The three most serious threats facing global navigation satellite systems come from sabotage, deception, and anti-space capabilities. Ground receivers can interfere with commercial equipment. As long as cell phone jammer are deployed, satellite receivers cannot access satellite signals. As a result, affected users will lose navigation capabilities, and systems that rely on timing signals (such as transportation networks) will not work. The recent NATO exercise Trident Junkture reported on this type of ground disturbance, which affected Norwegian ships. In fact, some people mistakenly guessed that this might be the cause of the sinking of Helge Ingstad. At present, sabotage only applies to receivers, not to signal satellites, but as the country expands the scope of its auxiliary military operations in space, this situation may change in the short to medium term.
Anyone who has played CODOL knows that in this type of game, the selection and adjustment of tactical equipment is very important to the personal experience of the game. Even at critical moments, some cautious props can save your life. For example, cell phone jammers and cell phone interceptors can not only interfere with enemy radars, but also hide the location of friendly forces. The main function of the jammer is to shield the visual information on the enemy map in a specific area, such as drone detection and a small map of the enemy invading the area. Some high-performance drone jammers can actually shield the 2.4G and 5.8G WiFi frequency bands commonly used by commercial or commercial drones on the market to prevent unattended aerial photography and detection. Needless to say, the small jammers on the market can limit the mobile phone signal launched by the rocket to 500 m with a radius> 20 m. It only blocks phone signals, so you don’t have to worry about other electronic devices being affected. When the nearby signal is shielded, the mobile phone usually shows no signal, searching the network, etc.
