2. Setting Averaging Time
This navigator calculates position, ship speed and course using signals sent from GPS satellites. The
problem with this data is the dispersion introduced by
satellite location
and receiving conditions. To
average this dispersion, you can set the desired averaging time from 01 to 99 seconds.
Large values reduces dispersion. Small values increases dispersion, but you can more speedily track
the conditions of the ship.
