Navigation for Spaceships Using X-ray Pulsars: Introducing XNAV

Written by Ian O'Neill

This could be the ultimate galactic GPS system: using pulsars as an 
interstellar navigation tool. Rapidly spinning neutron stars emit focused 
beams of X-rays into space and many, with accuracy as good as an atomic 
clock, have been mapped by astronomers.
