GPS signal jamming devices are the biggest threat to the United States

Perfectjammer 2019-12-10

Russia's advanced jamming and electronic warfare capabilities are well known. The conflict in the east of Ukraine involving Russian-backed separatists, who take advantage of Russian capabilities and assistance, and the Ukrainian armed forces provide the US military with a unique perspective to examine Russia's capabilities.

The function of radio GPS jammer is to intentionally block or interfere, essentially to "block" the wireless signals to disrupt communication between the transmitting device and the receiving device (i.e. drone). Traditionally, jamming has been used to disrupt enemy communications on the battlefield. Scramblers emit noise on the same frequency, which stifles the recipient's ability to understand the message being sent. In some countries, the wireless jammer is used as a detection device to block unwanted radio signals from neighboring countries to be received by their citizens. Other types of jammers prevent the signal from being received without using noise, so that the blocked portion is not aware that a scrambling device is being used. WiFi jammers are designed to disrupt signals in the 2.4 GHz range, disrupting most home WiFi systems, Bluetooth enabled devices, and drones operating at 2.4 GHz......

Moreover, it is unclear whether US systems could be susceptible to similar capabilities or whether US systems have been appropriately hardened to counter the blockage. Despite Hodges' comments about US observations on Russia's capabilities in Eastern Europe, the US military told C4ISRNET that it was unable to comment because its mission in Ukraine is located in the western part of the country. knowledge of the situation.

The jammer-shop ram gun, according to its product brochure, uses signal jamming on the 2.4 and 5.8 GHz frequencies. It also has a technology able to block the GPS and the Russian equivalent, GLONASS.

A number of anti-drone technologies have emerged over the last year using lasers or "directed energy UAS countermeasures" based on "radio frequency interference". This latter approach is developed and promoted by Perfectjammer, the applied science and technology laboratory. who recently demonstrated a drone jammer called "Drone Gun"
