The use of GPS jammer and the working principle of GPS
GPS stands for Global Positioning System, a system used by individuals, commercial entities, and the military, primarily for navigation purposes. If you want to buy a GPS jammers, you can have a certain understanding of its function, that is, jamming the GPS signal, which can prevent GPS tracking.
GPS The global positioning system uses many orbiting satellites that emit radio signals. The signal reaches the GPS receiver to determine the position by triangulation. GPS can be found in personal handheld devices and cell phones, vehicle navigation and positioning systems, and small GPS tracking devices.
A location can be found by triangulation, a method of measuring three discrete points to calculate a location. In a vehicle's navigation system, the vehicle's position is measured by three surrounding satellites. Through triangulation, GPS can transmit the position to the receiver with inch accuracy.
A GPS signal is a radio signal with a specific frequency. GPS actually has two primary frequencies, one for the public, non-military (1575.42 MHz) and one for the U.S. military (1227.6 MHz). Since GPS is only weak radio waves, GPS jammers can be used to jam or distort these waves.
GPS jammers were originally created by spy agencies, governments, and military organizations. Its uses include confusing the exact location of an enemy or where an enemy GPS missile or bomb will drop.
Now, the masses are looking for these devices to protect their privacy in the ever-expanding world of GPS tracking. There are several civilian uses for blocking GPS signals, mostly related to privacy, including the ability to hide yourself or your vehicle while being tracked by a GPS receiver. A handy app for salespeople or drivers who might want to grab something outside their workplace, have lunch, or get home without having to explain a lot about GPS tracking on the vehicle. Most civilian GPS jammers are sufficient to cover the largest vehicles and can protect the user's whereabouts.
