SEISMIC MODULE OVERVIEW
This module acquires streamers and buoys data from the system called TRINAV and processes
them.
Then the positions of streamers and the different buoys are displayed on the electronic
charts. In addition the seismic module calculates and triggers alarms when targets enter the
security zone defined around the streamers or when the seismic vessel is sailing in dangerous
areas.
The Radar kit necessary to overlay the Radar video on top of the chart is installed on a remote
NetPC and should be configured as described below. A configuration drawing is given as
example of installation.
