Configuration Of Navigation Sensors; How To Verify Source Of Navigation Sensors - Furuno FEA-2807 Operator's Manual

Configuration of Navigation Sensors

The operator can select navigation sensors for use in navigation and view their current values. There are "pages" for
speed and course and position. The figure below shows the SPD/CRS page.
The presence or absence of a checkmark
in a checkbox shows whether the sensor
is used for integrated navigation or not. If
there is no value shown for a sensor, this
means that the sensor is not valid. Note
that the content of these pages depends on
the sensors that are in use on the ship.
To display the Sensors dialog box, put the
cursor on the position indication in the
information area then right-click.

How to verify source of navigation sensors

In a multiple workstation environment, verify that the sensor sources indicated are the intended ones. This can be
done on the Sensors dialog box.
SPEED settings (SPD/CRS page)
Select both Log and Dual log, if they are available, or select the one that is available, on the SPD/CRS
(Speed/Course) page.
Note that manual speed should only be used in an emergency, when no other speed reference is available.
Remember that position sensors are also available as speed sources. If neither Log nor Dual log is available, you can
use a radar as the source for speed and course.
GYRO settings (SPD/CRS page)
Select Gyro1 or Gyro2 on the SPD/CRS page. In the typical installation Gyro1 is connected to a traditional
gyrocompass, while Gyro2 receives gyro value from either an autopilot or a DGPS sensor.
Manual heading should only be used in an emergency, when no other heading source is available.
A rate gyro is always automatically selected.
