The figure above shows the source of water speed used for drift calculation.
Smg/Cmg used by the system
Speed (water speed) used by the system
Heading used by the system
Drift used by the System is shown SENSOR Other Sheet. In this case it is from manual drift). Following
alternatives are available: (log) if value is based on log or dual axis log; (posit) if value is based on position sensor;
(filter) if value based on Kalman Filter; (man) if value is based on manual entry.
No speed or course available
It is possible that user has not selected any speed or course sensors, or that the selected sensors doesn't have any
valid values. This kind of a situation is critical for the system, because it cannot perform even dead reckoning.
When no speed source is available the system generates alarm "2001 No speed available". When no course source
is available the system generates alarm " 2002 No course available".
