President bush was said to have even called Russian President vladimir putin. Germany’s military technology magazine reported that in the end because of a great disparity in strength, and Iraq to get only a handful of GPS jamming device at the time, can’t connect the network, these devices are eventually destroyed by us troops. In recent years, south Korean media have reported that north Korea has had a number of massive GPS interference with South Korea, and its technology has come from Russia.
In recent years, with the rapid development of modern communication technology, the use of high-tech cheating in examination room means emerge in endlessly, the university entrance exam cheating tools by the initial pager, mobile phone, and then the handset and then to today’s digital products, appearance is for the ruler, rubber, glasses boxes, stationery bags, watches, cheating tools such as mineral water bottles, exams have emerged in various countries. In order to prevent cheating, the authorities have effectively prevented and discouraged cheating in the examination room by using mobile phone block apparatus, metal detector, wireless signal jammer and warning suppression equipment.
Russia’s installation of jammers on mobile-phone towers is an unconventional move, but its logic is justified militarily. As things stand, the U.S. has a big advantage in cruise missiles, drones and GPS systems. American-made cruise missiles, such as tomahawk cruise missiles, have electronic devices designed specifically to combat GPS jammer. Raytheon Company, the manufacturer, noted that an anti-jamming GPS receiver called AGR could “achieve continuous satellite tracking in the presence of high levels of hostile interference”.
