Since 2011, CEE HydroSystems has been supplying compact echo sounders for USV deployment and manufacturers of remote survey boats have used CEE single beam sonars as standard factory options. Our experience has led us to better understand the requirements for successful hydrographic surveying with a USV, and we have developed a unique ability to offer single beam solutions tailored for USV surveys.
We learned that mobilizing and setting up a USV with its various instruments and telemetry components might represent a significant portion of the total survey duration, and the overwhelming majority of the frustration. By putting all of the constituent parts (bathymetry, GNSS position, data multiplexing, and telemetry) into a single component: the CEESCOPE-USV™, many of the integration problems disappear. Simply turn on the CEESCOPE-USV™ echo sounder and survey data start being recorded; as soon as the CEE LINK™ shore radio module is powered-up and within range, data streams to the shore. Simply connect a data acquisition PC to start collecting data. The CEESCOPE-USV™ critical success factors for USV design and operation include:
Easy to operate.
The USV should be a survey tool and not a science project.
Easy to integrate external GNSS.
The CEESCOPE-USV™ will take in external position data with practically no changes in setup needed.
High quality shallow water bathymetry data – critical for USV operation.
The 200 kHz CEESCOPE-USV™ is able to maintain accurate bottom tracking in <15 cm (6″) water depth.
The CEESCOPE-USV™ uses 1PPS GNSS time tags on all data collected, eliminating detrimental effects from radio transmission.
The CEESCOPE-USV™ design allows a greater safety factor for critical components, such as radio modules.
