GeoSwath Plus Trials on Remus 100 AUV

Two surveys were carried out, four lines 500m long for system calibration in Megansett Harbour and eight lines 700m long for a survey trial in the bay, with the lines running across the shipping channel leading to Cape Cod Canal. Lines were run at 3m constant depth and the bathymetry data was processed in the GS+ software using an 80m swath width. The excellent quality of the navigation and depth mapping was demonstrated in the survey results, with clear definition of a 40cm high 10m period sand wave field in the shipping channel.

This survey trial was the end result of a successful integration project to combine the most widely used interferometric mapping sonar with the most successful small AUV, both systems manufactured by Kongsberg Maritime companies. Through linking these advanced technologies Kongsberg continues to bring the full subsea picture into sharper focus.
