Selective Suppression of IRNSS S-band Signals for Specific Applications
The Indian Regional Navigational Satellite System (IRNSS) has become operational recently. IRNSS S-band signals are more vulnerable to Radio Frequency Interference (RFI) as the S-band spectrum is congested with several other signals including the signals operating in the license free band. It operates in L5 and Sl frequencies. The performance of IRNSS receivers meant for non-precision applications can be enhanced by suppressing Sl signals. In view of this, an aluminium reflector is designed and developed to selectively suppress Sl signals. The results are encouraging.
