INTEGRATED INERTIAL NAVIGATION SYSTEM
The HAIN Subsea 7000 with co-located DVL is a fully integrated inertial navigation system for subsea vehicles. The system can be aided from acoustic positioning systems, doppler velocity and pressure sensors.
The integrated solution designed for operation on an AUV, ROV, towed fish and any other subsea vehicle down to 7000 meters water depth, consists of an inertial measurement unit, doppler velocity log and onboard navigation processing. The HAIN unit receives the subsea vehicle position aid from an SSBL system on a surface vessel or a sparse LBL system on the subsea vehicle. In addition, to further improve position accuracy, the co-located DVL and pressure sensor can be used as aids to the inertial solution.
The cNODE ® Micro transponder is rated to 600 metres and is small and light enough to be used by divers and shallow water ROV’s. Operating on Kongsberg Cymbal digital acoustic protocols, the cNODE ® Micro provides the optimal positioning performance with the Kongsberg range of SSBL systems, from μPAP ® through to HiPAP ®.
The cNODE ® Micro is extremely flexible featuring Cymbal digital telemetry and both SSBL & Long Baseline positioning capabilities. With range accuracies of better than 2 cm achievable, measured baselines between transponders on the seabed provide capabilities for simple diver metrology or archeology.
The telemetry capability allows the battery status to be read during operation and the integrated tilt sensor can be turned on and off with positioning updates. Multiple cNODE ® Micro transponders can be interrogated simultaneously in SSBL positioning mode using the μPAP ® and HiPAP ® Fast track feature to ensure the fastest possible updates during operation.
High Resolution, Multi-frequency Fan/Cone Beam Transducer with Tilt Block and Internal Compass
This 1171-series sonar head uses new transducer construction techniques optimized to provide low noise, high-resolution sonar operation at frequencies from 600 kHz to 1.5 MHz. This wide-frequency, dual transducer configuration is ideal for both imaging and profiling applications where data clarity supersedes any other requirement at operating ranges from 25 m out to more than 150 m. This 1171 sonar head is well suited for bottom clearance, body recovery, underwater construction support, pipeline and cable surveys, bridge and pier inspection applications. The open face transducer design is ideal for all water temperatures, and the beam pattern is not affected by thermal defocusing. The adjustable tilt block allows the operator to mechanically set the transducer tilt up to +/- 30°, as required for optimal imaging data acquisition. In addition to heading information, the internal compass module also provides pitch and roll information. This sonar head is operated using the MS 1000 software.
