is the strongest, most accurate tracker out there.
The other solution is to just wait until the vehicle has exited the garage for the signal to come back.

5. Cold Start
When your GPS device boots up with no prior location data, we call this a cold start.
This could make your GPS short circuit.
Your device needs extra time to catch satellite signals and determine where you are. If you manage a fleet, you need a GPS tracker that can handle a cold start. This will ensure that your signal is always available and accurate.
The solution here is buy a GPS tracker that can handle a cold start or to just wait it out. Give the GPS some time and it’ll work. You may have to restart it though.

6. Software Issues
If your GPS isn’t working, your software may just be out of date.
GPS devices are just like smartphones or apps: They always need updates. In this case, just make sure you update the software as often as possible. If there are any issues, contact the support team.
We recommend companies like LandAirSea Systems, US Fleet Tracking, and SpaceHawk GPS. They’ve got the best, most reliable software and best support teams.

Now you know how to choose the best tracking system for accurate, real-time tracking, and efficient operations.
Understanding The Dangers Of GPS Errors
When GPS trackers go wrong, it can lead to deadly consequences.
According to Psychreg.org, GPS errors contribute to over 200,000 accidents annually in the U.S. Studies have shown a direct correlation between GPS inaccuracies and road incidents. These errors often arise from outdated maps, incorrect directions, and driver distraction. In fact, the National Highway Traffic Safety Administration (NHTSA) has found that between 25% and 30% of all car accidents in the U.S. are linked to driver distractions. One of the primary culprits? GPS navigation systems. Adjusting a GPS while driving, as per NHTSA studies, can increase the risk of a crash by 23 times!
Make sure to invest money in a proper GPS tracker, especially if you’re a business. It’s worth it.
Can GPS Tracking Be Wrong – Frequently Asked Questions
Can a GPS tracker be wrong, and what might cause inaccuracies in GPS location tracking?
Yes, a GPS tracker can be wrong. Inaccuracies in GPS location tracking are usually due to multipath errors, signal blockage, satellite geometry, or environmental conditions. Upgrading receiver design features and being aware of physical obstructions can improve GPS tracker accuracy. Sources like the Global Positioning System Directorate explain these technical details in more depth.
How important are GPS satellites and signals in space for the accuracy of a vehicle GPS tracker?
Extremely important! GPS satellites emit signals in space, which vehicle GPS trackers receive to calculate location. The accuracy depends on satellite geometry, signal strength, and receiver quality. If the signal is obstructed or weak, the GPS location may be incorrect. The quality of the signal in space and the alignment of the satellites play a vital role in the overall accuracy.
Are there ways to improve the accuracy of a GPS tracking system?
Yes, you can improve the accuracy of a GPS tracking system by keeping your software up-to-date, placing the receiver in the right places, and getting a waterproof case to protect it from the elements.
You can also minimize signal blockage by considering the environment where the GPS is used. Understanding these aspects is essential for getting the most out of your global positioning system.
How accurate are GPS tracking devices, and what affects the position accuracy?
GPS tracking devices are generally accurate within a few meters. However, factors that affect position accuracy include the quality of the receiver design, satellite geometry, environmental conditions, and potential signal blockage. Staying up-to-date with the latest GPS technology advancements and understanding these influencing factors will allow you to maintain or even improve the accuracy of your tracking system.
What role does the receiver design play in GPS tracker accuracy, and can it cause the GPS tracker to be wrong?
Receiver design is extremely important for GPS tracker accuracy. A well-designed receiver can effectively interpret the signal in space from GPS satellites to produce an accurate location. Conversely, a poor design may lead to errors, causing the GPS tracker to be wrong. Investing in quality receiver design features not only enhances accuracy but also adds reliability to your positioning system, something that the US Global Positioning System (GPS) Standard Positioning Service (SPS) emphasizes.
