Multi-beam detection system -M400S
M400S is a new generation of integrated, miniaturized, intelligent portable multi-beam sounding system with high precision, easy installation and calibration-free characteristics. It is compact, intelligent and lightweight, with low power consumption. One person can easily measure and meet the needs of rapid measurement anytime and anywhere; it is suitable for USV platform installation, especially unmanned ship system, and expands diversified operations, which fully reflects the industry’s convenient and efficient development concept. M400S has excellent measurement performance, which ensures measurement accuracy while easily meeting the needs of a large number of customer groups for lightweight operations.
Product Features
Regular shape, easy to integrate
The sonar probe size of M400S is a standard diameter of 22cm, which is consistent with the size of most ADCPs. Most hydrographic survey ships can be directly integrated and used without modification. It is compatible with a variety of mainstream software, making integration more convenient. The transducer adopts an integrated regular shape design, suitable for single-body and trimaran unmanned ships.
Easy to set up, ready to measure
In order to improve the integration of the entire system, auxiliary measurement sensors such as surface sound velocity meter, attitude meter and GNSS are all built into M400S. Users do not need to purchase them separately, and installation errors are also reduced. It can be said that it is truly All-in-One and “ready to measure”.
Automatic measurement, no intervention
M400S provides fully automatic measurement mode, fully automatic threshold, range, and signal parameter settings, and measurement does not require manual intervention, which greatly reduces the professional requirements for operators, and non-professional staff can also easily get started.
Integrated design, powerful functions
The M400S consists of only two parts: the sonar probe and the deck unit. The surface velocity meter, high-precision attitude meter, and satellite positioning system are integrated together. All measurement data can be output in a standardized manner. It can measure underwater terrain and provide navigation information for unmanned ships.
