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. |

Well, the pulses aren't sinus-like, but very short and intense. This results in an accurate time resolution. The time between the peaks can be interpolated by a clock.
More pulsars tend to reduce statistical errors or outliers, yes. |
