Thanks for the link Luc.
I see that Sam observed the Moon and got to within 9' of GPS. He was satisfied but I think he probably did better than that. It would be of interest to look at the data for that Moon shot if Sam is watching.

The navigation bit starts 24 minutes into the second episode: http://www.dailymotion.com/video/x2f1pxg He's got a pole with him, too. Luc
