Does aluminum foil block GPS tracking? Aluminum has some ability to block GPS tracking. Wrapping a GPS device with aluminum foil can affect the transmission signals. GPS readings will be untraceable and inaccurate when there is aluminum around the device. Most of the offenders use foil to do illegal activities. So no one will know their location anymore. This article will help you with more details regarding the factors mentioned above.
Why Do People Block a GPS Signal?
GPS stands for Global Positioning System. Vehicles, dog belts, etc., are some of the things which include GPS. This technology is essential because we no need to worry about the safety of valuable items. If someone has stolen it, the owner can find the exact location with the help of GPS. But some devices can jam the GPS signals.
The most common tech gadget is the GPS jammer. This is a tiny gadget with a very high radio frequency. As a result of the frequency, the GPS signals are jammed. GPS receivers get the signals with the help of satellites. But the jammers interfere with radio frequencies while the signal is transferring to the satellites. Due to the interference, the GPS receiver cannot get the exact locations.
The GPS Jammers are illegal to sell. If someone does business with the jammers, they will be sent directly to the court. Despite that condition, several types of GPS jammers are available online.
Does Aluminum Foil Block GPS Tracking?
Yes, aluminum foil can affect the signals of the GPS. All the GPS modules have the same system embedded. In this process, there is a signal transmitter and a signal receiver. Once a GPS tracker is connected to a vehicle or something, the GPS signal transmitter sends the signal to the satellite, and then the receiver gets the relevant signal correctly.
That’s how the GPS works. Any GPS can locate the exact correct location without any errors. But what will happen when aluminum foil is wrapped around a particular GPS device? This is a successful way to jam any GPS signal. Aluminum foil is an excellent electric conductor. When the aluminum foil wrapped around the GPS is transmitted, it creates a wall for transmitting signals.
As a result, the signal will not reach the exact receiving location. Somehow it transferred, and the data will be incorrect. Aluminum can absorb all electromagnetic waves. Radio signals like GPS is a good example of that.
If anyone is willing to block a particular electromagnetic wave, aluminum foil will be a beneficial product. There are several alternative products to do this process, but they are expensive. Using aluminum foil will do the same thing.
Does Aluminum Foil Block Cell Phone Signals?
As we already mentioned, aluminum is capable of blocking GPS signals when wrapped around a device. The ability to be able to conduct electricity is the reason for this blocking ability. When a wave comes to the aluminum, it acts as a barrier for them; When considering cell phones, the same answer can be given because aluminum can block the radio waves in the cell phone.
Then the cell phone signal will be lost. Due to its strong dispersion efficiency capability, aluminum is a good GPS blocker. As a result, aluminum foil doesn’t have to be extremely thick to work. However, to guarantee that it entirely blocks signals, we advise that you tightly wrap your cell phone in aluminum foil, ensuring there aren’t any gaps or holes that could compromise the shield’s effectiveness.
Is There Anything More Accurate Than GPS?
Are there any other positioning systems? Yes, of course, there are several other positioning systems available today. But they are still not given to the citizen. According to the data, GLONASS and Galileo are the two main successful positioning systems in the world apart from the GPS.
The United States owns GPS, Russia has GLONASS, and the European Union is working on Galileo. That’s the simplest way to tell the three systems apart. After the GPS’s development, Russia started developing its own project with GLONASS. The main reason for this project is to hide the Russian detail from the United States. There is a massive conflict between the two countries.
But when it comes to actual use, all the other characteristics matter much more. Satellite navigation systems, including GPS, GLONASS, and Galileo, all seem to be the same technology. They differ from one another in a variety of ways, including each system’s network of satellites and pinpoint precision. But now, GPS is only the accurate positioning system available.
Limitations of GPS
GPS can be limited due to several factors. Most of the time, GPS signals are inaccurate when you stay indoors. GPS signals will be blocked due to the walls. When the GPS signals have blocked, the accuracy of the information will not be good.
And there are alternative ways to limit the GPS. Aluminum foil is also a limiting factor for GPS signals. The whole article represents that. Some satellite problems may also affect the limitation of the GPS.
Yes, aluminum foil can block GPS thoroughly. But blocking a GPS signal is completely illegal. So, you have to think twice before doing this type of thing. Wrapping aluminum foil around a GPS tracker will reduce the incoming radio signals. Then the location details will be inaccurate.
Not only aluminum foil, but there are also GPS jammers available in the market if you need to block the radio signals perfectly. Sometimes the effect of the aluminum foil will be reduced due to the wrapping quality. If there are holes in the foil, the signals will reach the GPS tracker. At that time, the GPS receiver will get the exact location details without errors.
We think now you have the perfect idea about the connection between aluminum foil and the GPS. Read the full article without skipping to get the advantage of the article. Till the next time, Adios.
