This article will explain 3 different types of effect GPS Jammer devices that can render you invisible to GPS Tracking devices.

But the question is what do these GPS Jammers look like and what are the best ones to get. We explain the models and the differences between them. Bear in mind, these GPS Jammers may not be legal in all countries.

But first, we explain a little about GPS Jamming in general.

GPS receivers rely on signals from four or more visible satellites in a constellation of orbits at distances of more than 13,000 miles. “The distance and power of the constellation signal is the chief weakness of GPS, that is, jamming or spoofing of the low-power signal,” says Murray Rosen, Technical Director of New Jersey-based Electro-Radiation Inc. (ERI).

Model 001 Coverage:4~6Meters

For Car Security, C.T.S brings you this Anti GPS Tracking Gadget, with an incredible 3-6 meter coverage. It is very easy to use as all that you need is a standard cigarette lighter with 12V for power, and the GPS Jammer will automatically cut any GPS Tracking on and within your Car. A nice item to own, and comes with a one year warranty, so feel safe ordering Chinavasions Car GPS Jammer.

003 Model

A GPS-Jammer is a jammer for the signals of the global Positioning system (GPS),  a system to the worldwide determination of the position, the gets carried on from the Department of Defense of the USA.

By the relative mean transmission power of the satellites, the orbit in height of ca. 19 500 kilometers over the earth and the small Effizienz of the aerials of the GPS- addresses on the earth, are the PS-signals only to receive with an avowed small field strength.

Already disturbing signal with very lower field strength can the reception cover over of the satellites. An additional modulation  of a interfering transmitter can occasionally the GPS-reception or also complete stop.

The GPS Blockers can be purchased at www.thespystore.com but the downside is that the FCC is cracking down on these along with cell phone blockers for obvious security reasons.
