The Lidar-Lite looks to be an inexpensive and capable sensor. But it is new and untested by the masses in the wild. I've seen other efforts like this fall far short of claims when the real product was shipped. For that price it's worth giving it a shot. An inferred Led may just be good enough.

As to the nav6 - Invensens is now releasing their code for 9 axis sensor fusion. Up to now they only released this to their high volume partners. Fusing in the mag with these libraries may make the nav 6 way better with just a code update.

PNI corp released a new 9 sensor fusion asic this spring that has shown superior magnetic corrections with cheap mags.

Astrial navigation is do able at most venues. It does need cpu horse power.
