Not to burst anyone's bubble, but I do not think there will be any cel nav on Mars. Why would there be? People will need a satilite to radio commumate with earth - why not use the ( many ) satilites that will be around Mars for position finding? INS would be a better opition than cel nav..
But really, a sextant? No oceans - no boats. Like others have said, a transit would be better on dry Mars land.
It would be fun for the computer programing folk to get a Mars almanac and sight reduction tables to play with.
