It's an interesting problem. Could you just use a camera, and photograph some different peaks at one location and then walk a little way and photograph those same peaks and use some software to know how far you moved? You're in a crater so the crater rim should be visible from most locations. I'm sure they want to photograph everything anyway. So they just need software. No bread crumbs or thread to carry.
