Pulsars can be used for autonomous spacecraft navigation by obtaining position and direction in space with an accuracy of 2km, on condition the spacecraft is provided by one small X-ray telescope on board.
"New method operates autonomously, increasing the number and capabilities of space missions", according to a news page from University of Leicester. |

Re orientation and position: I'd guess, that x-ray telesecopes will tend to have a narrow fov, and few valid x-ray sources (?). So, in order to be able to observe the pulsed x-ray sources for obtaining position data, they'll likely still need additional star trackers to recover orientation.
