August 28, 2004, the United States - McGregor said: During the Iraq War, the Iraqis destroyed GPS navigation data, making it impossible for American cruise missiles, bombers, etc. to locate bombing targets.
GPS is a strategic tool. It was later confirmed that the Iraqis had used GPS jammers during the dust storm. Americans rely heavily on airborne GPS and radar surveillance systems, and sadly, all GPS navigation bombs fall off their targets.
A GPS jammer is a device that jams the GPS signal and can completely block the Global Positioning System. Such jammers are not surprising in real life. It can block GPS positioning and make it disappear within an area (usually 5-20 meters).
GPS is just a very important function in a mobile phone. This makes it easier for people to navigate and gets you where you need to go quickly. At the same time, nearby retailers can pass relevant information to us. Someone recently asked if the GPS is being tracked when the phone is turned off, and whether a portable mini GPS jammer can effectively block the location.
Today, mobile phones are no longer the high-quality luxury goods that they once were, and people can buy them easily and cheaply. However, using your phone regardless of the situation can have negative consequences. For example, the noise created by using a cell phone to manage books can affect readers. Using mobile phones in the classroom not only affects learning, but also disrupts educational discipline. Even on the crosswalk, many people are looking at their phones. This is very dangerous. To stop this uncivilized and dangerous behavior, you need to use a cell phone jammer.
Mobile phones have brought us comfort and convenience, but they have also brought us many problems. Putting down the phone seems easy. Indeed, how many people can do it. Using mobile phones for a long time can lead to myopia or even deep myopia, which can seriously damage the glasses. At the same time, in addition to playing less and not making calls, you also need to know some methods to prevent mobile phone use.
Many cell phone jammers will not only interfere with cell phone signals such as GSM 3G 4G, but also GPS signal jammers, which can set the jamming frequency band to strong GPS WiFi UHFVHF signals. Radio waves are emitted, and this part of the frequency band coincides with the frequency band emitted by the jammer, making it ineffective.
We know that all our mobile phones are equipped with GPS navigation and positioning systems. If you use various applets or software on your phone, you will be asked to access your location to get your location. Unfortunately, many thieves and criminals place small GPS tracking devices in our cars and vehicles to monitor us in real time and allow them to carry out illegal activities such as car theft. .
Importantly, cell phone jammer are not only powerful, they are also inexpensive, have tunable jamming bands, and are versatile. Some specialized fields, such as military aviation, use advanced technology to reduce the effect of cell phone jammers on GPS navigation by using special antennas that only receive signals in certain directions.

What are the advantages of high-power mobile phone signal jammers?
GPS is also known as Global Positioning System. We are very familiar with GPS signals in our lives. Our cars, cell phones, and even some smartwatches have GPS positioning and navigation systems. GPS plays an important role, especially in some military fields.
Technological developments have played an important role in the further expansion of GPS technology, which is also very important for military applications. In modern electronic warfare, GPS signals are closely related to the life and death of the army and even the army. Advanced GPS satellite positioning systems and GPS signal jammers are the equivalents of powerful umbrellas and sharp arrows.
GPS signal system is also very important in our real life, such as GPS tracking, car GPS navigation, and many GPS software for mobile phones, especially GPS locators. Some detectives and criminals use GPS to track and identify us in real-time. Information seeking an improper advantage. With GPS Jammer, you can completely block your location information in real-time to protect your privacy and personal rights.
Cell phone jammers are the best products for blocking signals. Installing a signal jammer is easy. A handy jammer is an electronic device that blocks signal transmission between a cell phone and a base station. When using the same frequency as a cell phone, cell phone jammer can strongly interfere with communications between callers and receivers. Effectively block signal transmission from UMTS, 3G, CDMA, GSM, PHS.
Mobile phones use different frequency bands in different countries. The 1900 MHz band is the dominant frequency band in Germany, especially in urban areas. 850 MHz for local backup. In the US, the 850MHz and 1900MHz bands are used depending on the region. Europeans use the GSM900 and 1800 bands as the standard. These bands are also used in the Middle East, Africa, Asia and Oceania. In Russia and some other countries, local operators have licenses for the 450MHz frequency to provide CDMA coverage.
Using different frequencies makes it difficult to place jammers on all frequencies. Previously, you had to manually adjust the signal range for interference.
However, all jammers on the market today have corresponding antennas. Just buy the corresponding nuisance model and install the corresponding nuisance antenna to easily interfere.
U.S. Air Forces, warships, and allied air forces are organized into large "air strike groups" to minimize U.S. regional GPS signals near closed training areas. Fight against competitors. Advanced GPS jamming techniques are likely to be used to prepare for the worst combat without GPS support, but this has serious implications for many domestic civil aviation flights.
Military experts say the United States is training a very large army in Northeast Asia. Military equipment is very advanced, surpassing the technological level of other countries. Meanwhile, the largest red flag movement in history took place in the United States and lasted a month.
Many important facilities in our lives require GPS satellite systems to determine their orientation. A GPS outage can cause serious damage and irreparable accidents. GPS satellite positioning signals and navigation technology should be used in all countries and in all industries. When using GPS jammers, be sure to pay attention to the area of application and do not use them for criminal purposes.

What should I pay attention to when using GPS jamming?
Cell phone jammers need systematic management
Why install cell phone GPS jammers? Some students use their cell phones to text each other during exams, check their writing online, and put up shields to prevent students from cheating on their phones. Many students lie in bed when they are late for get out of class or study. There is a lot of bad information on the Internet, which is not conducive to the growth and learning of students. Some students text and phone appointments late at night before going to bed, affecting the next day.
GPS jammers are often identified as interference that may occur due to equipment defects or other unforeseen events. Interference-prone devices are subject to various regulations. Jamming occurs when an operator transmits on a busy frequency without first checking that it is busy or cannot hear the station using that frequency.
Mobile phones have become an integral part of modern life. There are more mobile phones than ever before, and this number is growing every day with the introduction of new models and types from time to time. It is estimated that there are 7.22 billion mobile phones and 7.19 billion people worldwide. Such a large number of cell phones and their prevalence means that there are a lot of unnecessary cell phones. There are several ways to handle these unwanted calls. One of the most common ways is to keep your phone on silent or vibrate. But so far, that's where cell phone jammers come into play. They provide an effective barrier
Blocking one caller at a time is cumbersome and time-consuming. However, cell phone jammers can block all incoming calls at the same time. This can be a complicated process for many people, but it's very simple. Cell phone jammers emit signals at the same frequency as cell phone signals. The jammer then sends this signal to the world. If successful, the phone will no longer receive a signal at the specific location.
There are several reasons why people choose portable jammers. For example, business owners can block employees' cell phone signals to avoid interruptions or interruptions to work during important meetings. Jammers can also prevent your phone from sending outbound messages. Humans can use jammers as a security measure to prevent sensitive information from being leaked. It is also used for stop signals to prevent terrorist attacks. Another reason I like the jammer is that it's not a "phone off" message, it's a "service interruption." This means that the caller cannot reach the phone owner.
Cell phones transmit their signals to cell towers near their location. Cell towers share the workload by focusing on specific areas. During your trip, your phone will send a signal to every tower along the way. The jammer sends radio frequencies to the same tower and covers the phone signal. The signal from the cell phone collided with the signal from the interfering device, cutting off the communication between the cell tower and the cell phone.
Some of the world's most advanced law enforcement agencies use cell phone jammer, making them reliable and convenient. They have been used successfully in many counterterrorism operations to disrupt communications between explosives and cell phones. Law enforcement agencies also use them to prevent communication between criminals. Cell phone jammers have become an important tool in government offices, assembly points, hospitals, libraries, schools and theaters where silence is also required.

A notice:
When using a car GPS jammer, you should pay attention to the following points:
1. Is the shielded antenna in good condition?
2. Whether the antenna is plugged in properly when using it.
3. Whether the interface between the antenna and the instrument is tight.
4. Whether the inserted meter is in good contact with the car cigarette lighter socket.
Mainly due to the release of radio interference waves, the GPS locator can be disabled within the specified electromagnetic band range to form the same electromagnetic environment as the device and achieve the purpose of shielding the signal.
GPS devices require a calling card. The current location information calculated by the GPS module is uploaded from the communication base station to the positioning server through the map for user query. The jammer uses the connection between the wireless electromagnetic wave jamming card and the communication base station to achieve GPS positioning, and the user cannot inquire for this purpose.
But first of all, you need to distinguish what kind of signal tracking method your car's GPS uses. Second, go to the electronics market to buy a GPS signal cellphone jammer
There are only two ways for signal tracking: (1) Cell phone signal. (2) Direct satellite tracking signal.
Generally speaking, most GPS positioning signals use mobile phone signals, and the signal is blocked, causing all communication devices within the range to lose their signals. But such a device also has drawbacks for the users who use it: the signal jammer can only be turned on temporarily, not permanently, and the GPS signal can be reused as long as the jammer is turned off.
