On course we have had distributed clocks for centuries now.  They keep
getting better but those clocks in the GPS satellites are not nearly good
enough to detect gravity waves.  To do that I think you need about 1E-16 in
the short term.   This is way past what anyone can fly in space in the
reasonably near term future.

But if you had such clocks you could detect all kinds of things from
minerals underground to black holes in space.  But today GPS is not close
to being able to see these tiny effects.  Maybe in the next century?
