Most GPS engines are running faster than the display rate. GPS
engines from 5-10 years ago operated on 1 or 2 sec position updates.
Newer engines are more granular, with 5Hz operation being common.
That means the display data shown is typically derived from the
velocity/heading calculated from the time 1 and 1.2 seconds in the
past.

What units have a 5Hz update? The only one I am aware of is the CNX80. I don't
know of any others better than 1 Hz... oh, maybe you meant 5 Hz intenally, with
a 1 Hz update of the display?
