GPS jammer. It is mainly used by commercial, military and private entities for navigation purposes. However, before starting to explain the global positioning system overhaul, we need to fully understand what GPS is.
GPS uses satellite systems and sends signals. The satellite is used in conjunction with a GPS receiver to find the position through triangulation. Triangulation is basically a technique and method that treats three different points as calculated positions. For example, in car navigation, the position is assessed by three satellites defined in orbit around the earth. Thanks to the triangulation, GPS can deliver the site to the receiver.
The GPS signal uses a specific set frequency. GPS works on two main frequencies. One is used for non-military or public use, with a frequency of 1575.42 MHz, and the other is used for military purposes, with a frequency of 1227.6 MHz. In fact, GPS relies on radio waves.
Generally, the use of GPS is very useful, such as car navigation, finding missing persons and navigating at sea. Even so, there are still many ways to abuse GPS, which is why we have GPS jammers.
The jammer makes it impossible to use the GPS function by interrupting the satellite signal. Most GPS jammers are designed for military purposes to confuse opposing military forces. GPS jammers are mainly created for military organizations, gadget companies, and government organizations.
to sum up
In the information age, the development of communication technology is very rapid.
Mobile phones have become an indispensable tool in our work and daily life.
However, the widespread use of mobile phones has also caused some major problems, most of which are as follows:
1. As a new secret leakage channel that threatens information security
With the development of science and technology, the location, tracking and monitoring of mobile phones have become the most important identification method and information source in each country. Therefore, as long as the mobile phone is carried with you, regardless of whether the mobile phone is in use, it may cause the loss of confidential information (or even in the standby state), and pose a great danger to the work unit itself or even the staff. Used in work units. Party and country.
2. As a new source of noise pollution, it will interfere with normal operation
The popularity of mobile phones has deteriorated the environment of meeting rooms, courts, libraries and schools. The noise of mobile phones disturbed the calm and serious atmosphere of these places and affected their normal functions.
3. As a new risk factor, it brings hidden dangers to the safety production of enterprises
Using mobile phones in gas stations, gas stations, oil fields or oil depots may cause fire or explosion with serious consequences.
