GPS jammers, transmitting low-power signals to disrupt GPS reception, have become a tool of choice for car thieves in the UK, raising concerns among experts that their adoption by criminals and terrorists in the US is imminent. These devices, which fool GPS receivers into believing satellites are inaccessible, offer a range of nefarious applications: from evading toll charges and confusing police, to targeting unsuspecting iPhone users in pranks. However, the gravest concern lies in their potential for misuse by lawbreakers seeking to elude law enforcement or, even more alarmingly, by terrorists who might deploy high-powered versions to wreak havoc on airplane navigation or military operations. The societal risks posed by these jammers are profound, and their purchase and use in the US are strictly prohibited. The Federal Communications Commission (FCC) takes a hard line against gps jammer ownership, vowing to prosecute and imprison anyone who dares to utilize them.
Easily accessible online, gps jammers are being touted as a necessary tool, with proponents arguing for their continued availability. Despite their low cost, ranging from just $50 on various online platforms as reported by Fox News, to $430 for the GJ6 jammer sold by Jammer-Store.com in Sweden, or even $49 for the Car Cigarette Anti-GPS System from Hong Kong-based Brando Workshop, these devices pose significant risks. According to David Last, an Emeritus Professor at Bangor University in the UK and a renowned expert on the criminal use of GPS jammers, the widespread integration of GPS into our transportation, manufacturing industries, and economies makes them a prime target for disruption. He warns that telecommunications, in particular, are vulnerable, as GPS provides the essential timing for most telephone systems, the Internet, and even phone cells in the US. However, advocates of these devices maintain that they serve a legitimate purpose and that individuals should have the freedom to purchase them, a freedom that currently remains unrestricted.
Jammer-Store.com offers a unique perk for shoppers: free worldwide shipping via leading providers like UPS and FedEx. One site even highlighted their specialized models tailored for the U.S. market. According to Michael Kharkovoy, the CEO of Jammer-Store, GPS jammers provide an effective solution for those seeking to evade unwanted tracking. These devices, which can be discreetly stored in a vehicle or a bag, are particularly useful in situations such as preventing a suspicious spouse from using a GPS tracker like Zoombak to monitor one’s movements. Kharkovoy emphasizes that their newest model, the GJ6, is designed to block a wide range of tracking systems, including civil GPS systems operating on L1, L2, and L5 frequencies. Operating the GPS jammer is as simple as flipping a switch, he adds. However, Bruce Romano, the legal adviser at the FCC’s Office of Engineering and Technology, cautions that the convenience of using a jammer does not justify its use.
The Air Force, responsible for deploying and maintaining GPS satellites, recognizes the vulnerability of GPS systems due to their widespread public use. Andy Roake, chief of current operations at Air Force Space Command Public Affairs, explains that GPS design includes measures to guarantee signal availability in a war fighter environment. However, Romano warns that hiring a detective to sweep cars or personal belongings for GPS receivers, while possibly seen as a solution, can have unintended consequences. Such sweeps may affect a range of critical devices, causing problems unknowingly. Romano emphasizes that besides being potentially illegal, criminals may mistakenly believe they can evade detection by customs with these devices.
Improving jam-resistant capability remains a continuous effort in our GPS constellation development. This crucial aspect of signal availability has been a primary focus in enhancing the satellite constellation, ground segment, and military user equipment. While we cannot divulge technical specifics due to the sensitivity of disclosing capabilities to potential adversaries, we prioritize maintaining the integrity of our systems. Government agencies maintain silence on the specifics of detecting or dissuading jamming equipment, as well as the upgrades in next-gen GPS satellites to bolster anti-jamming measures. Notably, the Bush Administration introduced a high-power, ground-based system called Enhanced Loran (eLoran) in 2008, intended as a contingency plan for GPS jamming. However, the current administration has not indicated any plans to proceed with eLoran, leaving the U.S. in a precarious position regarding jam resistance measures.
GPS and cell phone signal jammers, though not cutting-edge technology, can cause significant signal disruption. These devices, resembling illegal cell phone jammers, primarily affect GPS systems, potentially leading to confusion in aircraft cockpits as pilots adjust to backup navigation. Maritime shipments reliant on GPS for port location may also encounter difficulties. Ronald Repasi, the FCC’s Deputy Chief, emphasizes that selling, importing, owning, or operating GPS jammers is unlawful in the U.S., and the FCC actively pursues violators. He warns of the potential risks posed by negligent use of these devices, especially considering airplanes often rely on ground-based radar and backup systems independent of satellites, while military personnel utilize a dedicated GPS network.
Repasi emphasized the significance of jamming device’s capability. He explained that devices with higher power possess a broader range, offering more potential for interference across wider areas compared to their lower-powered counterparts.
MICRO GPS JAMMER: What Is It?
The MGJ, a cutting-edge EW Jammer, is specially crafted to disrupt GPS systems, utilizing advanced active EW jamming and deception techniques. Its innovative design ensures that adversaries cannot effectively operate their GPS systems, providing a critical advantage in tactical situations. What’s more, the MGJ is not just powerful but also highly portable, lightweight, and durable, making it an ideal choice for transportable use. To further enhance its capabilities, we offer the MGDS, a comprehensive EW-GPS combat system. This system, centered around the MGJ unit from TMC Design, includes four antennas operating within the GPS frequency range and a quick-deploy tower. This allows for rapid site setup and teardown, meeting the demands of mobility and ensuring swift, effective deployment in any situation.
