A sustained disruption to navigation systems would cost the British economy 1 billion pounds ($1.3 billion) a day, the U.K. government said, as it outlined steps to develop its own alternative to the European Union’s Galileo satellite array.
The damage estimate takes into account a “sustained” disruption to systems that “are increasingly important for commercial, military and other critical applications,” the government said late Tuesday in a statement. The systems help guide ships, aircraft, missiles and passenger cars.
