Introduction On the battlefield in Ukraine, GPS jamming has become an important part of Russia's electronic warfare, making it difficult for the Ukrainian army's drones and high-end weapons to operate normally.cell phone jammer To deal with this complex electronic warfare threat, Zephr, a US company, is developing an innovative tool based on mobile phone networking to help locate and counter these jammers. This article will take a deep look at how this technology works and analyze its future potential. GPS jammer

　　1. The impact of GPS jamming on the battlefield On the modern battlefield, GPS technology provides vital support for drone navigation, precision strikes, and troop dispatch.Wifi jammer However, GPS signals are extremely susceptible to jamming, especially in countries like Russia that are proficient in electronic warfare. In Ukraine, the Russian army jammed GPS signals to cause Ukrainian drones to lose control and even force them to land. This poses a huge challenge to the combat efficiency of the Ukrainian army. signal jammer

　　2. Zephr's mobile phone networking solution Zephr has proposed a new response strategy: through networked ordinary mobile phones, a large distributed antenna network is formed to work together to detect the location of jammers. The GNSS sensor on the mobile phone can detect whether there is signal interference and find the location of the interference by comparing the data of multiple mobile phones. Unlike traditional high-cost detection equipment, this system relies on common consumer devices, which is low-cost and easy to deploy on a large scale.
