The purpose of this publication is to provide the descriptions and procedures required to allow for efficient use of the ST90 system. The manual does not contain detailed information about functions, dialog boxes and operating parameters.
In selected views you can control how the vessel symbol shall "behave" in the presentation. The way the vessel moves in the presentation can be chosen either true or relative.
A current sensor can be connected to the ST90 system. This can for example be an acoustic Doppler current profiler (ADCP). The information from this sensor is presented in the applicable views.
Position information from external objects such as buoys, fish aggregating devices and other similar items can be imported into the ST90 system. The external objects are shown as hexagonal markers in the echo presentation.
In order to maintain a visual presentation of your vessel’s previous movements, you can draw these with a line. This line is drawn after the vessel symbol in the sonar views, and visualizes your past movements. We refer to this line as the History Line.
The functions and dialog boxes provided in the ST90 user interface are not described in this publication.
The technical specifications summarize the main functional and operational characteristics of the ST90 system. They also provide information related to power requirements, physical properties and environmental conditions.
The ST90 system can send and receive information to and from several different peripherals. All transmissions take place as datagrams with data sentences. Each datagram has a defined format and length.
