Co-Site Interference Modelling, Characterizing and Mitigation Between Inmarsat FB and GPS Systems Onboard a Submarine

This paper focuses on modelling and studying the RF interference (RFI) between a civilian Inmarsat FB emitter at 1627 MHz (culprit) and a GPS L1 band maritime system at 1575 MHz (victim) on close antennas proximity onboard a submarine. Once detected the RFI, we propose the design of an adequate mitigation for it.
