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.

Data logging, storage and archiving
Logged parameters
| Parameter | Sensor Output Type | Unit |
|---|---|---|
| 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.
DShip
Uncorrected measurement data.
Multibeam
Multibeam echo sounder Simrad EM710 is receiving sound velocity data from this sensor to be used as c-keel value. If raw data logging of multibeam echo sounder is switched on, c-keel value is stored in Simrad Processing File of type *.all
