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

Planes experiencing GPS interference due to hacking incidents prompt efforts to develop new atomic clocks that could provide a secure alternative to GPS for navigation and timekeeping. Dubbed the "Time Lords," UK scientists are working on optical clocks that are 100 times more accurate than current models to combat the threat of GPS jamming. The research aims to ensure robust and reliable timekeeping for essential services like finance, telecommunications, energy, utilities, and national security, with the ultimate goal of integrating the technology into everyday devices for widespread use.
