4.2.10 Enabling ‘Setup Mode’ to ignore GPS position problems
SMISealog is normally configured with the vessel at the wharf/Dock. As the vessel is not
moving SMISealog will flag the data as having a problem, therefore causing Piscatus3D
to ignore all data. There is a setup mode option at the bottom on the ‘System’ tab in the
SMISealog control panel. Place a tick in this option to make SMISealog ignore GPS position
problems so data can be checked in Piscatus3D. This option is not saved and will be
un-ticked when SMISealog is next loaded.
4.2.11 Receiving ARPA target data
The settings for receiving ARPA target data are on the ‘boat NMEA 2’ tab in the SMISealog.
SMISealog is only able to receive data from the radar NMEA string $RATTM. If this string is
being received that ARPA targets within that string will be listed on this tab. There are no
other settings which need to be adjusted.
4.3 Using tide adjustment
4.3.1 How tide adjustments are calculated
Piscatus3D is a utility built into SMISealog that uses data from tide stations around the world
to calculate the tide. Corrections can then be applied to depth data stored in the Piscatus3D
database. The tide station used to calculate the current tide is the closest station within
range of the boat’s position. This range is 40,000m (40km) by default, but it can be changed.
Once the tide station is found, the GPS date/time (or, if unavailable, your computer’s date/
time) is used to calculate the tide.
4.3.2 Viewing current tide adjustment
To view the current tide at the boat’s position, open the ‘SMISealog Control Panel’ window,
click the ‘Tide Adjustment’ tab and then the ‘Current Tide’ tab. This tab displays the data used
to generate the tide value, and when it was last updated.
