Navigation is a universal problem whenever one needs to go from point A to point B. Around Earth's orbit, Global Navigation Satellite Systems (GNSSs) such as the American Global Positioning System (GPS) or the Russian GLObal NAvigation Satellite System (GLONASS) have revolutionized the way planes, boats, cars and pedestrians navigate. GPS did not appear overnight but was the culminating outcome of ground-based radio navigation in the 1920s, gradually complemented by satellites.

Pulsars have at least two impressive applications. First, they can be used as highly accurate clocks, comparable in stability to atomic clocks; secondly, a small subset of pulsars, millisecond X-ray (Pulsar positioning system: a quest for evidence of extraterrestrial engineering), provide all the necessary ingredients for a passive galactic positioning system. This is known in astronautics as X-ray pulsar-based navigation (XNAV). XNAV is comparable to GPS, except that it operates on a galactic scale
