Global navigation satellite system technology (GNSS) is currently the most prevalent used for global precise Position, Navigation and Timing (PNT). However, traditional GNSS is vulnerable to jamming and spoofing attacks, and threats to traditional GNSS are multiplying dramatically in recent years. In this webinar we will discuss precision terrestrial Time, and Position and Navigation derived from current and potential future LEO constellations using Navigation Signals and/or Signals of Opportunity.
