Introduction
TD-MS400U is an ultra-miniature and highly integrated all-in-one multibeam echo sounder, specially developed for small-sized unmanned surface vehicle (USV) and underwater unmanned device survey applications. It fully integrates the surface sound velocity meter, attitude indicator, GPS, etc. Meanwhile, its various interfaces are developed externally, supporting the synchronous work with other devices.
Features
●Highly integrated functions: It integrates the high-precision satellite positioning system, high-precision attitude indicator and sound velocity meter, which can realize the calibration-free underwater terrain survey and provide the position navigation information for unmanned surface vehicles.
●Full-automatic measurement: Full-automatic measurement free of calibration, parameter adjustment and manual intervention, suitable for all kinds of unmanned platform integration applications.
●Low power consumption & light weight: The whole device power consumption is as low as 70W and the weight is 7.5kg. It is easy to install and can be integrated into all kinds of unmanned surface vehicles such as kayaka, catamaran and trimaran.
●Support for extended applications: Standard attitude, position, time and synchronization data output with independent and extensible network interfaces, support for extended 3D laser scanner, and support for ADCP joint survey, multi-beam echo sounding and side-scan sonar joint survey.
