An Empirical Performance Study of IRNSS S-band Signals under Bluetooth Interference

Indian Regional Navigation Satellite System operates on L-band and S-band frequencies [1]. The S-band spectrum is congested with several other signals including the signals operating in the license free band. IRNSS S-band signals are therefore more vulnerable to Radio Frequency Interference (RFI) from various terrestrial S-band sources like Wi-Fi and Bluetooth [2]. This paper investigates IRNSS S-band signal performance in the presence of terrestrial Bluetooth signals.
