The Gps s Power
From EjWiki
With more and more citizens arming themselves against an increasingly intrusive world the demand for video equipment and listening devices as well as personal security items (pepper spray, etc.) is growing daily.
Some of the functions include radio frequency jammers that prevent wireless spy cams from working to GPS jammers that prevent any GPS trackers from following you to cell phone jammers that stop important meetings from being interrupted by personal calls there is a jammer for every purpose.
Since GPS has always been mainly used by the military to locate the position and movement of enemy aircraft and to detect any unauthorized entry of aircraft etc in to home territory, use of GPS jammers has been restricted for the public. Well, the civilian GPS signal jammers do have different radiofrequencies than the military used ones, but there are still many countries who are not exactly comfortable with the idea of widespread use of GPS jammers by the civilians.
The US military has raised concerns, even though the military and commercial GPS functions at different radio frequencies when compared to the civilian use. This is because these receivers used by the government actually at first require getting the C/A signal (civilian) before they can proceed to get the military used P(Y) signal. So in case you are planning to buy a GPS jammer, it would be better to check with the local laws first, to avoid running in to trouble later on.
Even more, Qatar asked for 24 AH-64D Apache Attack Helicopters
which are also in the pipeline for sale. That sale includes nearly 600 Hellfire missiles and 300 stinger missiles, as well as night vision goggles, 60 GPS systems, 30 radio jammers, 30 chain guns, and much more.
The Wall Street Journal broke the story
the other day that the United States will be building a missile defense radar station at a top secret site in Qatar. While that's been widely reported, there have been a recent bout of proposed foreign military sales to Qatar that have been largely under-reported.
If you want to get a GPS jammer for yourself, then it is very easy and cheap. Just buy a good one from one of the numerous online stores. But as mentioned earlier, it is better to check your local laws, because you would not want to have a rough time with the law enforcement folks after you get the GPS jammer shipped to your place.
GPS is the symbol for the Global Positioning System. It is a satellite navigation system designed and built by the United States Department of Defense. It was first conceived in the 1960's and the first GPS satellite was launched in 1978. This navigation system became fully operational in 1995 and was used exclusively by the U.S. Military until the U.S. government authorized its use by the general public.
The 24 satellites orbit the earth in 6 distinct trajectories. They orbit the earth twice a day at around 7,000 miles per hour at a distance of 12,000 miles. This allows their signals to be received over a large percentage of the earth's surface. The more satellite signals a GPS unit receives the more accurately it can calculate In the event you loved this post and you want to receive more information relating to Insert Your Data assure visit our own web page. its position by triangulating the signals. The satellites orbits are placed so that nearly every part of the earth is receiving 4 signals at all times. Of course landscape and groundcover can affect this.
While it can be argued that pen lasers are used for presentations and can do little damage there are lasers out there that can do more than show a spot on the wall. To that respect lasers above a certain mW strength are authorized for government use only and will be seized if caught in the hands of a 'civilian'.
Jamming devices are also regularly featured in spy and action pictures. Dependent on the scene, heroes or villains would simply flick a switch on a device or console to prevent their adversaries from making a call, activating another device or triggering a bomb. On other scenes, jammers are used to interrupt radio and other communication signals as well as rendering radar and other direction systems. People would be surprised to know that the spy gadgets they see in these flicks are available commercially at the moment.
While GPS jamming devices are manufactured to be effective against civil use GPS signals only (C/A code) the prevailing sentiment is that use of these devices may interfere with public transportation and military frequencies.
The portable GPS signal jammer creates a safety area of around 10 meters around the device, and this particular area is safe from the probing GPS signals. 10 meters is more than enough to cover a human or even a large vehicle, so portable GPS jammers are handy enough and allow you and your vehicle to move without getting in to the GPS monitoring.
Other items you need to consider before purchasing signal jammers is the power and working coverage area where the jamming frequencies are going to be used. Transportable and pocket-sized versions are enough to cover a room, but you'll need stronger devices if you need to cover a larger area or even an entire building.
