Doing 64 bit floating point on a '51 would need to run overnight to complete.

Well, yeah. The OP didn't state that he wanted the calculation done fast, just that he wanted it done. If he can wait half an eternity (20 seconds is an eternity for a uC) for his result ...

However, it would be interesting where the longitude and latitude data comes from that is so accurate. I don't think regular GPS has 10 cm accuracy. Differential GPS, maybe ?
