Settings / Ownship Settings / Heading Offset
These settings control an offset to Own-Ship heading. The offset is an adjustment added to the heading sensor data for Own-Ship. This can be useful in situations where the heading value being received is innaccurate. Also, it is needed for use with some PPU devices (typically multi-pod devices) where the orientation of the two pods affects the received heading.
- Heading Offset: (Only SEAiq Pilot) The heading offset is added to the sensor value to generate the heading to use. The default heading offset is 0° (no change). Negative values correct to Port and positive values correct to Starboard. Normally the desired setting is either 90° or -90°. The heading offset is associated with vessels (according to their MMSI). Once changed, the Heading Offset maintains its value. It is necessary to change the setting back to 0° when you no longer need it.
- Calculated Heading: This shows the current (possibly corrected) value of the heading.
- Add 1 Degree: Adjust by 1° to starboard.
- Subtract 1 Degree: Adjust by 1° to port.
- Add 10 Degrees: Adjust by 10° to starboard.
- Subtract 10 Degrees: Adjust by 10° to port.
- Slave is Forward: Set heading correction to 0° (no correction). This corresponds to the slave being ahead.
- Slave is to Port: Set heading correction to 90°. This corresponds to the slave being to port.
- Slave is to Starboard: Set heading correction to -90°. This corresponds to the slave being to starboard.
- Slave is Astern: Set heading correction to 180°. This corresponds to the slave being directly astern.
- Automatic Heading Offset: (Only SEAiq Pilot) When enabled, the user Heading Offset will be automatically be prompted select a new heading offset when it differs from AIS heading by more than 30°. When the offset setting is within 10° of cardinal direction (0° / 90° / -90° / 180°) then the cardinal direction is used instead.
