A Ryanair flight from London to Vilnius had to abort its landing due to GPS signal interference, leading to an emergency diversion to Warsaw. This incident is part of a larger trend, with over 800 cases of GPS interference reported in Lithuanian airspace in recent months, raising concerns about potential jamming technology deployed by Russia. The UK government is investing in developing a secure alternative to GPS using portable atomic clocks, dubbed the 'Time Lords', to mitigate the risks associated with GPS jamming. The project aims to create a new type of optical clock that could revolutionize navigation and timekeeping, similar to historical advancements in marine navigation.
