Abstract

The Global Positioning System (GPS) is the oldest and the most-used navigation system in the world due to its manifold and diverse applications. But it has several drawbacks in terms of accuracy and interference as well. At a later stage, Global Navigation Satellite System (GLONASS) was developed to address these problems but it could not live up to the expectations as well. The most recent as well as advanced development was made in the year 2016 in the form of Galileo GNSS. It is said to be the youngest satellite navigation system which possesses a higher tracking accuracy and speed than both of GPS and GLONASS. This paper makes an attempt to implement the chirp jamming in order to jam the acquire signal, followed by anti-jamming using NLMS algorithm of the Galileo GNSS to retrieve back the original signal, which is till now lacking in the existing literature for navigation systems.
