What systems were used onboard Buran to determine its position during reentry and landing?

Since Buran has managed to return without crew on board, I assume computers had to know its position relatively accurately as it approached the runway for landing. How was this achieved?

Might either the Buran or the Space Shuttle fly again, or similar spacecraft be built in the future?

I'm really impressed with these two spaceplanes, so I'm thinking is there any chance to fly again, or some similar spaceplanes (similar design, size...) to be built?
