Re: Pulsar Nav accuracy

Hello Folks,

At present, we are using a 2 AU baseline for measurements of stars. 
Once 
we start using the ships of FT to place automated telescopes in orbit 
around the sun, we can expand the baseline easily enough.  Anyone care
to 
figure out what the accuracy will be for determining where stars *were*
if 
the baseline is now say, 40 AU's?

Also, how accurate does one's position have to be known to establish
where 
you are precisely?  In other words, if I for what ever reason, jump to
some 
unknown location in space, and I find at least 2 known pulsars -
wouldn't 
that establish the rough ball park of where I was to the extent that I
at 
least know which direction to jump back?
