GPS Jammers or GPS Blockers and the Law - Do they Work? (2024)

FAQs

Are GPS blockers legal? ›

The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle.

Do GPS Blockers work? Yes - Gps Jammers or blockers do work on but have limited range and can easily be detected by modern trackers with anti jam technology such as the back2you.com Guardian Self install Live Tracker Police forces can easily detect jammers using jam detecting scanners.

Anti-jamming and anti-spoofing systems can distinguish true GPS signals from jammers and spoofers, enabling GPS location and timing services to continue even while under attack. CRFS recommends that law enforcement implement a wider strategy of spectrum monitoring to combat the rise in GPS jamming activity.

In six states (California, Florida, Hawaii, Louisiana, Minnesota, New Hampshire and Virginia) laws more broadly prohibit the use of electronic tracking devices, not just on vehicles, and not just in the context of stalking, but when they are used to determine the location or movement of a person without consent.

Without highly advanced, military-level technology at hand, it is virtually impossible for the average consumer to definitively detect a cell phone jammer. However, if you suspect illegal activity of this sort, contact law enforcement or file a complaint with the FCC.

In timing applications, jammers can disrupt the GPS signal, causing the underlying systems to lose their ability to synchronize their internal clocks and, in turn, their ability to stay in sync with the rest of the network.

The Trick: It sounds like a myth, but wrapping a GPS tracker in aluminium foil can block its signals. This rudimentary method is surprisingly effective—and temporary. The Countermeasure: This method is usually a temporary fix, as drivers need to remove the foil for their own navigation purposes.

Jamming interferes with GPS asset tracking, also known as fleet tracking or telematics, which is a critical source of business data to many companies. Fleets use telematics to track and manage fuel use, idling, driving behavior, engine health and other activities.

One effective way to counter GPS jamming is to use Controlled Reception Pattern Antennas (CRPA) instead of standard GNSS antennas. CRPA are phased array antennas that shape their signal reception beams—minimizing the impact of jamming signals while optimizing the reception of GPS satellite signals.

They do so easily by monitoring the return frequency of the jammer during the time that the gun doesn't transmit – a dead giveaway of the user of an active jammer. In some cases, a jammer may inadvertently produce a higher indicated speed on the officer's radar gun!

Which GPS tracker Cannot be jammed? ›

S7 TRACKER LOCATE

As well as using the most advanced GPS/GSM technology currently available, the Tracker Locate also employs VHF technology. VHF (Very High Frequency) technology is an undetectable tracking frequency that CANNOT be jammed or blocked by any equipment thieves might be using.

Every time tech is used to fight crime, the bad guys just get better gear. The only crime-fighter who manages to always have the better gadget is Batman. Now car thieves are using GPS jammers to blot out the satellite signals that some antitheft services use to locate stolen automobiles. It's not hard to do, either.

GPS trackers are small devices that use GPS and cellular technology to monitor a car's location in real-time. Some trackers are visible, but many are tiny and lightweight, making them easy to hide. In fact, many trackers are smaller than a deck of cards, so they can be used for spying without being noticed.

The best way to check for an implant would be to have an X-ray performed. RFID transponders have metal antennas that would show up in an X-ray. You could also look for a scar on the skin. Because the needle used to inject the transponder under the skin would be quite large, it would leave a small but noticeable scar.

The police can install and set up the tracking device without your knowledge and only must notify you that you were tracked by a GPS device within 10 days after the tracking period ends. In addition, the police can track you for longer than 30 days if they show good cause for an extension of the initial 30-day period.

The signal from a GPS tracking device can also be blocked by a jamming device. GPS Jammers work by producing a white noise radio signal that is transmitted around the same frequency as the GPS satellites. This can block out the signals to GPS tracking devices and navigation systems.

Digitpol's JamDetect will detect GPS Jammers in use at car parks and can alert a control room, security guards, law enforcement within seconds of detection. The detection of a jammer can prevent car thefts, robberies and crime. An output is also available to trigger a siren or LED that a jammer is detected.

Unlike GPS jammers, audio jammers are not illegal because they don't interfere with signals from government organizations or jeopardize public safety.
