Is it possible to navigate in space??

Me and a mate were out on a tramp and decided to try come up for a way to navigate space. A way that could somewhat be compered to a compass of some sort, like no matter where you are in the universe it could apply. 

 Because there's no up down left right in space. There's also no fixed object or fixed anything to my knowledge to have some sort of centre point. Is a system like this even possible or how do they do it nowadays?

Within the Milky Way galaxy, position can be computed relative to known pulsars.  Once you have your position, navigation becomes a matter of doing the same for your destination, relative to those same pulsars and yourself.
