You can use GPS signal jammer and still make calls for emergencies

　　Most of us use cell phones and take them with us everywhere we go. GPS stands for Global Positioning System. It is important to know that GPS systems are located in our cell phones.

　　This could be a good thing if we get lost but if we do not want to have our privacy breached it could be bad. This means that by a method of using three points of geography, called triangulation, our location at any time can be found.

　　It may sound scientific but satellites orbiting the earth are used to help with these pinpoint locations. GPS works all by using satellite radio signals. Many cars now have GPS navigation systems that use this technology.

　　It can be convenient when taking a road trip or finding the shortest route to a destination. It is also good when you get lost and need to find an alternate path to where you need to go.

　　If GPS navigation is so helpful, why do people want a GPS scrambler or any type of GPS jamming gadgets? While there are some good reasons for GPS signal jammers, some people misuse the technology.

　　There have been cases of truck drivers using these to keep fleet management at bay. Many truck driving companies use GPS systems to monitor the behavior of their drivers and track their locations. If a driver does not want to get tracked, he may use a GPS jamming device to prevent it.

　　Some people find that they have purchased a car that has GPS monitoring and they do not trust it. It can be hard to find and disconnect so sometimes they buy a GPS jammer to combat the monitor.

　　Many of us want our privacy. A GPS jammer helps block out unwanted detection of where you are at any given time.
