Pulsars Could Cut Out The Middle Man For Interstellar Travel

Is it feasible to use dead stars to navigate spacecraft in deep space? Long-term space travel may be a pipe dream outside science fiction math but people inside science are at least thinking about how to make navigation possible. 

Spacecraft navigation currently relies on radio transmissions between the craft and a network of ground-stations on Earth. This means that the craft has to wait for an instruction from Earth to guide it through space and with the large distances involved this could take hours, days or even longer - not really practical if we are going to Alpha Centauri. Even for unmanned ships going to closer areas, that time delay affects a spacecraft's ability to react rapidly according to its location, and ground infrastructure becomes increasingly difficult and expensive to maintain due to the size of radio antennas.
