GPS anti-tracking service
The GPS jammer works by sending out its own signal on the same frequency as the GPS unit, a noisy signal that prevents it from receiving or transmitting any useful information. There are a number of types of noise signals it can send; some call for a narrowband Gaussian signal, others for a simple continuous wave. The basic principle is that the GPS signal cannot be transmitted normally by canceling or covering the GPS signal. The basic purpose of a GPS anti tracking service is to prevent GPS loggers from either receiving satellite signals, or sending signals back to their base station. Now, chances are, any GPS you will have contact with use the radio frequency set aside from civilian use: military units use a very different frequency. GPS block service come in a variety of designs, each suited for slightly different uses. The first, and most popular model to hit the mainstream market was one that plugs into the cigarette lighter of a car, effectively disrupting the signal for a 15 foot radius. Not enough to disrupt signals from other cars, but enough to keep you in a cone of GPS jamming silence. However, other versions that are battery powered and are effective to different distances, are also available.
