Do you have some power or size limitation?  If not you can do a lot
better than 1 second per year.  But if it has to run for a year
non-stop and fit in a pocket, well then it s a hard problem.

I think if you could state the space, power and cost budget some one
could suggest something.

And then sample handheld GPS will always give you the best results.
But that's cheating.
