Input Distribution
4.5.1 Sound Velocity
To achieve correct beam steering in equidistant mode, the sonar needs to
have an up-to-date online sound velocity measurement from the water in
the area of the sonar head. The sound velocity
must always
be selected
in the IO Module, even if PDS2000 or a different acquisition system is
used. Set the associated settings for the connected sound velocity device.
4.5.2 Clock
To achieve correct time stamping of transmitted pulses it is necessary to
send time to the sonar processor. The SeaBat uses the GPS PPS system
to achieve this. From the GPS receiver, the SeaBat needs the TTL 1PPS
pulse and the qualifying time message (normally ZDA). The clock
synchronization must always be entered in the IO Module.
If the 1PPS is not detected during the sonar operation, the led indicator
in the toolbar changes from green to yellow/orange to red and in the
Service page in the Status tab the error is displayed. Set the associated
settings for the connected external clock device.
4.5.3 Attitude
Select the associated settings for the attitude sensor when connected to
the SeaBat Processor.
Use the Hardware Pane (see Hardware on page 40) to setup the attitude
sensor used for the motion stabilization of the sonar.
4.5.4 Position
Select the associated settings for the GPS position sensor when
connected to the SeaBat processor
4.5.5 Heading
Select the associated settings for the heading sensor when connected to
the SeaBat processor
4.5.6 Pan and Tilt
Select the associated settings for the Pan and tilt sensor when connected
to the SeaBat Processor.
Pan and tilt is used when the mounting angles of the sonar can be
changed mechanically These angles can be interfaced to the SeaBat.
