I'm wondering if the terrestrial GPS constellation might not be useable for triangulating your position on the way to the moon. Suppose that a few times each day, four of the little fellars turned themselves towards the moon so that the CEV could get a fix. Granted, it wouldn't be your typical GPS receiver, but the principals should still apply after a few coordinate transformations - I think... Would that be more or less accurate than a stellar triangulation?
