WINGHEAD i80S
Motion-stabilised detailed mapping
WINGHEAD i80S combines a curved sonar array with OceanMaster GNSS/INS. The narrow across-track beam supports investigation of vertical and complex surfaces such as quay walls and bridge foundations. Roll, pitch and yaw stabilisation help maintain the scan pattern during platform motion. The specifications below apply to the linked original i80S brochure and should not be confused with i80S Long Range or Apogee versions.
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.
