Attention:
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.

| sound velocity | sound velocity | m/s |
| water temperature | water temperature | °C |
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 MiniSVS 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.
