Most GPS engines are running faster than the display rate. GPS

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?

Oh, never mind. That's what you *said*. Sorry for the noise. Dave
