Overview

Key Application Scenarios


Unmanned Underwater Vehicle (UUV/ROV/AUV) Integration

The MiniUAC-850A provides critical support for navigation collision avoidance, target detection, and underwater operations for unmanned platforms such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs). It directly outputs high-definition image data of obstacles and targets ahead of the platform, ensuring safe navigation and reliable operational support for complex underwater missions.

Diver Operation Support

The MiniUAC-850A Forward-Looking Sonar (Diver Edition) is designed with a compact footprint and neutral buoyancy in water, enabling seamless integration into diver gear. It delivers high-resolution imaging of underwater targets, providing divers with real-time situational awareness and effective operational support for underwater inspection, search, and rescue missions.
