Design and Functionality of HIMARS

         HIMARS is a mobile rocket launch system designed to strike enemy targets quickly and accurately. signal jammer The missiles it carries usually rely on GPS guidance and can hit long-range targets. They are particularly suitable for high-intensity and dynamically changing combat environments. ​​GPS jammer However, the guidance system of HIMARS has also become its weakness: any interference with the GPS signal will reduce its attack accuracy. This weakness was exploited by Russia and became a key factor in its successful weakening of the effectiveness of HIMARS. drone jammer

Russian electronic warfare jamming technology

　　Russia's investment in electronic warfare has enabled it to develop advanced jamming technology that can effectively affect the GPS systems of enemy weapons. Specifically, Russia's electronic warfare system can emit conical electronic waves into the sky in a specific area. This waveform can cut off the weapon system's connection with GPS satellites, causing missile guidance to fail. The system greatly reduces the accuracy of HIMARS missiles, causing them to frequently deviate from their targets, even by more than 50 feet.

Impact on the battlefield

　　In the Ukrainian battlefield, HIMARS was originally seen as a "game-changing" weapon, but Russian electronic warfare jamming greatly reduced its effectiveness. Ukraine has suspended the use of the system because its loss of accuracy has reduced its target success rate to less than 10%. In addition to HIMARS, weapons such as Excalibur GPS-guided artillery shells have also been interfered with, forcing the Ukrainian army to face the problem of reduced battlefield equipment effectiveness.
