Glonass GPS L1 1570 - 1580 MHz GPS Signal Jammer for Car Vehicle , Portable Signal Jammer
Portable Signal Jammer Description:
GPS signal jammers 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 1 - 10 meters 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.
Why do you need a Vehicle Car GPS Jammer ?
It might be a bit mystifying to some as to why someone might want to jam a GPS signal. However, there are those with a particular need for privacy, be it to massage their paranoia, keep law enforcement from engaging in warrantless car tracking, take an unauthorized lunchbreak with a GPS enabled company car, or a teenager not wanting their parents to track their GPS phone. Whether this is all legal or not is an entirely other question.
How do Vehicle Car GPS Jammer Work ?
The basic purpose of a GPS signal jammer 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.
The GPS signal 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.
GPS signals are quite weak, being distributed out across the surface of the Earth by satellites high in orbit, so out of all the signals to jam, they're among the easiest to do so.
