There are many satellites in the space, all these satellites could help us a lot in positioning, navigation and so
on. Among them is the GPS system, it makes us live easier and safer lives. But it may also cause danger to us by
exposing our positions to bad guys. A small GPS device is enough to put us in danger situation. To protect us,
we need GPS jammer. What is GPS jammer? What can it do to protect
us? First, the GPS jammer is a kind of electronic device used to block GPS signal. Once it is turned on, a
stronger signal will be issued to cover the GPS signal in the same frequency, so all GPS device in its effective
range will show no service. But when it is turned off, all GPS device will resume working in a minute, it is
really harmless to the GPS devices and other electronic devices. There are many kinds of GPS jammers, like
portable GPS jammer,desktop GPS jammer, single function GPS jammer, multi-functions jammers. Portable GPS jammer
could be carried every where, it is very small in size, use rechargeble batteries. While desktop GPS jammer use
Ac power, it is bigger in size, could be use in a fix place or in a car. An example of the use of GPS jammer is,
when a truck driver forget to bring something, he want to go home to bring it, but he don't want his company to
know this, he could use a GPS jammer to block the GPS device in his truck.
To choose a good GPS jammer(also called GPS blocker), you need to consider
the following. First, where you want to use it. If you want to use it in a fix place and you need power to be
stronger, you need to consider a desktop GPS jammer. But if you want to use it in different places, you should buy
a portable GPS jammer, which is convenient to carry but power is not so stronger as desktop GPS jammer. Second,
how big is the place where you want to use GPS jammer. Every GPS jammer has a working range, it could affect the
GPS devices in its working range only. GPS device out of the jammer's working range will woker properly. Third,
what kind of functions you want. As we know that, there are single function GPS jammers and multi-functions GPS
jammers. Single function GPS jammer could jam GPS signal only, while multi-functions GPS jammer could jammer GPS
signal and other signals, like cell phone signal, wifi signal, bluetooth signal, Rf signal, UHF/VHF signal and so
on. Different multi-functions jammer could jam two or more of these signals, customer should choose the functions
according to his actual require. Fourth, price also very important. The price of
GPS signal jammer change from tens of dollars to
thousands of dollars, customer should consider his budget before he buy the GPS jammer. For example, some cheaper
GPS jammer don't fan, it is easy to get hot, but more expensive will have fan, could make the machine cool down
and work better. Last, the law. Different countries have different rules, GSP jammer is illegal in some
countries, customer should make it clear and do according to the law of his country.
