The purpose of this publication is to provide the descriptions, procedures and detailed parameter explanations required to allow for safe and efficient use of the ST90 system. The publication also provides you with a thorough understanding of the parameters and adjustments provided by the ST90 system.
The vessel coordinate system is established to define the relative physical locations of system units and sensors.
Daily operation of the ST90 system may be disturbed by environmental situations that you are unable to control. Typical conditions are temperature and salinity layers, as well as deflections caused by increasing or decreasing water temperature.
The information from the transducer on the ST90 system is a continuous flow of analogue data. In signal processing, sampling is the reduction of this continuous signal to a discrete signal.
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.
