    Technology and real science finally catch up to science fiction again.

    It would be great if they could get the whole system to work with a small array of simple cheap tiny CCD cameras and a good processor.

    atomic time clock accuracy in deep space, indeed it would be a natural gps system!

  • Didn’t you have a recent post on the unexpected variability of some pulsars?

  • Yes, but the pulsars that suddenly change their rotation rate are rare, unusual, and easy to spot. The pulsars that would be used for this interstellar GPS technique are the more common variety pulsars, remarkably reliable and precise in their pulses.

    Not to suggest that any pulsar is common. No matter what, these are very strange beasts in the zoo of interstellar objects out there.
