An Update on GNSS Vulnerability Threats and Solutions

This presentation is an update on a larger presentation made to the Institute in 2005 by Mr John Owen. It will recap on the inherent vulnerability of GNSS signals to interference, explore the consequences of proliferation of GNSS signals at L Band and the threats from interference, both intentional and unintentional. It will conclude by examining some of the technology strands being developed to counter these interference threats.
