Exceptional imagery for Bluefin Robotics with Sonardyne Solstice

World 鶹ýӳ,


Following the successful integration of Sonardyne International Ltd.鶹ýӳs Solstice Side Scan Sonar with a Bluefin Robotics Bluefin-12 Autonomous Underwater Vehicle (AUV), the results of recent payload testing have produced higher quality imagery than that currently available from conventional sonar.

The most recent trials of the Bluefin-12 AUV with integrated Solstice were conducted from Bluefin Robotics鶹ýӳ headquarters in Quincy, Massachusetts, where the AUV was deployed from Bluefin鶹ýӳs vessel, the R/V Resolution, to perform short missions around the Boston Harbour area in approximately 15 m of water.

Each mission consisted of legs of 500 m, during which the AUV flew in a pattern commonly known as 鶹ýӳmowing the lawn.鶹ýӳ This is where the vehicle makes a pass over one area and then comes right back alongside it, running in parallel lines that will overlap and cover the entire bottom to form an image of the sea floor.

鶹ýӳWe are pleased with how quickly we were able to integrate the sonar and collect high-quality data,鶹ýӳ said Will O鶹ýӳHalloran, Marine Operations Manager at Bluefin Robotics.

鶹ýӳThe imagery is some of the best I have seen in my 10 years of operating AUVs and reviewing data sets. The Solstice sonar is an excellent payload option for our clients who want exceptional imagery from low-logistics, rapidly-deployable AUVs.鶹ýӳ

鶹ýӳA pipeline end manifold (PLEM) surveyed during the trial provided an excellent target to show the resolution and contrast performance of Solstice. This PLEM consists of a large square template, pipe and mattress protectors; you can see where the individual elements of the mattress are clearly resolved in the imagery,鶹ýӳ commented Nick Swift, Sonardyne鶹ýӳs Business Manager for Maritime Security.

鶹ýӳThis imagery is further proof of Solstice鶹ýӳs exceptional image quality and is thanks to advanced processing techniques, inbuilt technologies and a unique array design for minimising multipath effects.鶹ýӳ
