North Korea’s recent GPS signal jamming operations on the Korean Peninsula have highlighted “life-threatening” vulnerabilities in the US Army’s Rifleman Radios. cell phone jammer Rifleman Radios are intended for frontline soldiers to locate and communicate, but their built-in GPS chips only receive civilian signals that are susceptible to jamming. signal jammer This incident has also triggered a discussion on whether low-cost civilian GPS chips should continue to be used in military equipment.

　　Vulnerability of Non-Military GPS Chips

　　GPS satellites provide two different levels of signals: anti-jamming signals designed for military use and signals open to civilian use but susceptible to jamming. GPS jammer The US Army chose to install chips that receive civilian GPS signals in rifleman radios, a decision that was ostensibly a “convenient and economical” solution. Wifi jammer However, it is precisely the use of this cheap civilian chip that makes the equipment vulnerable to enemy jamming. Jules McNeff, vice president of strategy and projects at Overlook Systems Technologies Inc., pointed out that although the original intention of choosing civilian chips was to reduce costs, every GPS jamming incident raises questions about this choice.

　　The Real Threat of GPS Signal Jamming

　　GPS jamming is not a new phenomenon. As early as 2022, Lt. Gen. Ronald Burgess, director of the U.S. Defense Intelligence Agency, warned the U.S. Senate that North Korea had installed Russian-made high-power jammers on vehicles in border areas that were capable of blocking GPS signals within a range of 30 to 60 miles. What's more serious is that North Korea is stepping up the development of GPS jammers with longer ranges, further increasing the threat to GPS systems in the region.
