On Earth, the cardinal directions are straightforward. The arrow on a compass points to the nearest magnetic pole. You can then use it to travel anywhere on Earth.
In space, the idea of anything being “central” enough to be used as a “North” (since the universe has no center) or being fixated enough to not somehow pose issues is more convoluted.
If you were a pioneer of space exploration, what would your “North” be?
Up. North on a map is always up.
You’re in a random spot somewhere in the universe. Where’s “up”?
Over there.

Opposite from the enemy’s gate.
Jump. The direction you fall is down. Up is the other way.
