 OK, mind blowing: A researcher at the Observatoire de Paris, mainly for interstellar travelers invented GPS: just tune in the radio signals from four pulsars, crunch some numbers in connection with relativity (natch) and read your position within the galaxy, at - - a meter. It is logical. GPS is, after all, a system of satellite pulses of radio signals, which are triangulated by a receiver, which is close to the same land, account for about relativity. As the GPS satellites, pulsars are known places, and as satellites, pulsar pulse (hence the name), known at regular intervals, measured in milliseconds. Bertolomé Coll and his partner Albert Tarantola determined that the zero point of the theory of pulsar positioning system would be midnight on 1 January 2001, on behalf of titillatingly Interplanetary Scintillation Array in the United Kingdom, a tribute, since this is the first radio - telescope choose pulsars. Once you have checked out the zero point, the spacecraft will undergo its place in space and time, and possibly how to avoid the star or asteroid fields in this cursed hyperspace jump.
