DIfferent course and heading in OpenRTK330 - for marine applications

Question about using OpenRTK330 in marine business:

Does the system assume that moving object can have some drag ? ( meaning that object course is different then heading)


Basically it means that boat real course over ground is different then direction the boat - so the GPS course is different heading - and it is possible that the difference can be like 30 deg.

OpenRTK330LI is a GPS/IMU integrated system, with Inertial measurements, it reflects the heading in 100 Hz real time.
