Yea,the solution is to have a dedicated port for corrections, you could use a module on the third port…
As for the dynamics, I also confirm that the fix is lost during even slight changes of direction…
(IMHO) Quectel did not implement a motion variile because the kisilicon chip (LG290P) was not designed to process hight motion dynamics;(perhaps deliberately by the creator so as not to allow for military purposes).
