SatLab Marine And Water Resources Jarnbrotts Prastvag 2 SE-42147 - Vastra Frolunda Gothenburg, Sweden

CONTENTS PREFACE The boundless ocean has surging power and profound beauty, we revere her, and we explore her. Light can only penetrate a few meters underwater, while sound waves propagate at a speed like 1500m/s in the water to unveil the water covering the earth for people. Over a hundred’s years ago, people of wisdom invented sonar to emit sound waves. After a century of development, sonar technology has become more sophisticated and our exploration of water is growing rapidly! We may not fully understand the ocean yet, but we see the widest range of real needs in marine and water resources....

GNSS Receiver About GNSS Receiver • 1408-Channel Signal Tracking; GPS L1/L2/L5, GLONASS L1/L2, BDS B1/B2/B3, Galileo E1/E5 and L-Band Capability GNSS Receivers are the core product for satellite positioning. They convert signals from visible satellites into a position on earth. The amount of visible satellites is dependent on the number of constellations the receiver is compatible with, such as GPS, GLONASS, GALILEO, and BDS. The Njord is a SatLab next-generation multi-GNSS, multi-frequency, position and heading receiver designed specifically for marine and construction applications with the capability...

Dual-Frequency SBES About Echo Sounder For many small waters and shallow waters, the single beam echo sounder (SBES) survey method is still the best choice. From fish finders to bathymetric instruments, SBES uses the simplest principle - by calculating the sounder velocity and the interval between pings and echoes to get the depth of water, the simplest installation method, the most affordable price, and occupies a place in the hydrographic survey. Rugged Industrial Platform Multiple I/O Interfaces ES-224+SLHydro Sounder 17-inch Large Tempered Glass Screen SBES has a single frequency and dual frequency....

HydroScan Side Scan Sonar About Side Scan Sonar Multiple Frequency Available Side scan sonar also referred to as side-looking sonar and side-imaging sonar is a type of sonar system that is usually towed aft of a survey vessel and emits sonar pulses to the water bottom. Side scan sonar is used to effectively create images of large areas under the water. The sound frequencies used in side scan sonar usually range from 100 to 500 kHz; higher frequencies yield better resolution but less range. Side-scan image interpretation is also a necessary skill when using side-scan. Multiple Internal Sensors...

Acoustic Doppler Current Profiler About ADCP Multiple Built-in Sensors Water flow can be measured in many different ways, such as rotating-element current-meter, float run method, slope-area method, and now we use acoustic Doppler devices to quickly and accurately measure water flow. Acoustic Doppler devices use sound waves and the Doppler effect to measure velocity fluctuations underwater. The main Doppler techniques used in ADCP are water tracking - measuring the movement of the water relative to the ADCP, and bottom tracking - measuring the movement of the river bottom or seabed relative to the...

An Android-Powered USV System for Bathymetric Surveys About USV USVs (Unmanned Surface Vehicles) are widely used in hydrographic surveys, environmental monitoring, and water search and rescue. Among them, hydrographic surveying is the most used and developed field. When a hydrological survey is facing many unknown waters, it usually takes a long time navigation and requires high accuracy, which poses great challenges to the safety and health of surveyors. The hydrographic survey USV combines various complex systems to offer users the simple and efficient operation mode. With double hull design,...
