Mostly, commercial, military entities, and individuals utilize it for the navigational purposes. But before we begin to explain review the global positioning system, we need to fully understand what a GPS is portable jammer.

GPS utilizes the satellite system and sends signals. The satellite works with GPS receivers to find out positioning through triangulation. Triangulation is basically a technique and method in which three different points are being considered for computing location. For instance, in cars navigation, the location is being evaluated by three definite satellites revolving the earth. By means of triangulation, global positioning system can deliver the site to the recipient.

GPS signals make use of a definite and specific frequency. GPS works at two main frequencies. The one is intended for non-military or public use at 1575.42 MHz and the other one is meant for military purpose at 1227.6 MHz. Actually, GPS is based on radio waves.

Overall, using the GPS can be very useful, such as car navigation, finding missing persons and navigating in the sea. Even so, there are many different ways to misuse the GPS, and that is why we have the GPS jammers.

The GPS jammers work by interrupting the signals that come from the satellite and make it impossible for a device to operate. GPS jammers are being created mainly for military organizations, gadget companies and the government organizations.
