We all know that GPS plays an important role in our lives. Mobile navigation cannot be separated from GPS positioning, and the car navigation system is paralyzed away from satellite positioning. GPS signals play a pivotal role in the military field, and what happens once the GPS signal is suddenly cut off.
According to media reports, the recent disruption of GPS signals in the Mediterranean was caused by the sudden cut-off of the United States, which had a serious impact on Syria and the Russian military. Since many devices in these areas have used GPS positioning information, many civilian and even military equipment have been affected. Therefore, many advanced weapons deployed in Syria have also lost their functions. Missiles and fighters have lost their combat power and become useless. Scrap iron.
This is because the GLONASS system has not completely covered the relevant areas, and many advanced military equipment are used in the US GPS system. Earlier, the Chinese army had also been targeted in this regard. In the Taiwan Strait crisis, the United States closed GPS navigation, causing the Dongfeng 15 missile launched by the Chinese exercise to be blindfolded and directly shot.
Before the Beidou satellite system did not appear, GPS has always been a monopoly in the navigation field. Although GPS is the mainstream navigation system in the world, there are still many shortcomings that cannot be solved. Such as the impact of complex meteorological conditions, the impact of the geographical environment and so on. The US government has made it clear that GPS signals will be turned off for the benefit of the United States when necessary.
There is an old saying in China: "There is a mother who is not as good as oneself." The Chinese themselves developed a national weapon such as the Beidou satellite system and were able to determine their own destiny. Compared with GPS, Beidou navigation system has a prominent advantage, that is, the user terminal of Beidou system can be used for short message communication, which greatly meets the needs of users.
In military terms, GPS satellite signals determine the military lifeline of a country. In terms of people's livelihood and life, GPS signals are also very important. However, not all GPS is used for legitimate purposes, such as GPS trackers, which help us. While tracking old people, children or some pets, we may also become targets of others' surveillance. This poses a serious threat to our personal freedom and life and property safety. We can use GPS jammers to block GPS tracking.
The GPS jammer is a signal interception device that specifically blocks GPS. When the equipment starts to work, it can form a shielding interval within a certain range, that is, a "protected area". The GPS signal located in the interval is intercepted, so that it cannot be Position tracking, some high-power GPS signal jammers can block mobile phones and even WiFi signals, generally used in the home or device in the car, as those mini gps jammer can be carried around, in the pocket, and the price is very cheap.
