The NORBIT WINGHEAD is a very compact ultra-high resolution multibeam survey system with the following key features.
All components fit in a single pelican case that meets airline baggage requirements:
– NORBIT WINGHEAD® i77h sonar with integrated IMU
– GNSS antennas
– Topside unit
– Sonar and antenna cables
– Optional sound velocity profiler
– Optional LiDAR

NORBIT’s curved array technology allows beams to be steered electronically without physically rotating the sonar.
– With conventional multibeam systems, beam width resolution degrades significantly as the beam
steering angle increases away from nadir.
– With curved arrays, beam spreading is significantly less, which makes the NORBIT WINGHEAD ideal
for quay wall inspection work where high resolution is required.

The multibeam can be combined with the optional NORBIT iLiDAR to obtain a full picture of the infrastructure above and below the waterline. This provides context for the multibeam data and aids interpretation of the results.

The NORBIT WINGHEAD generates up to 1024 true beams per ping, providing ultra high sounding density on the quay wall, which is essential for reliable inspection work.

Rocks which have fallen from the quay side into the water are detected in both the Lidar and multibeam data.
The WINGHEAD offers 0.5x0.9°beams at 400kHz, providing extremely high resolution data which enables tires and small objects, such as tree branches and ropes, to be detected.
