| System applies ray bending corrections in real time |
Y; can also be re-applied in post-processing |
| System is capable of collecting and integrating the SV-profile in real-time during data collection |
No; but the speed of sound at the sensors can be read continuously via a COM port, and applied in real-time and post-processing |
| Motion sensors compatible to the system |
Most industry-standard motion sensors are compatible with the SWATHplus range, including: POS/MV, Coda Octopus F180-series, TSS DM series, Ixsea Octans and Hydrins |
| Dynamic accuracy required from MRU (degrees) |
Ideally 0.025 degrees or better |
| Possible interfaces to the processing unit |
Ethernet |
| Online access to bathymetric data during collection |
Y |
| If yes, by which means? |
By TCP/IP port: data formats available from SEA |
| Additional remarks |
The sonar transducers are rated to 6000m pressure depth, for use on deep-towed platforms |
