These are devices that are used to jam signals from GPS devices. The GPS devices are very useful as they help to find out the position of a car and guide it to proper destination. But sometimes signals from these devices need to be jammed for security reasons.
GPS is the abbreviation for Global Positioning System. This system is used widely in various setups whether military, commercial or individual. This mechanism uses 24 satellites revolving round the earth and issues radio signals. The device is an extremely handy gadget that can be carried by individuals, or integrated in the navigational systems of car or boat. There are also units designed for commercial and military use.
GPS works on the principle of triangulation. This is the mechanism in which three points are measured to find out the location of a car. For instance a cars location is calculated through three specific satellites orbiting the earth. Now, GPS radio signals have a specific frequency. There are two different set of frequencies for a GPS signal. One is for public or non-military use (1575.42 MHz) and one that is used solely for the US military (1227.6 MHz). Thus GPS is ultimately a set of radio waves and these waves can be jammed through a technical device called GPS jammer.
GPS jammers are very easy to install. All you have to do is plug it in your car. The advanced ones among GPS jammers can block signals that range between 1450 to 1600 mega hertz. GPS jammers are now also being used by the federal government, law enforcement agencies and the military organization in jamming signals of GPS devices belonging to terrorists and criminals. These devices are often used by the defense forces to baffle terrorists about their locations in any critical mission. The device can veer away guided missiles and bombs from their path. The GPS jammer can also work as a GSM jammer.
Besides the military establishment GPS jammer is also being used in the civilian establishments like movie halls, libraries, shrines, and other public places for security reasons. It is also used by the truck drivers to prevent unnecessary surveillance by the truck owners.
However, in many nations of the world the use of a GPS jammer is completely prohibited. This is because the device provides scope for misuse. It can confuse aircraft and other vehicle instruments that might lead to severe accidents. Therefore GPS jammers come in various categories. There certain GPS jammers that are only for civilian use. There are others that are used by the military establishments.
If you are planning to buy a GPS jammer, then buying it from the online stores is a good idea. This is because there are virtual stores that have very competitive prices for the device and also offers discounts at most times of the year. But before buying a GPS jammer you will need to agree to certain terms and conditions.
