As the GPS system becomes more and more popular, the GPS jammer also becomes necessary for us. You may wonder what the GPS jammer is and what potential applications they have. To explain the GPS Jammer, we first need to know how the GPS system works. The Global Positioning System — GPS for short, is a system used by many peoples, companies and armies for navigation purposes. The GPS system uses a series of satellites transmitting radio signals. This type of signal reaches a GPS electronic receiver to determine positioning through a form of triangulation. GPS could be used in individual portable electronic devices, navigation and vehicle positioning systems, also in small GPS tracking devices. An individual’s position can be discovered by triangulation, a method that measures three separate points to calculate a location. In a vehicle’s GPS system, the location of a car is measured by three satellites orbiting the earth. The GPS can deliver the location to the receiver with an accuracy of only a few centimeters with the use of triangulation.
Now let’s take a look at GPS signals, which are radio signals occupying a specific frequency. There are actually two major frequencies that the GPS works on, one of which is for public, non-military use and the other is used only for the United States military. Since GPS is nothing more than weak radio waves, these waves can be blocked or distorted using a GPS jammer, although technical devices and expertise are required for this purpose.
GPS jammers were originally created by the government, for military organizations and spy agencies. Some of them can be combined with the cell phone signal jammer — also called the cell phone jammer, and the wifi jammer. Uses include confusing the enemy at exact locations, or where enemy GPS-guided missiles or bombs will fall.
Recently, civilians have sought these devices to protect their privacy in a world increasingly monitored by GPS. However, most civilians do not have the technical capabilities to create their own device, as it is a little more complex than blocking a radio signal with basic radio interference.
There are a few civilian uses for interfering with GPS signals, primarily related to privacy, including the ability to conceal yourself or your vehicle in case it is tracked by a GPS receiver. A practical application would be a seller or delivery driver, who may wish to have lunch outside his territory, or return home for a forgotten item, without having to do a lot of explanations due to the GPS tracking on their vehicle . The range of most civilian GPS jammers is enough to cover even the largest of vehicles, giving the user a cloak of privacy.
Another use of the GPS jammer is to hide our places from being tracked down by the bad guys, so that we can protect ourselves and our family.
