The quick answer is that any sufficiently solid substance may easily block a GPS signal. The GPS signals can be scrambled by aluminum paper, concrete, or any wooden cover. GPS signals can pass through plastics and fiberglass, which is why GPS devices can maintain signal strength even while disguised within a car.
Any electrically conductive metal will reflect and absorb the device's incoming and outgoing signals and interfere with its operation. Wrapping a GPS tracker in aluminum foil is enough to do the job—although copper and even silver work as well. This is an incredibly cheap and easy method of GPS jamming.
For instance, wrapping things like aluminum foil around the GPS receiver creates a Faraday Shield, which blocks the GPS signals. Similarly, wet trees and plastic or tin containers filled with thick materials can also scramble these signals. These signals will help you protect your GPS data.
Most of the trackers are added by the owner, but any person can equip a vehicle with such a device without the knowledge or consent of the owner. If you suspect that your vehicle has been outfitted with a GPS tracker without your knowledge, there are some simple steps to take to determine whether you are being tracked.
If you have any seat covers on the interior of the vehicle, pull them up to see if the tracker has been tucked underneath. Check underneath the seats and the floor mats. Shine the flashlight underneath each of the seats and run your hands along the bottom to feel for any potential trackers.

If you want to know, “Can you track a car without GPS.” Yes, you can use your smartphone to track your car's location. There are several apps available that can do this, such as Glympse and Find My Phone. These apps work by using the GPS on your phone to track your car's location.
This is dependent on the type of tracker you use. Most, if not all trackers operate by using the car's battery/electrical system to power it. So for some models of car trackers, they will not track the location of the vehicle if it is off.
GPS tracking protects vehicles against theft and boosts the likelihood of recovery. In today's era, most cars are fitted with GPS devices. But if an owner's new car isn't fitted with this device, they don't need to worry as it is not mandated by the law to have GPS in cars. Still, car owners can benefit much from GPS.
Yes, there are many apps that can detect if a GPS tracker has been installed on your cell phone. If you have an Android phone you can download Certo Mobile Security for free from the Play Store and quickly scan your phone for GPS tracking apps and other malware.
Once a GPS tracking device is located, it can be disabled. Beyond simply removing the battery, it is possible to stop the GPS signal. It's important to remove the device completely and dispose of it so it does not continue transmitting your location.
Tracking devices look different depending on their manufacturer and purpose, but some general guidelines can help you locate one on your vehicle. It will typically look like a small box with a magnetic side. It may or may not have an antenna or a light on it.
Wrap the Device in Tinfoil
This blocks out any cellular or satellite signal from reaching the device. Any electrically-conductive metal will interfere with incoming and outgoing GPS signals. This is a cheap and easy method to prevent yourself from being tracked.
The S7 Tracker Locate has been specifically designed as an anti-jamming tracker, and many individuals who have been the victim of vehicle theft, where the signal has been blocked will opt for this device.
TrackerTM - the market leaders in stolen vehicle recovery
TrackerTM's Thatcham-approved S5 and S7 vehicle trackers include patented VHF technology, which means that, unlike standard GPS trackers, TrackerTM's signal cannot be blocked by being underground, in a garage or in a shipping container.
While navigation devices have been seen inside vehicles dating as far back as 1930 and the first satellite navigation system being the United States Navy built TRANSIT, it's specifically the GPS system that excelled and continues into the present time.
