Using timed pulses from fixed known points to determin your position. Am
I
talking about pulsars or GPS? I could see spaceships using pulsars as a
stellar GPS system being able to locate their position faster and more
acuratly that even a GPS system (after all, pulsars are used to
calibrate
atomic clocks).

Hurra for pulsars, gods celestial timepieces.
