A Reconfigurable RF Front-end System for GPS Anti-jamming

Abstract

Global Positioning System (GPS) signals are vulnerable to jamming signal. The jamming signal is simple and effective way to threaten the GPS system. Also, the development of drone technique makes GPS system take into account jamming attacks in the air as well as on the ground. Therefore, RF front-end system composed of multiple antenna and reconfigurable feeder is proposed in this paper to avoid jamming signal and receive multiple satellite signals.
