Planes are having their GPS hacked. Could new clocks keep them safe?

The article discusses the threat of GPS hacking and the potential solution of using new atomic clocks to protect aircraft navigation systems. It highlights the growing concern over cyber attacks targeting the GPS systems that planes rely on for navigation and guidance. The article explains that GPS signals can be spoofed or jammed, leading to false positioning information that could have catastrophic consequences for aircraft. To address this issue, researchers are exploring the use of advanced atomic clocks as an alternative to GPS. These atomic clocks are highly accurate and could provide a reliable backup system in the event of GPS disruption. The article notes that the increased precision and stability of atomic clocks could help planes maintain their position and course, even if the GPS signal is compromised. The article suggests that the implementation of these new clocks could be a crucial step in safeguarding the aviation industry against GPS-based cyber attacks, ensuring the continued safety and reliability of air travel.
