Stingray Ⅱ AUV

The Stingray Ⅱ AUV is equipped with a variety of underwater acoustic, video and hydrological sensors, and has carried out a number of submarine topography mapping and water observation tests in Haima cold springs and other sea areas, providing technical support for marine scientific research, environmental observation and underwater defense.

In response to the need for long-term observation of the seabed, Stingray Ⅱ completed 18 days and 27 continuous underwater docking and wireless power/signal transmission tests.

Facing typical application requirements such as underwater photography, seabed surveying and mapping, and water quality observation, the Stingray Ⅱ AUV provides a variety of working modes such as fixed-depth navigation, fixed-altitude navigation, hovering, pre-programmed tracks, and intelligent trajectory planning.

Deep-sea landing vehicle

The Deep-sea landing vehicle is a novel crawler-type investigation platform with autonomous working ability, funding by The Major Scientific and Technological Projects of Hainan province. Deep-sea landing vehicle has a maximum working depth of 4,500 meters, with a weight of 1.8 tons, carrying deep-sea sensors such as a current meter, 4K camera, CTD and multi-parameter water quality meter. It can conduct continuous sampling for 10 kilometers or 6 months. During sampling, data can be regularly transmitted back to the shore-based terminal via self-elevating beacons for remote monitoring. With special payloads, it can carry out sampling operations for seafloor sediments and microbiota. Deep-sea landing vehicle is a mobile, multi-functional scientific deep-sea platform with a wide range of motion ability, which can provide support for deep-sea scientific investigations.

Deep-sea archaeology AUV

The Deep-sea archaeology AUV is an autonomous exploration platform designed for fine investigation of seabed targets, and the development is supported by the National Key Research and Development Program of China. The deep-sea archaeology AUV can operates at a maximum depth of 1000 meters, the cruising speed ranges to 2 knots, and underwater operating time can be up to 15 hours. The external dimensions of the deep-sea archaeology AUV are φ350 mm*3.8 m, and the weight in air is about 260 kg. Equipped with side-scan sonar, forward-looking sonar and cameras, the deep-sea archaeology AUV is capable of conducting wide-area rapid search and close-range fine detection of targets on the seabed, obtaining wide-area acoustic detection data and high-resolution video images of the seabed area. The deep-sea archaeology AUV can provide support for deep-sea archaeological exploration, underwater investigation, specific target search and identification, and have broad application potential.
