GNSS Interference: Sources, Effects, Detection and Mitigation Techniques
Date: Dec. 3
Sponsored Content by: Tallysman
Summary: Today's radio frequency spectrum is crowded with cellular, Wi-Fi, Iridium and Inmarsat signals. In North America, Ligado has recently received terrestrial broadcast rights to the 1526-1536 MHz spectrum. This could cause interference that affects antennas and GNSS receivers that support L-Band correction services. Tune in to this webinar for a discussion on interference on GNSS antennas and receivers: its sources and effects, detection methods, and mitigation techniques employed by precision GNSS antennas and receivers.
Speakers:
• Julien Hautcoeur, director of GNSS product R&D, Tallysman
• Wim De Wilde, systems engineer, Septentrio
• Peter A. Iannucci, postdoctoral research fellow, Radionavigation Laboratory at The University of Texas at Austin
