Position Smoothing

When the DOP or receiving condition is

0-999 seconds

 

unfavorable, the GPS fix may change

 

 

greatly, even if the vessel is not moving.

 

 

This change can be reduced by smoothing

 

 

the raw GPS fixes. A setting between 000

 

 

to 999 is available. The higher the setting

 

 

the more smoothed the raw data. If the

 

 

setting is too high, the response time

 

 

required to show a change of latitude and

 

 

longitude will be too long. This is

 

 

especially noticeable if the vessel is

 

 

moving fast. Increase the setting if the

 

 

GPS fix changes randomly.

 

Spd/Cse Smoothing

During position fixing, ship’s velocity

0-999 seconds

 

(speed and course) is directly measured

 

 

by receiving GPS satellite signals. The raw

 

 

velocity data may vary too much

 

 

depending on receiving conditions and

 

 

other factors. You can reduce this random

 

 

variance by increasing the smoothing. The

 

 

higher the smoothing setting, the more the

 

 

raw data will be averaged. If this setting is

 

 

high, the response to speed and course

 

 

changes will slow. For no smoothing, enter

 

 

all zeroes.
