It captures highly accurate depth data, seabed morphology, and surface texture, making it essential for large-scale hydrographic operations. MBES is commonly used for nautical charting, offshore construction planning, pipeline route surveys, navigational safety assessments, dredging volume estimation, and detailed 3D seabed modelling.

Side Scan Sonar is a high-resolution underwater imaging system that uses high-frequency acoustic pulses to create detailed visual representations of the seabed or riverbed. It can detect submerged objects, underwater structures, wrecks, debris, and variations in seabed texture with exceptional clarity. This system is widely applied in obstacle detection, navigation safety surveys, subsea cable and pipeline pre-installation assessments, marine forensic investigations, and geophysical seabed mapping. With its broad coverage and high-resolution imagery, Side Scan Sonar is an essential tool for engineering projects, safety operations, and marine environmental monitoring.

A Sub-Bottom Profiler is a marine geophysical system that uses low- to mid-frequency acoustic pulses to penetrate beneath the seabed or riverbed and produce detailed subsurface profiles. It reveals sediment layers, geological structures, buried objects, and stratigraphy, supporting applications such as geotechnical studies, subsea cable and pipeline route planning, seabed stability assessments, dredging investigations, and marine research. With its deep penetration and high-resolution imaging capabilities, the Sub-Bottom Profiler delivers essential insights into subsurface conditions that cannot be obtained through conventional hydrographic instruments.

A Marine Magnetometer is a high-sensitivity geophysical instrument used to detect variations in the Earth’s magnetic field, allowing the identification of buried ferrous objects on or beneath the seabed. It can locate pipelines, cables, anchors, submerged equipment, UXO, and shipwrecks – even when buried under sediment – making it essential for utility detection, UXO surveys, marine archaeology, pipeline and cable route assessments, and large-scale geophysical mapping.

An Acoustic Doppler Current Profiler (ADCP) is a high-precision instrument that measures water current speed and direction throughout the water column using acoustic pulses and the Doppler effect. It provides detailed vertical or horizontal current profiles for applications such as tidal studies, long-term current monitoring, river flow analysis, coastal engineering, flood mitigation, and hydrodynamic modelling, delivering essential data for navigation safety and coastal development planning. With the ability to measure multiple layers of water simultaneously, the ADCP provides essential data for navigation safety, flood mitigation, engineering studies, and coastal development planning.

A Submerged Tide Gauge is a high-precision instrument that records continuous water level changes using a pressure sensor installed on the seabed, riverbed, or lakebed. Unaffected by waves or surface disturbances, it provides stable and accurate data for tidal studies, long-term water level monitoring, marine structure design, flood management, hydrodynamic modelling, and coastal environmental research.

A 1-Liter Water Sampler is a precision tool used to collect uncontaminated water samples at specific depths in rivers, lakes, reservoirs, and marine environments. Its secure closing mechanism preserves true water column conditions, making it essential for water quality testing, environmental monitoring, pollution assessments, and scientific studies across hydrographic, governmental, and environmental sectors.

A 1KG Grab Sampler is a sediment sampling tool designed to efficiently collect surface seabed or riverbed material while preserving true surface conditions. Its secure mechanism prevents sample loss during retrieval, making it ideal for geotechnical surface investigations, sediment quality monitoring, pollution assessments, benthic studies, dredging management, and environmental impact evaluations.

GNSS (Global Navigation Satellite System) equipment provides centimetre-level positioning accuracy for both marine and land surveying. In hydrographic work, it integrates with systems like single beam, multibeam, side scan sonar, and ADCP to deliver stable real-time coordinates even during vessel movement. On land, it supports topographic mapping, setting-out, structural monitoring, boundary surveys, and geodetic control. Modern GNSS receivers use multi-constellation signals (GPS, GLONASS, Galileo, BeiDou) and advanced methods such as RTK, PPK, and dual-antenna heading to ensure high accuracy, stability, and reliability.

A Water Temperature Logger is a high-precision instrument that continuously records water temperature using sensitive thermistor or digital sensors. Compact, waterproof, and pressure-resistant, it can be deployed on buoys, structures, or directly on the riverbed or seabed. Its data supports water quality assessments, hydrological modelling, ecological studies, and environmental impact monitoring across rivers, lakes, reservoirs, estuaries, and marine environments.

Drone-based LiDAR is a high-precision aerial mapping technology that uses laser sensors to generate accurate 3D models of the Earth’s surface, even through dense vegetation. Mounted on UAVs, it captures millions of points per second, enabling fast, detailed mapping of complex or rugged terrain. With centimetre-level accuracy and rapid coverage, Drone LiDAR supports engineering surveys, volumetric calculations, topographic mapping, urban planning, forestry studies, landslide and flood risk assessments, and long-term terrain monitoring – offering reduced field time, lower costs, and high-density datasets for advanced analysis.

Single Beam by USV integrates a Single Beam Echo Sounder with an unmanned surface platform to collect precise bathymetric data safely and efficiently without placing operators on the water. Ideal for shallow, hazardous, narrow, or hard-to-access areas, the system uses autonomous navigation, GNSS/RTK positioning, and high-precision depth sensors to deliver reliable data for rivers, lakes, reservoirs, and coastal zones. It reduces operational risk, lowers costs, and enhances efficiency for routine monitoring, engineering studies, and small to medium-scale hydrographic mapping.
