I think the centre of the galaxy would be a good idea, if only as it
will simplify the Maths! If we said that Earth was (0,0,0) then the
x,y and z axes would be moving all the time. For one season the Sun is at
(1,0,1) and the next it's at (-1,0,1). Having said that, it might
help if we always considered the sun to be at the origin (0,0,0) and
the x axis always points to the Earth. Except the whole universe then
starts rotating at one revolution per year?

I've just tried it and it's hard work. Just put the name of the
place you want to go into a computer and let it work out the route for you!
Just a thought.

It's too detailed for the discussion at hand, but I was wondering if it
would be practical to use several systems. For interstellar travel, use
galactic coordinates. For in-system travel, use solar coordinates. On a
planet's surface, use the local latitude/longitude. Basically, use the
nearest large gravity well as a reference point. ;)
