Hi
The data is as accurate as the TBolt it’s self. The device can use the extra
digits. The utility of a more accurate position has been verified in the past.
Simple math:
Each meter you are off is 3 ns. In a worst case situation you could get 6 ns of
“ripple” as the constellation moved around you. That’s about half of the best
case day / night ionosphere shift.
