[time-nuts] Best Chance GPS module

[Mark Sims]

The Trimble timing receivers have a "single satellite" operating mode that says to only use the highest elevation satellite that it sees (or you can set a specific single satellite to track).   It would be interesting to see how the performance compares to its standard "overdetermined clock" mode.  It might help in situations where you have a poor sky view.  

The Trimble devices tend to jump around quite a bit whenever the tracked satellites it is using changes.  Having an accurate position helps minimize the jumps.
