These settings configure SEAiq Pilot for use with Navicom Dynamics Portable Piloting Units. See below for more information on using SEAiq with Navicom Dynamics products.
Navicom Dynamics PPUs support at most 5 WiFi client at a time.
Each time a ChannelPilot is turned on, it requires you select the vessel the device is attached to. This is used to help calibrate the gyroscope and determine information such as the vessel name and size.
If you are using a ChannelPilot a vessel without AIS (such as a barge), you can trigger the gyroscope to calibrate itself in Free-Running Mode by selecting the last entry in the table, Vessel Does Not Have AIS. In Free-Running Mode, you will need to adjust Settings / Own-Ship / Heading Offset and then periodically update it if the gyroscope slowly wanders.
Similarly, you can also make this selection by graphicly selecting a target on the Navigate tab or by finding the vessel you want on the AIS tab:
Vessel Auto-Select is used to automatically prompt you when aboard a vessel. A vessel is selected by comparing your position and course with AIS targets in your area (see documentation for Vessel Auto-Select for more information about the criteria used to choose the most likely AIS target).
If vessel is not selected for some reason, use one of the other methods to manually select your vessel. If you are on a vessel such as a barge, you will need to use Method 1.
For HarbourPilot selecting a vessel is not as important as ChannelPilot but can still be helpful in order to acquire the vessel name, size, and other information from AIS. Vessel Select is also used in order to suppress the AIS target corresponding to Own-Ship (see Suppress Selected Vessel).
Follow the same instructions for ChannelPilot to select vessel. The difference is that the HarbourPilot will not generate the final confirmation dialog and that the HarbourPilot does not have (or need) a Free-Running mode.
Depending on how a HarbourPilot is oriented, you may need to adjust the heading received from the device. This is done by adjusting Settings / Own-Ship / Heading Offset, which is added to the value received from the PPU. You should first set the basic orientation and then fine-tune as needed.
This may also be useful for the ChannelPilot when the heading value received from AIS and used to synchronize the gyroscope is inaccurate, or when operating free-running mode.
Vessel Auto-Select (Only SEAiq Pilot) : When enabled, the user is prompted to select a vessel when nearby. The user is prompted when the following conditions are met: the target is not a pilot boat, port tender, tug boat, or recreational vessel, you are most 0.25NM from vessel, your device's course is within 2kn of vessel's course (measured by comparing course vectors). You can be asked to select a target at most once every 5 minutes.
If you already have a target selected, you must be at least 2NM away from the current target before another target is suggested.
Always Derive COG/SOG (Only SEAiq Pilot) : When enabled, COG/SOG will always be derived based on recent GPS positions. Any COG/SOG data from NMEA (Primary or Extra) is ignored.
It is almost always preferred to have your GPS hardware determine COG/SOG since that hardware has access to the most complete information about position. If uncertain, do not enable this option.
Derive COG/SOG When Needed (Only SEAiq Pilot) : If your device sometimes does not provide course and speed sensor data (COG/SOG), you can enable this setting so this data will be derived based on recent GPS positions. When enabled and COG/SOG data from NMEA is not available, the derived value is used.
This is normally only used with the Navicom Dynamics Channel Pilot product.
It is almost always preferred to have your GPS hardware determine COG/SOG since that hardware has access to the most complete information about position. If uncertain, do not enable this option.
Derive COG/SOG When Slow (Only SEAiq Pilot) : When enabled, COG/SOG will be derived from GPS position when speed is less than a given threshold.
It is almost always preferred to have your GPS hardware determine COG/SOG since that hardware has access to the most complete information about position. If uncertain, do not enable this option.
The current Navicom Dynamics products use per-model configurations, as listed below. Presets for configuring these devices are provided in Settings / NMEA & AIS / Standard Devices.
Prior models use a configuration that is dependent on the serial number of the device, as described below. If you have any questions, refer to your product documentation.
The Host should use an IP address that is determined by the product serial number. The IP addresses take the form 192.168.X.Y, where X is the first digit of the serial number and Y is the last 3 digits of the serial number (discarding any leading zeroes). For example:
The first digit of the serial number also corresponds to the version of the device (eg, Mk3 serial numbers start with 3). This is explained in the documentation that came with your device.
