How public safety GIS saves us when disaster strikes
By William Tewelow
National Alliance for Public Safety GIS (NAPSG) has contributed to recovery after every major disaster and many minor ones throughout the United States. Its success extends internationally — NAPSG has helped other countries set up their own public safety GIS support teams.

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
