My COG is unusable, because it changes from GPS fix to fix, and because of the small uncertainties in the position each fix, the COG varies, sometimes even more than the 15 degrees you quote.
My Furuno navigator overcomes this by averaging the course over a selectable period. I usually set this to 60 seconds, but in some sea condition increase it to 120 seconds. I would really like to see this feature on iNavx
Even a pre-set period of one minute would be better, but being able to adjust tie period is the gold standard.
