How Unmanned Survey Vessels Benefit Bathymetric Survey Operations
Marine USVs such as the Apache Unmanned Survey Vessels (USV) benefit different bathymetric survey operations by eliminating the need for human supervision and enhancing productivity and overall safety. Bathymetry includes obtaining recurrent measurements of the water depth, for example, to determine whether a vessel can make it to a berthing area or whether dredging is required to create adequate depth. Additionally, in dam and reservoir areas, the depth level is required to calculate the capacity of the dam year after year as siltation causes the bed level to rise, which reduces their overall capacity. In general, limited information is known about the seabed, lake, or river floors due to low-resolution or obsolete maps due to a lack of time series data. In the case of dams, the bottom is mapped only during construction: time series data are not recorded as depths will be difficult to measure over time using traditional surveying vessels. Figure 1. The Apache 3 USV, a cost-effective single beam marine drone with the dual GNSS positioning and heading sensor and IMU sensor for the bathymetric surveys of lakes, inland rivers, and coastal areas from CHCNAV. Offering a more affordable alternative to traditional manned marine vessels, marine USVs allow bathymetric survey operations to be carried out in an automated way, with the objective to increase the range and complexity of the automated underwater tasks while at the same time reducing the need for human supervision. Additionally, their portability allows for use in remote and hard-to-reach locations. PROVIDING POSITIONAL ACCURACY TO LARGE DEPTH MEASUREMENTS The Apache Series (the Apache 3, 4, and 6 USVs) integrates unmanned navigation and topographic surveying technology, providing a stand-alone hydrographic solution. Its main component consists of an autonomous, self-contained hull vessel that sails autonomously to complete the given task, from bathymetric surveying and mapping to channel surveys or geological exploration. Also, it is equipped with a single beam (multibeam) sounder to find the depth and calculate the level of the seabed. Depth is determined using sonar to transmit sound pulses into the water and calculate the time interval between transmission and return of a pulse. Figure 2. Bathymetric survey with the Apache 6 USV, a full-integrated innovative solution for 3D bathymetric survey, underwater object positioning, offshore construction, underwater archaeology, and wrecked rescue from CHCNAV. Integrating a GNSS Real Time Kinematics (RTK) system using a network of fixed ground reference stations to broadcast the difference between positions given by GNSS satellite systems and known fixed positions, improved positional accuracy is provided from the nominal GNSS accuracy of several meters to about 2-3 cm. The rover’s GNSS+INS is built-in in into the marine drone, and a base station is installed on the ground. The depth measurements are recorded using CHCNAV hydrographic survey software and transferred to the ground station through an RF communication system. USER APPLICATIONS The Apache series (the Apache 3, 4, and 6 USVs) from CHCNAV is designed for the efficient hydrographic, bathymetric, and hydrological surveys of lakes, inland rivers, and coastal areas with the goal of underwater object positioning, offshore construction, underwater archaeology, and wrecked rescue. Figures 3. The 3D modeling of the bridge columns in the underwater area; the project was realized with the Apache 6 USV from CHCNAV. The software provides 3D models of the ground, contour, and depth based on the data collected by the vessel for various user applications: the processed data can, for example, serve as a 3D baseline reference to verify the amount of silt removed. After re-mapping the same area after desilting completion, both layers can be compared to estimate the amount of silt removed. This way, the mapping of a lake’s bed mappings can be used for change detection over time. Figure 4. The 3D modeling and capacity calculation of the large water reservoir; the project was realized with the Apache 3 USV and AlphaAir450 Lidar from CHCNAV. Robust and versatile, the USVs from CHCNAV can be fitted with instruments such as single or multibeam echo-sounder, GNSS RTK receiver, and other sensors to reduce survey time, improve work efficiency, and output high-resolution data that always match the most demanding hydrographic survey project requirements. ___ About CHCNAV CHC Navigation (CHCNAV) creates innovative GNSS navigation and positioning solutions to make customers' work more efficient.

How to create the digital model of the water reservoir in just 1 day
Managing large water reservoirs can be challenging over time due to inaccurate or outdated geographic information, resulting in discrepancies between actual and initial design data. To effectively maintain reservoirs, it is essential to use advanced measurement methods, such as surveying and mapping with LiDAR scanners and unmanned vehicles that help timely provide accurate monitoring and calculation of water storage volume as well as forecasting and simulation of hydrological conditions. ABOUT THE PROJECT In this one-day project, it was demonstrated that the use of a hydrographic USV to obtain underwater mapping and a UAV equipped with a LiDAR scanner to obtain reservoir boundaries and topographic data results in the simplified and efficient management of large water reservoirs. The APACHE 3 USV with single beam echosounder and the AA450 LiDAR scanner installed on the unmanned aerial vehicle were used to perform measurements above and below water level. In addition, a GNSS RTK smart antenna was operated as a base station. PHASE 1 - CONDUCTING BATHYMETRIC SURVEY A bathymetric survey consists of three main steps: preparation, measurement, and data processing. Step 1. Preparation. Prior to the survey, as no GNSS RTK network was available, it’s necessary to install a GNSS base station, set up control points, and perform site calibration to establish a mapping referentially. For the measurement goals, we can set the route in the software in advance; then, the boat will be measured automatically along the route (what was made in this project), or we can use the remote control to operate the boat during the next step of this survey. Figure 1. The planning of the route for the autonomous navigation of the Apache 3 USV. Step 2. Measurement. In the process of measurement, the software located the points according to the prescribed route. The distance between the anchor points of the test line was encrypted according to the measurement proportion to ensure that there were points of convergence with the main test line within the specified range. Each inspection line was compared with the crossing points of the main survey line. Figure 2. The Apache 3 USV, a portable marine drone with a single beam echo sounder, is conducting a hydrographic survey. Step 3. Data Processing. The CHCNAV HydroSurvey 7 software, supplied with the Apache 3 USV, was used to manage raw data collection, mapping, positioning, real-time trajectory display, data processing, and coordinate systems. The software integrates data acquisition and post-processing functions. It supports standard GPGGA and SDDPT water depth data and DWG/DXF format, with layer editing, hiding, and display capabilities. Figure 3. Data processing in the HydroSurvey software. According to the different reservoir areas under different elevations, the corresponding storage capacity was obtained and processed. Figure 4. Underwater elevation and calculation of reservoir area and storage capacity. PHASE 2 - CONDUCTING AIRBORNE SURVEY As in the previous phase, there are three steps to conduct aerial surveys: preparation, measurement, and data processing. Step 1. Preparation. Before collecting scanner and image data with the unmanned aerial vehicle (UAV) carrying the LiDAR+RGB system (Alpha Air 450), installing a GNSS base station in an open sky near the project site was necessary. Depending on the model of the GNSS station used, aerial surveys can be performed in real-time mode or in post-processing mode by recording static data. Figure 5. The AlphaAir 450 Lidar (AA450) system with built-in IMU, GNSS, 3D scanner, and RGB camera. Step 2. LiDAR Data & Images Acquisition The AA450 LiDAR scanner features a one-touch workflow control system that allows any survey to be managed with a one-button press. When the aerial data for the project was collected, the CHCNAV CoPre software - a 3D laser scanning pre-processing software supplied with the AA450, was used to transfer the data to the computer via a USB-C cable. Step 3. Data Processing In the first step, the CoPre software was used to combine the raw laser data and the POS data to generate georeferenced point cloud data. In a second step, the raw image and POS data were combined to generate a digital orthometric model (DOM). The ground point cloud data was classified in the CoProcess reality capture post-processing software to generate the digital elevation model (DEM). Figure 6. The original laser point cloud data (left) and the colorized point cloud (right). Figure 7. The reservoir DOM (left) and DEM (right) after data processing. PHASE 3 – CALCULATING THE WATER RESERVOIR CAPACITY At this stage, the virtual model of the reservoir was created. The water level in meters and capacity in cubic meters were efficiently and accurately calculated and presented on the diagram. Figure 8. The 3D modeling of the value of available water compared to the current water level. Figure 9. Diagram of the reservoir’s water capacity. By using new technologies, such as LIDAR scanners, drones, and USVs, it is now possible to improve the level of accuracy and time spent on acquiring the reservoir's topography and calculating its storage capacity. As a result, survey costs are significantly reduced, and the efficiency of the long-term maintenance process is improved. With the reservoir's digital model, survey and mapping results can be enriched, and future developments can be simulated, monitored, and forecasted. ___ About CHCNAV CHC Navigation (CHCNAV) creates innovative GNSS navigation and positioning solutions to make customers' work more efficient.

Farmers' fieldwork in China results in higher earnings with CHCNAV technology
While improving profits may remain a challenge for the agricultural industry, there are some spectacular success stories around Tongliao City that are worth reporting. Located in the eastern part of Inner Mongolia, the town of Tongliao is an area rich in corn, green onions, peanuts, and other crops, where local farmers have recently achieved stunning success after integrating automated steering systems in their daily farming operations. CORN "Corn is the main food crop in Tongliao. In the past, people thought that corn planting could be not straight, and the errors caused by manual driving would not cause serious damage. However, in the last two years, farmers have started to use automated steering for seeding, and everyone has realized that it is much more efficient. It works very well, and yields have increased as well." said Mr. Liu, CHCNAV's distributor. Figure 1. A local farmer, Mr. Guo, and his corn field in Tongliao. It was the first year that Mr. Guo used an auto-steering system. 2,000 acres of land were easily cultivated, and he is full of praise for the productivity that the CHCNAV solution has brought him. "Farming with the auto-steering system is particularly accurate and efficient. For example, previously, I tried to sow at night, which was really difficult, and the lines turned out to be very squiggly. Now, with the CHCNAV system, I can easily work at night and maintain a very symmetrical distance between the lines, so the crops get good light transmission and ventilation and therefore better growth," said Guo. GREEN ONION Figure 2. CHCNAV’s dealer, Mr. Liu, and green onion field in Tongliao. "Tongliao green onion is growing well this year; many farmers say that the net profit of one acre of green onion is substantial, it will be an excellent harvest year," shared local dealer Liu. "Green onion ridging and furrowing require serious technical skills. Previously, we drove manually, and the lines were uneven, which is detrimental to the hilling later because it affects crop growth and harvest. Now people use autosteering, which makes everything less complicated, including hilling and harvesting. As a result, production has increased, and farmers have started to earn more money!" PEANUTS Figure. 3. Mr. Jiang, a peanut farmer in Tongliao, and his crop. Mr. Jiang is the local peanut grower, owning more than 1,200 acres of land. In the past, the most serious difficulty he encountered was following the path when planting and inverting peanuts. "Now, with the CHCNAV autosteer, the ridges are very straight, making it much more convenient to harvest. The ridge spacing is under control, the weeding process and ventilation work well, the peanut yield has increased, and we have achieved higher earnings," said Mr. Jiang. Whether it is a new or old tractor or other farm vehicles, a small or large farm, corn or onion, many farmers in Tongliao have enjoyed the benefits of CHCNAV's NX510 automatic steering kits and made their farming business more efficient throughout the farming seasons. ___ About CHCNAV CHC Navigation (CHCNAV) creates innovative navigation and positioning solutions to make customers' work more efficient.

Manage and Develop Mining Infrastructure Efficiently with CHC Navigation
CHCNAV is a global provider of geospatial technologies to optimize mining operations. CHC Navigation (CHCNAV) creates innovative navigation and positioning solutions to make customers' work more efficient. CHCNAV products and solutions cover multiple industries such as geospatial, machine control, construction, agriculture, and marine. With a presence across the globe, distributors in more than 120 countries, and more than 1,500 employees, CHC Navigation is recognized as one of the fastest-growing companies in geomatics technologies. Nowadays, mining companies are often under extreme pressure to reduce costs, increase efficiency and improve safety performance while maintaining high production quality. There are no easy solutions, but it is clear that technology is making a significant contribution to the mining operation. Digitizing mining and quarrying sites with CHCNAV's mapping systems helps optimize production processes. The use of appropriate and reasonably priced surveying technology, combined with adequate professional training of personnel, makes the operation of mining companies more efficient, strengthening the overall production process and thus increasing revenues. Although the mining industry differs from country to country, the implementation of new technologies in the mining sector frequently results in a series of difficulties. Below, we explore 3 common challenges the mining industry currently faces in the widespread adoption of advanced technologies in 3D mapping and GNSS surveying. 1. High-tech solutions, such as laser scanners, unmanned aerial systems (UASs), advanced positioning systems, rugged field data controllers and tablets, surveying and mapping, and data processing software, are often associated with high costs and may therefore be considered out of reach from a financial point of view. In addition, mining companies may have difficulties recruiting highly qualified employees as they prefer to use up-to-date equipment such as GNSS receivers, photogrammetric drones, and Lidar 2. Harsh operating environments and remote, hard-to-reach locations of sites have an effect on machinery and equipment that must withstand the tough conditions of the reality in which they operate. Mining companies need durable, rugged equipment with strong dust and water protection that can survive a wide range of operating temperatures. 3. Existing outdated survey tools may be technologically difficult to replace in a short period of time without influencing operation processes. Moreover, veteran employees may be reluctant to learn to use new equipment and different software, such as in the case of switching from theodolites to GNSS technology. WHAT PRACTICAL SOLUTIONS DOES CHCNAV PROVIDE GLOBALLY TO MINE SITE MANAGERS? 1. CHC Navigation delivers affordable, up-to-date, and high-quality technologies that meet the specific needs of mines and quarries. Efficient 3D Mappers and Scanners Collecting, processing, and maintaining high-density 3D geospatial data of mines with mobile mapping solutions, like UAVs (drones) and 3D LiDAR scanners, is highly cost-effective. Light Laser Detection and Ranging (LiDAR) is one of the most cutting-edge technologies in the field of surveying and mapping today. Installed on a drone for mining surveys, it measures the three-dimensional coordinates of the terrain as dense point clouds to generate a high-precision digital terrain model (DTM). Aerial surveying eliminates safety concerns for on-site surveyors, and it takes only minutes to hours to complete the measurement of the entire site, significantly improving production efficiency. Figure 1. Mining site point cloud with the RGB colorization made in CoPre Software; the survey was done with the AA450 lidar scanner and BB4 UAV, the CHCNAV's mobile mapping solutions. Robust and Reliable Land Surveying Instruments Surveying in the mining industry serves a critical function in providing essential information to all the other mining disciplines.

GNSS Continuously Operating Reference Stations (CORS) provide real-time navigation services but also a solution for mine subsidence monitoring and hazard early warning systems. Subsidence-related accidents are a major concern for the safety of mining sites. The implementation of GNSS monitoring techniques proves to be a crucial element, especially in mining sites located in areas with a high risk of geological disasters. Figure 4. CHCNAV’s GNSS reference station installed with a choke-ring antenna (CORS) in Laos GNSS RTK receivers and sensors, field controllers and tablets, machine control systems, GNSS RTK networks, Unmanned Aerial Vehicles (UAVs or ‘drones’), and LiDAR scanners are all the solutions CHCNAV provides to help to mine and engineering companies increase their productivity. 2. The IP67 (water and dust protection) certification level, multiple power sources, and the ruggedness of the CHCNAV products provide maximum confidence in their daily use and drastically reduce hardware downtime. The mining solutions from CHCNAV are ready to meet the requirements of the most demanding application. For example, the CGI-610 GNSS/INS system has IP67 dust and water resistant certification and industrial-grade power management integrated circuit guarantees reliable and consistent operation in the harshest environments. It is also vibration and shock resistant and is protected against electrostatic discharge. Another example is the P5 GNSS geodetic reference station, which supports dual external power inputs to ensure a stable and continuous electrical supply. The built-in high-capacity 17,000 mAh battery provides up to 20 hours of non-stop backup operation in the event of an external power outage. Its advanced power supply ensures uninterrupted operation 24 hours a day, 7 days a week, with continuous status information on its control screen and the option of remote monitoring of power supply conditions, network status, firmware version, etc. It is also IP67-rated water and dust resistant to withstand challenging conditions at installation sites, reducing potential downtime due to moisture or dust ingress. 3. With CHC Navigation, obsolete surveying systems can be replaced easily and seamlessly without affecting production processes. The adoption of GNSS technologies for new users will lead to the simplification of work processes, and systematic training sessions with field operators will result in increased productivity and a rapid return on investment. The integration of GNSS+Inertial technologies into GNSS smart antennas allows field crews to survey points without the need to perfectly level the survey range pole, making the surveying task even more reliable and easy. Software development also plays an important role in new technology uptake by enabling workflow automation: safety checklists for drones, codification of topographic surveys for optimal data processing with third-party CAD software, and more.

3D Bathymetry via USV-the Application Case Published in Sea Technology
USV with Multibeam Echosounder for Shanghai Bridge Survey The Donghai Bridge, located in Shanghai, China, is a key component of the Shanghai International Shipping Center’s deepwater port infrastructure. Conducting underwater surveys of the bridge piers’ conditions for maintenance purposes is an operational challenge. The bottom of the bridge piers is immersed in water and can be eroded by the action of sand and gravel. Hydrodynamic scour caused by rapid water flow can create scour holes and compromise the integrity of the structure. The solution selected for the Donghai Bridge survey project comprises an unmanned survey vessel, the APACHE 6 of CHCNAV, carrying a NORBIT iWBMS STX multibeam echosounder. Figure 1. The Apache 6 USV from CHC Navigation (the latest model). When conducting multibeam bathymetric surveys with an unmanned surface vessel, marine survey professionals highlight three major points of concern: How secure is their investment given the cost of multibeam echosounders? Does the USV offer sufficient flexibility to handle a variety of bathymetric survey scenarios? What about the final accuracy of the high-resolution 3D bathymetric survey? Figure 2. The bridge section piling data acquired by Apache 6 during the survey. During underwater terrain mapping, marine survey professionals often need to map dense underwater structures, such as bridge piers, as in the survey case in Shanghai. One of the main problems encountered is how to survey the topography behind the piers and the internal topography of the dense structures. When it is difficult to achieve this with traditional crewed boats, hydrographers now have the option of deploying USVs. USVs reduce survey time, improve work efficiency, and produce high-resolution 3D data to meet the requirements of the most demanding marine infrastructure projects. The CHCNAV APACHE6 USV is an innovative and fully integrated solution for 3D bathymetric surveys, underwater objects, and offshore construction.
