Components
The SES system consists of the transducer, the main unit and a data aquisition PC. The software "SES for Windows" is installed on the aquisition PC. Furthermore two PCs with the processing software "ISE Post Processing Software for SES2000" are available on the bridge deck and in the Messraum.

Central geographical ship's position and time standard
| Metadata (Metadata Plugin) |
|---|
| The GPS position of the Trimble GPS receiver antenna is stored in the data files. The position is NOT centralized to the SES2000 transducers. Heave correction between the motion sensor and the transducer are calculated in the motion sensor and corrected values are transferred to the SES. Time synchronisation is achieved via NTP. |
|
Rawdata storage on board
| Metadata (Metadata Plugin) |
|---|
| The data acquisition software creates raw data on the local drive of the computer. The SES data are not transferred to DShip. |
