The Global Positioning System relies on precise time data being sent from 31 satellites equipped with atomic clocks in space; a receiver calculates its location by determining its precise distance from a handful of those satellites. It’s not used just for navigational purposes but also for precision timing to, for example, document market trades (time is indeed money). GPS jammer work by broadcasting noise on the same frequencies used by the satellites, so that receivers can’t pick up the signals. Depending on the broadcasting strength of the jammer, it can knock out GPS reception for a few yards or for miles.

GPS tracking technologies are on the rise as new innovations continue to be developed. With the prevalence of smartphones and IoT devices, every location, online search, visited website and purchase made is being tracked. While many people are willing to share their location for good purposes, there is another set of people who want to hide their location.

For the safety of cars, trucks, buses, vans and even ships, just plug the portable GPS jammer into any cigarette lighter or vehicle power outlet to stop the GPS tracking signal. With a coverage of up to 10 meters, you can protect you from logging in even on the largest vehicles.

The GPS jamming unit itself is typically a small, self-contained, transmitter that generates a 1575.42 Mhz interference signal over a 5 to 10 meter radius.

Military jammer are intended to deal with such threat that makes all possible privacy issues look unimportant in comparison with this global danger. I am talking about terrorist threat. The danger of ending up in the middle of a terrorist act with hand-made bombs (or like they are often called – Improvised Explosive Devices, or shortly IEDs) exploding nearby, hurting and killing people beside you. This is terrifying… But military forces made special devices to counter this threat in countries like Iraq and Afghanistan, where soldiers are exposed to IED threat every single day. Military jammers are used by all those soldiers to simply keep them alive. However, they can be also used by citizens, the only difference between them and other blockers that military blockers are very powerful and able to jam different frequencies at the same time. So it could be a great solution to use military signal jammer in your vehicle, for example, to prevent all tyes of spy tracking.

The military rf jammers have high power and range of interference, which can interfere with the ultra-high frequency signal of radio spectrum, and can interfere with very high frequency (30-300 MHZ) and high frequency (3-30 MHZ) signals.
