GPS is the abbreviated form for Global Positioning System. This device is used for helping in navigation. It is generally used by military personals but nowadays even individuals are using it to help them when they travel to unknown places. There are around twenty four satellites that revolve around the earth and launch radio signals. These satellites support the GPS systems to work and provide information for navigational purpose. The latest versions of GPS are used in cars, boats, highly specific commercial goods and in various military equipments.
The basic principle behind the working of a GPS is the triangulation system. In this system, three points are taken and distances from these points are calculated to figure out the exact location of that place. The location given by GPS is very precise and is as close as a few centimeters to the exact location. A GPS works on radio signals. There are two radio signals which are used by a GPS, one signal is for the use of civilians and the other is used by the military of the US. The GPS can be easily jammed with help of a GPS jammer because radio signals are very easy to block.
This GPS jammer finds application in various areas. A GPS jammer is generally created by government agencies, military agencies or other intelligence agencies. It is beyond the scope of an individual to construct a GPS jammer at home as there are many technicalities related with GPS signals. GPS jammer used by military is for the purpose of confusing the enemy. These jammers mislead the enemy regarding their present location and the location for the bomb and missile targets. As for the civilians, a GPS jammer is used to mislead any GPS which is tracking a car or any such thing.
These jammers are banned in many countries; one can not construct or use this device as it has an enormous scope for causing damage. A GPS is used by many vehicles such as aircrafts and warships and the use of any such jammer can confuse these vehicles and cause a lot of damage. There are special jammers made for the non-military use and do not interfere with the military frequencies.
There are Wi-Fi jammers also that have the capability to block the Wi-Fi signals. These are specially designed jammers that come in very compact sizes and can be easily accommodated inside a pocket or a handbag. A jammer used for Wi-Fi signals prevents two electronic devices from communicating with each other. It prevents any sort of incoming data to reach its intended receiver.
It is very difficult to buy a jammer that can disrupt GPS and Wi-Fi services. There are lots of websites which claim to sell such jammers, but it is very important to very carefully check for the credibility and the authenticity of such websites and their products. Possession of any such device which is otherwise banned in the country can put you in great trouble and such web sites can be fake and loot your money.
