b Measure the vertical distance from the waterline and down to the transducer face.
This is the Z value. The value is positive because the sensor is located under
the origin.
c Measure the horizontal distance in parallel with the X axis from the origin to
the vertical line.
This is the X value. The value is positive because the sensor is located in front
of the origin.
d Measure the horizontal distance in parallel with the Y axis from the origin to
the centre line.
The sensor is on the centre line, but the origin is located on the starboard side.
This is the Y value. The value is
negative because the sensor is located on the
port side of the origin.
e Type the values you have found for X, Y and Z into the
Transducer
page when
you install the transducer in the MF90 user interface.
3 Measure the physical location of the global positioning system (GPS) antenna.
There are two GPS antennas.
Both are placed on the main
mast, one on each side, each
two meters from the mast.
The mast is located on the top
of the bridge, aft of origin. We
will measure the coordinates
to the port antenna.
Note
In this context, the GPS
antenna is regarded as the
sensor.
a Draw a vertical line from the sensor and down.
b Measure the vertical distance from the waterline and up to the sensor.
This is the Z value. The value is negative because the sensor is located over the
origin.
c Measure the horizontal distance in parallel with the X axis from the origin to
the vertical line.
This is the X value. The value is negative because the sensor is located behind
the origin.
