| System Accuracy in relation to IHO S44-4, meets S44 order |
Special |
| Max. allowable survey speed to allow for this accuracy (knots) |
Depth dependent |
| System applies ray bending corrections in real time |
Yes |
| System is capable of collecting and integrating the SV-profile in real time during data collection |
Yes |
| If yes, explain the process |
• SSV and SVP are time stamped, merged and taken into account for ray bending processing
• SSV is taken into account for beamforming processing
• The time stamped profile is stored as ACII-file |
