About this talk
Critical systems rely on GPS for precise timing. Without it, synchronization fails, leading to widespread disruption. Understand the hidden vulnerabilities. #GpsFailure #SystemSynchronization #TimingServices #CriticalInfrastructure

And then we have position, navigation, and timing services. So, GNSS, GPS, very well known, again used by by almost everyone, but again, very critical. Uh if it fails, a lot of systems fail that are based on it. Often, you don't know that these systems are actually using, for example, GPS to to synchronize the timing. So, they use GPS for retrieving timing information from the signal as an external source because maybe you don't have an atomic clock in your infrastructure. But if the GPS fails, you you are in in real trouble. Um because systems cannot sync anymore.
