  title={Autonomous Spacecraft Navigation With Pulsars},
  author={Werner Becker and Mike Georg Bernhardt and Axel Jessner},
  journal={arXiv: High Energy Astrophysical Phenomena},
An external reference system suitable for deep space navigation can be defined by fast spinning and strongly magnetized neutron stars, called pulsars. Their beamed periodic signals have timing stabilities comparable to atomic clocks and provide characteristic temporal signatures that can be used as natural navigation beacons, quite similar to the use of GPS satellites for navigation on Earth. By comparing pulse arrival times measured on-board a spacecraft with predicted pulse arrivals at a… Expand
