Different categorization for jammer: The enemy of satellite navigation

Abstract

We are leaving in the world where rapid changes in technologies are taking place. The world is not the same what it was before 20 years. With new technologies every new day, mankind have achieved tremendous amount of dreams which were almost impossible few decades back. Automatic cars, auto navigating planes, goods delivering drones and many more are the dreams going to complete in near future. Navigation signals will play key role for the development of this technologies. At the same time a group of people having destructive mind have developed the jammer and spoofers which can affect the navigation signals. It worsens the navigation system. It may totally lose the navigation signals or may feed the wrong navigation signals to mislead the system. These things are being proved as a bigger challenge to the upcoming technologies. To fight with this enemy detailed study of jammers and spoofers are required. In this paper jammers are categorized using different ways to understand its signal property. After proper knowledge of these signals one can develop a system which will be immune to the jamming signals. Here, the classifications are done with the detail signal characteristics of jammer, are more beneficial to develop reinforce navigation signal receiver.
