Interplanetary Navigation with X-ray Pulsars

A Technology Demonstration Experiment

ISRO HQ - 22 Apr 2014

“The knowledge of how to use stars, planets and stellar constellations for navigation was fundamental for mankind in discovering new continents and subduing living space in ancient times. It is fascinating to see how history repeats itself in that a special population of stars may play again a fundamental role in the future of mankind by providing a reference for navigating their spaceships through the Universe.”
