The FLS800D has a maximum horizontal field of view of 130°, providing customers with the largest possible exploration area.
The VST-800D employs advanced digital signal processing, image enhancement, and target detection technologies, offering ultra-high-definition resolution at the millimeter level. It is capable of detecting underwater targets, providing collision avoidance navigation, and obstacle detection. The sonar is also characterized by its small size, light weight, and high integration, making it particularly suitable for installation on small unmanned platforms with limited space. It can also be used as a handheld navigation sonar for divers.

The UBD-1000 Ultra-Short Baseline (USBL) Underwater Beidou Positioning and Communication System is specifically designed for tethered underwater robots (ROVs) and untethered autonomous underwater vehicles (AUVs). It enables high-precision positioning of underwater targets and stable wireless two-way communication between surface and underwater platforms.

This product adopts state-of-the-art broadband spread spectrum technology and target tracking algorithms, allowing simultaneous real-time positioning, tracking, and communication of multiple underwater targets. This capability helps users establish a multi-node, stereoscopic underwater positioning and communication network. The multipath effect suppression algorithm, developed for challenging shallow-water environments, significantly reduces positioning drift and improves positioning effectiveness. The anti-Doppler effect compensation algorithm ensures stable positioning and communication for surface and underwater platforms (e.g., AUVs) during high-speed dynamic navigation. Additionally, the system features a compact size, lightweight design, and high level of integration, making it particularly suitable for installation on underwater vehicles with limited space, as well as for diver-held navigation sonar platforms.

Working Principle:

The underwater acoustic modem encodes text, voice, and image data into digital signals and converts them into acoustic signals. These signals propagate through water to the receiving transducer, where they are converted back into electrical signals. After decoding, the original information—such as sound, text, and images—is restored.
