The 47 knew the Ark was on the ground because Miller, Jasper, Monty and Harper broke into Dante's office and hacked his computer and saw pictures of the Ark and its residence. However, Miller did not know that his Dad was among the survivors.

Anyway, that was a nice reunion between the two. I hope we get to see them more in season 3. I think Bellamy will rely on Miller more next season since Clarke is gone and Jasper's still pissed off.
