Sensors for autonomous platforms

AUV, ROV, & Autonomous Platforms Sensors

Sensors integrated into AUVs, ROVs, and autonomous platforms allow autonomous exploration of both ocean and freshwater systems. These platforms expand research reach, reduce operational costs, and provide high-resolution spatial coverage for scientific and industrial missions.
