Own-Ship Settings

AIS Antenna Position

• Source : Select AIS or manual offset position.
• Distance to Bow : Manual setting for GPS antenna position. Indicates how far behind the bow the antenna is.
• Distance from Centerline : Manual setting for GPS antenna position. Indicates how far to Port or Starboard the antenna is relative to the centerline.

Ext GPS Antenna Position

• Distance to Bow : Manual setting for External GPS antenna position. Indicates how far behind the bow the antenna is. This is used for PPU's with integrated GPS.
• Distance from Centerline : Manual setting for External GPS antenna position. Indicates how far to Port or Starboard the antenna is relative to the centerline. This is used for PPU's with integrated GPS.
• Use as Conning Position (Only SEAiq Pilot) : When enabled, the external GPS Antenna distance to bow is used as the position on Own-Ship for predicted course vectors, beam lines, EBL/VRM/CL, XTD, etc. Note that (for these purposes) the conning position is always placed on the centerline of the vessel.

Draft

• Source (Only SEAiq Pilot) : Select AIS or manual draft setting.
• Draft (Only SEAiq Pilot) : Manual setting for draft of the vessel. This can be used to help configure Safety Depth and Safety Contour.

Air Draft

• Air Draft (Only SEAiq Pilot) : Manual setting for air draft of the vessel. This value is used unmodified to determine the Safety Air Draft, which is used to calculate clearance and other air-gap related presentation.

Heading Adjustment

• Heading Offset (Only SEAiq Pilot) : Depending on how the product is oriented on the vessel, it may be necessary to set a heading correction.

  Follow these instructions to adjust it:

  • Press the Heading Offset setting.
  • Select one of the common orientations or enter a value.
  • Confirm resulting heading is correct.
  • Adjust with +/- buttons if necessary.
  • Return to the Navigate tab to further verify correctness of the setting.

Block Coefficient

• Block Coefficient (Only SEAiq Pilot) : This value is used to estimate Squat. It must be in the range 0 to 1. You must manually enter a value for the current vessel. See Settings / Status / Squat for more information.

Windage

• Lateral Windage (Only SEAiq Pilot) : Manual setting for windage of the Own-Ship. This can be used to help estimate wind forces on the vessel.

Manage

• List All (Only SEAiq Pilot) : List all vessel records.
• Import (Only SEAiq Pilot) : Import vessels.
• Export All (Only SEAiq Pilot) : Export all vessels.
• Erase All (Only SEAiq Pilot) : Erase all vessel records, after confirmation. This cannot be undone.

Advanced

• Default to Using Ext GPS as Conning Position (Only SEAiq Pilot) : When enabled, new vessesls will default to using External GPS Offset as conning position. This is a setting that is retained across all vessels.
• Reset Ext GPS Antenna Position When Own-Ship Changes (Only SEAiq Pilot) : When enabled, External GPS Antenna Position will be reset when changing to a new vessel. This is typically used with Use AIS Distance to Bow as Default for Ext GPS Offset and Use PPU Baseline as Default for Ext GPS Offset to trigger an automatic value being filled into the External GPS Antenna Position (otherwise the previously filled value will be used). This setting is retained across all vessels.

• Use AIS Distance to Bow as Default for Ext GPS Position (Only SEAiq Pilot) : When enabled, new vessesls use AIS Distance to Bow as the default value for External GPS Distance to Bow. This is typically used if your External GPS antenna will normally be placed a similar distance to the bow as the AIS antenna.

  For this to be activated the following conditions must hold:

  • The Distance to Bow for External GPS must be unset (equal to 0m) for this vessel.
  • Position source must be from an External GPS (not AIS or Virtual Boarding).
  • Distance to Bow reported by AIS for the vessel must be at least 1m.

  This setting is retained across all vessels.

• Use PPU Baseline as Default for Ext GPS Position (Only SEAiq Pilot) : When enabled, new vessesls will default to using 1/2 baseline as the default value for External GPS Distance to Bow. This is typically used with 2-pod PPUs that are expected to be placed in a symmetrical placement.

  For this to be activated the following conditions must hold:

  • The Distance from Centreline for External GPS must be unset (equal to 0m).
  • Position source must be from an External GPS (not AIS or Virtual Boarding).
  • PPU must report a Baseline value of at least 1m.
  • Heading Offset must be within 10° of positive or negative 90°. This is used to determine if offset is to port or starboard.

  This setting is retained across all vessels.

• Unmangle AIS Information (Only SEAiq Pilot) : This option is used on the occasional vessel where the AIS antenna position reports a position different than where the SOG and COG is being calculated for. This causes incorrect prediction vectors to be displayed, most noticeably when vessel is rotating.

  When this option is enabled, the antenna position is "moved" to the Ext GPS Antenna position. This change only affects the prediction vectors and associated data; the position of the vessel is unchanged.

  If unsure about how to use this setting, you should leave it disabled.

• Barge (Only SEAiq Pilot) : Settings to display a barge attached to Own-Ship.
• Turbine (Only SEAiq Pilot) : Settings to display an oversize wind turbine as cargo on Own-Ship... if you happen to be carrying such an item.

Conning Position

Various information are based on the position of the Conning Position. These include the following:

• Displayed COG and SOG values.
• Graphical course vector.
• Cross-Track-Distance (XTD). Note that Show XTD for Bow & Stern will cause XTD to be shown from bow and stern.
• Display of estimated mark position on wharf for Conning.

The actual position used for this point of reference may vary depending on various factors listed below.

• If size of ship, antenna offset, HDG, or ROT are unknown, then the Conning Position is the position of the GPS antenna. If only ROT is missing from the above items, then the Conning Position will be amidships at the position of the GPS antenna offset.
• If the above items are known and Use GPS Antenna for Default Conning is off then the center of the vessel will be used as Conning Position.
• Alternatively, if Use GPS Antenna for Default Conning is on, then the amidships position of the GPS antenna is used as the Conning Position.

Note that when course information (graphical vector or COG/SOG) is shown for a different location than the GPS antenna position, then the values are adjusted according to the different rotational motion of the two positions. For these calculations, the center of the vessel is used as the point around which the vessel is rotating.
