On mine sites, pit lakes form as excavated mine pits fill with water; often the water is actually acidic, corrosive process leachate solution highly rich in dissolved components such as copper. The leachate may be removed and reprocessed to extract the desired metal. Usually, such pit lakes are too hazardous to survey on a manned boat so a USV is …

Grain from US farming is transported down the Mississippi River in enormous quantities for export to customers all around the world. The grain barges that have been transported downriver are unloaded at grain elevators and rapidly transferred to cargo vessels alongside the docks. Ships are continuously arriving to collect their grain cargo and safe operation of the terminal relies on …

Recognizing than using an unmanned survey boat for river bathymetry can generate substantial manpower and cost savings, Montana Department of Transportation studied available options closely. In order to prevent potentially unnecessary expenditure by choosing the wrong product, DOT staff tested the waters with a small inexpensive drone boat that was used in combination with their existing GNSS data collectors. While …

HydroQuebec in Montreal, Canada manage a large network of dams around the province and the hydrology group are tasked with conducting surveys around the dams to better understand the flow conditions through hydraulic models. As is common for surveying around dams, access for manned boats with people on the water in the immediate vicinity of the dam is severely restricted. …

Under the July summer sun in Arizona, USA, equipment gets tested at the extremes and in this case that was a CEE-USV hydrographic survey boat with CEESCOPE-LITE echo sounder. In the middle of the day, the shore acquisition computer supplied with the system – a silver Panasonic Toughbook – got so hot that the handle could not be used to …

In partnership with marine autonomy experts Dynautics Ltd and hydrographic survey acquisition software developer Eye4Software, CEE HydroSystems can now offer a uniquely simple robotic waypoint navigation controller for the CEE-USV™ remotely-operated hydrographic survey boat. In common with all other CEE survey equipment, the principal design criteria were simplicity and ease of use. Survey line planning and radio-link uploading of the …

For 2019 CEESCOPE models onwards, built-in differential GPS receivers will be exclusively Hemisphere’s Eclipse OEM receiver. Replacing the older Crescent and NovAtel OEMStar GPS boards, the Eclipse represents a huge increase in specifications for even the most basic CEESCOPE models. The latest Eclipse receiver, integrated at the electronic board level inside the CEESCOPE, offers an enormous increase in available channels, …

Barges and tow boats are used for transporting dry cargo along the Mississippi River system. From the lower Mississippi up the Ohio and Tennessee Rivers, goods such as grain, coal and soy beans travel to the gulf coast for export and steel and other products come into the US interior. Navigating barges along a flowing river is a difficult task! …

CEE HydroSystems recently worked with Survey and Planning firm Newton Denny Chapelle (NDC) to cover a stretch of river requiring a hydrographic survey near their office in northern New South Wales. Already offering a wide range of land-based survey services they were looking to expand their hydrographic capability and expertise and this survey task was seen as a great opportunity …

A series of six in-depth training videos have been completed for CEE customers. The new tutorials with nearly five hours of training show step-by-step instruction on the hydrographic survey process using Eye4Software Hydromagic software. From equipment setup, through data acquisition, troubleshooting, editing and final product generation the videos may be used to consolidate knowledge from a CEE training course or …
