We’ve seen some remarkable feats of celestial navigation lately, not the least of which has been the flyby of comet Hartley 2 by the EPOXI mission. But as we continue our push out into the Solar System, we’re going to run into the natural limits of our navigation methods. The Deep Space Network can track a spacecraft from the ground and achieve the kind of phenomenal accuracy that can thread a Cassini probe through a gap in the rings of Saturn. But positional errors grow with distance, and can mount up to 4 kilometers per AU of distance from the Earth

That means if your trying to land on a planet in the Andromeda Galaxy, you're gonna miss.... Of course, by the time anything we sent got there, we'd all be dead anyway, so it won't matter to us. lol
Real men don’t need maps.
Well, then,would that necessate the naming of the spacetime zone identifying the pulsar you are navigating from, eg standard B1913+16.
Unless it is not necessary to use other pulsars being one could cover so broad an area of space it won’t be necessary.
What about measured time itself, (clock time). Independant from Earth and without the relation of sun to it, would they also create a different method of keeping time? Pulsar clock time?
You are forgetting Relativity. The faster you go, the slower time advances.
“You are forgetting Relativity. The faster you go, the slower time advances.”
So they’ll refer to earthtime?
I can’t quite remember. I had a course in Special Relativity about 30 years ago. A one month, one credit course.
Bet it feels like a lifetime ago...
(Thank you, I'll be here all week...)
Every thing else just seems to fly by.
I TOLD you to ask for directions back there, but noooooo, real aliens don't ask for directions. So, how many parsecs has it been since we've seen a dilithium station Mr. Smartypants???
EXCELLENT !!!
