The Valeport Mini SVP is permanently integrated and operates autonomously.

Summary

The Valeport miniSVS Sound Velocity Sensor provides high resolution, high accuracy sound velocity data. The basic principle is “time of flight”; that is to say, the sound velocity is calculated from the time taken for a single pulse of sound to travel a known distance.

Central geographical ship's position and time standard

Time synchronization and geographical positioning is done by DShip receiving the data for logging.

Rawdata storage on board

Sound velocity raw data (uncorrected measurement data) are stored in data acquisition system DShip.

Multibeam

Valeport MiniSVP can be selected in Multibeam Echo Sounder control software SIS to be source of c-keel value. If so and raw data logging of multibeam echo sounder is switched on, c-keel value is stored in Simrad Processing File of type *.all

DShip

 Uncorrected measurement data.

Data archiving on land

After the cruise the DShip data set can be extracted from https://dms.awi.de.
