Compact CEE LINE Echosounder Kit

Packaged into a complete mounting kit for basic hydrographic surveys, the CEE Hydrosystems CEE LINE is aimed at land surveyors wishing to undertake small projects. With the CEE LINE, a rudimentary echosounder for a basic survey is not needed. The CEE LINE has a simple communication interface and does not ever need charging courtesy of its USB connection. The ‘sonar on a stick’ concept has been around for a few years, and some of the equipment used has been around even longer. The CEE LINE offers a new approach to this survey setup. With no battery or Bluetooth required, the... (read more)

LinkQuest Enters Multibeam Echosounder Market

LinkQuest, USA, recently added a multibeam echosounder product into its family of acoustic instruments. The EchoSweep 300 multibeam echosounder is a high-resolution, highly robust and cost-effective swath bathymetric system for mapping the sea floor, inland waterways and reservoirs. The EchoSweep 300 system is capable of reaching up to 280 metres in range with 140 beams. It operates at 260kHz and has a swath coverage of 140 degrees. The EchoSweep 300 multibeam echosounder maps the sea floor by a sweep of very narrow acoustic beams. It can map the sea floor faster and in more detail than a single-beam echosounder, thereby significantly... (read more)

Multibeam Echosounder for Medium to Deep Water

The RESON SeaBat 7160 multibeam echosounder has been developed for marine exploration, seafloor habitat mapping and hydrographic charting in medium to deep water (3 to 3,000m). Equipped with X-Range, it provides improved system immunity to external noise. The system can operate in water depths of between 3 to 3,000 metres, offering up to 512 high-density equidistant beams with a selection of coverage modes including features such as variable and steerable swath, together with real-time pitch and roll stabilisation maximising useable swath and performance. The SeaBat 7160 also provides the collection of high-density water-column data all wrapped up in a processing... (read more)

Forth Ports to Use NORBIT Multibeam Echosounder

NORBIT has supplied Forth Ports, one of the UK’s largest port groups, with multibeam survey capability for the River Forth and the River Tay. The NORBIT iWBMSh is in place with QPS QINSy and Qimera software, along with associated sensors and training with an investment by the port business exceeding GBP250,000. NORBIT has also supplied the integrated iLiDAR system to Forth Ports, facilitating an integrated survey system allowing both bathymetric and terrestrial spatial data to be simultaneously collected by a single source system. Alan McPherson, Chief Harbour Master commented that as the statutory River Authority for the River Forth and... (read more)

Bluetooth Android App for SonarMite Echosounder

The SonarMite app is an Android app designed to work with the SonarMite Bluetooth echosounder used in hydrographic surveying applications. The app is dedicated to connect to the SonarMite and facilitate most simple commands via pre-programmed buttons. Dedicated buttons give a more intuitive interface than using the dropdown keyboard or voice interface. With the demise of Hyperterminal as a standard terminal application the end user is left with little choice for a simple communications programme with serial data devices. Connecting via Bluetooth is cleaner than USB cable, as there are no wires and the connection is independent of baud rate... (read more)

Artefacts in Multi-beam Echosounder Data

This article is about my thesis project, which I did in collaboration with Auke van der Werf at the Dutch Nautical Academy at Terschelling (the Netherlands). The research for the thesis was done at the Dutch Directorate General for Public Works and Water Management (Rijkswaterstaat). This article presents a subset of the thesis. I would like to share the knowledge I gained and the lessons I learnt about lever-arm errors, motion time delays and yaw misalignment, which can result in dynamic motion residuals, also called artefacts or wobbles.<P>   Over the last decade, Rijkswaterstaat (part of the Dutch Ministry of...

CEESCOPE-USV Echosounder for Remote Hydrographic Surveying

CEE HydroSystems has announced the release of a singlebeam echosounder survey system, designed specifically for the growing number of shallow-water unmanned surface vehicle (USV) survey applications using both commercially-available and custom-manufactured remotely operated boats. The CEESCOPE-USV is an echosounder, GNSS and broadband radio telemetry package that can be installed on practically any remotely operated boat. As an entirely self-contained module requiring no interface with the USV, challenges of instrument data integration on the vehicle are minimised or eliminated. Rigorous data handling eliminates latency concerns resulting from radio transmission to the shore, and the CEESCOPE-USV brings a clear separation between the... (read more)
