GPS Jamming And Its Security Benefits

.

It seems everywhere you go in life GPS jammers are a real problem. You see them on roads, on the Internet, even on some cell phones. Some are very clever and can hide their use very well, while others are very simple and only mask a signal. The common factor though is that all GPS jammers have one thing in common: they prevent GPS based navigation from being done by the people who need to get it done.

jamming and radar blocking is a form of electromagnetic countermeasure that deliberately sends out false information or radio frequency pulses to interfere with a radar or other electronic tracking system by saturating its directional receiver with false or artificially generated noise. The common practice of jamming occurs when a malicious party, such as a security guard, wants to keep a vehicle occupied or just trying to locate another vehicle, read more here. This causes a satellite signal blocker to be installed on the highway or other high powered communications links such as cell phone towers.

While GPS vehicle tracking devices were initially developed for fleet owners and law enforcement officials, this technology has expanded into everyday use and can be used by anyone wanting to monitor their car's GPS location at any time. In fact, some people who suspect their spouse of infidelity install these so-called GPS jammers to find out if they really are cheating. For fleet owners who want to know where their vehicles are at any time day or night using GPS tracking devices, this can be extremely useful.

These high-tech jamming devices were once installed as a way to protect the integrity of the GPS system itself. If a vehicle's navigation system was jacked into, it could not transmit data, thus preventing the system from working properly. Other types of GPS jammers interfere with a vehicle's ability to communicate with a vehicle tracking device, creating confusion which could cause the wrong data to be provided to the rider. Since a GPS system is used to locate a vehicle, getting data from this system may prove to be extremely important to fleet owners.

Fleet managers have a variety of options when it comes to protecting their assets. Traditional GPS devices are connected to servers maintained by a third party company which can constantly monitor the position of vehicles and can determine when an unauthorized device is installed, also discover more. The GPS jammers allow fleet managers to disable or remove any interfering devices, allowing them full access to the GPS signals. In addition, these devices often detect a weak signal and prevent other vehicles from communicating with the main GPS system.

GPS jammers can also be used to protect against theft. Many people don't like the idea of having their GPS signals detected while in motion. These small GPS jammers can be placed beneath the dash of a car to prevent theft of this type of valuable cargo. While GPS jammers are generally used by law enforcement officials and security personnel to investigate crimes, they can also prevent an intruder from breaking into a secured area to ensure the devices are left safely in place. These devices are also commonly found in private homes, to prevent the discovery of items stolen. Read more at https://en.wikipedia.org/wiki/Global_Positioning_System
