Detect GPS & Signal Jammers: Essential Knowledge for Fleet Managers

by

Fleet owners and operators have witnessed a significant shift in the industry towards the integration of technology across every system. The widespread adoption of automated fleet management and Global Positioning Systems (GPS) tracking solutions has revolutionized operations, enhancing driver safety and compliance adherence. However, devices known as GPS jammers and cell phone jammers can disrupt the critical functions of GPS tracking, posing challenges for fleet owners seeking to maintain effective fleet tracking and control. Although the use of these jammers is illegal and uncommon in the United States, they still pose significant risks and issues for those in the transportation industry. Fleet managers must remain vigilant to ensure the integrity of their tracking systems and mitigate any potential disruptions caused by these devices.

What Is a GPS Signal Jammer?

GPS signal jammers, powerful RF transmitters, effectively disrupt communication devices like cell phones, GPS, Wi-Fi, and toll readers. By emitting stronger radio signals than GPS satellites, these jammers create a “noise” that fools gps tracking systems, making them believe no GPS signals are accessible. This technique, known as spoofing, works by overshadowing satellite signals with a shorter range but higher power output, rendering GPS receivers useless. In a nutshell, GPS jammers offer a compact solution to block unwanted signals, ensuring privacy and security in various situations.

What is the Appearance of GPS Jammers?

GPS jammers, sourced from multiple manufacturers, exhibit a wide range of shapes, sizes, and dimensions, making them elusive within a vehicle’s interior. Typically, these blockers operate over a short range and are compact enough to be powered via a cigarette lighter or iPhone socket, effectively disrupting signals to GPS trackers mounted inside the car’s cockpit.

Is it Illegal to Use GPS Tracking Signal Jammers?

GPS jammers and signal blockers, though illegal in the US and Canada, are still easily accessible online. The FCC strictly oversees radio communication devices and has taken measures against the use and sale of signal jamming devices. However, these devices continue to be available, posing challenges to regulatory authorities.

Does using GPS Jammers elevate security threats?

Fleet owners should be vigilant about any modifications drivers make to their vehicles, as GPS jamming devices can pose significant risks. While some may view these devices as a way to circumvent telematics requirements or protect personal privacy, their use can introduce insecure hardware into the vehicle. This can provide hackers with an opportunity to access the onboard telematics systems and tamper with crucial GPS functions like navigation and positioning. Furthermore, gps jammers also threaten public safety and security. In the event of a vehicle theft, these devices can hinder law enforcement’s ability to locate the stolen vehicle, disrupting a company’s scheduling and potentially impacting its bottom line if the vehicle remains missing. Therefore, it is crucial for fleet owners to closely monitor any changes made to their vehicles to ensure the safety and security of their fleet.

How does GPS jamming affect fleet operations?

Fleet managers rely on precise driver behavior and vehicle health data to maintain safety and cost-efficiency. However, GPS jammers disrupt accurate tracking, obscuring vital information like traveled distance, road time, speeding, and harsh driving. This data gap can lead to compliance issues, fines, and inadequate vehicle maintenance, ultimately hurting both revenue and safety. To avoid these risks, it’s crucial for fleet managers to ensure uninterrupted GPS signal for comprehensive monitoring.

How to Mitigate the Usage of GPS Signal Jammers?

Fleet owners and managers must grasp the capabilities of their GPS tracking devices and navigation systems. This understanding is crucial to recognize when a device is potentially being hampered by a GPS jammer. Monitoring Non-Reporting Unit (NRU) trends can assist in identifying potential issues with GPS trackers installed in vehicles. Additionally, it’s essential to comprehend network weaknesses, exposures, and vulnerabilities that hackers could exploit. Regularly scheduled IT network maintenance and troubleshooting can significantly reduce the possibility of data tampering, thereby preventing future issues. Lastly, clearly communicating the company’s vehicle usage policies and policies around prohibited devices like GPS jammers to employees can help discourage the use of such devices in the first place.

Is Using a GPS Blocker Illegal?

Using a phone jammer, GPS blocker, or any signal jamming device to deliberately disrupt authorized radio signals breaks federal law. This applies everywhere, whether it’s a business, classroom, home, or car—no exceptions. So, before considering using these devices, be aware that such actions are considered illegal.
