Integrated bathymetry with SBG Ekinox
iWBMS Ekinox combines SBG Ekinox GNSS/INS with broadband multibeam sonar. Its compact arrangement supports mobilisation for shallow-water, harbour, river and coastal surveys. An integrated NTRIP client and Ethernet interface support correction-data and survey-data integration. Ekinox navigation specifications differ from Applanix-based iWBMS models; comparisons should use the same antenna spacing and positioning solution.
Survey workflow and quality control
Before mobilisation, the coordinate system, vertical reference, antenna offsets and sonar mounting geometry are defined. Sound-speed profiles, time synchronisation and angular alignment are checked during trial lines. Sonar observations are assessed alongside position and motion data, with overlapping lines and cross lines used to check consistency.
Deliverables can include a bathymetric surface, sections, a seabed model for volume calculations or structure inspection data, depending on the application. Acoustic resolution alone does not represent final georeferenced survey accuracy. Water depth, seabed material, vessel motion and selected software options are considered together when specifying the system.
