X-ray ‘GPS’ unveiled by NASA

With GPS it's harder than ever to get lost here on Earth, but deep space is a different story. Mind-boggling distances, three-dimensional travel and a lack of obvious landmarks all complicate spacecraft navigation. Pulsars have been proposed as a solution in the past, and now a NASA team has demonstrated the viability of the idea, with an experiment showing that a spacecraft can constantly and automatically calculate its position by tracking the perfectly-predictable X-ray signals from an array of pulsars...
