4. ADJUSTMENT
4-18
3. On a separate piece of paper, plot the current speed and direction based on the table 3.
Confirm that the current reading is stable in any ship’s heading. (Only when the current
changes minimally while the ship runs square course.)
Current
Ship’s route
Milepost test-2
Confirm that the currents orient the same direction. If not, the interference from other
equipment, air bubbles and noise may be present. Also, take into account that interference
from air bubbles may occur since there is no load in the milepost test.
Note 1:
When a “bearing sensor” is connected in lieu of a gyrocompass, accurate
measurement of current direction is not expected because the bearing data itself is
in error.
Note 2:
Note that it is difficult to distinguish this unit reading when the above test is done
where the current is complex.
