How does an AUV works?

An Autonomous Underwater Vehicle (AUV) operates by using a combination of onboard sensors, navigation systems, and software to navigate and perform tasks underwater without human intervention. It typically employs GPS for surface navigation and inertial navigation systems or depth sensors while submerged. AUVs can collect data on oceanographic conditions, marine life, and underwater topography, and they are programmed to follow pre-defined paths or respond to environmental conditions. The gathered data is stored onboard and transmitted back to researchers once the vehicle surfaces.
