Pelagix Highlights Unmanned Underwater Vehicles at China International Defense Electronics Exhibition

The 14th China International Defense Electronics Exhibition was held at the China National Convention Center in Beijing. The event brought together new technologies, advanced applications, and industry trends in electronic information and intelligent equipment.

At the exhibition, surface and underwater unmanned equipment also drew interest.Pelagix, the brand of Sanya Poseidon Ocean Technology Co., Ltd., presented its focus on advanced unmanned underwater vehicles and deep-sea intelligent equipment.

Pelagix Focuses on Deep-Sea Intelligent Equipment

Sanya Poseidon Ocean Technology Co., Ltd. is a high-tech enterprise based in the Sanya Yazhou Bay Deep-Sea Equipment Industrial Park. Operating under the Pelagix brand, the company specializes in the R&D, manufacturing, sales, and technical services of advanced deep-sea intelligent equipment.

Its core focus is the development and market application of Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs). These systems are built to support ocean exploration, marine engineering, underwater inspection, and subsea operations.

As the demand for safer and smarter marine tools grows, unmanned underwater vehicles are becoming a key part of modern ocean work. They help users reduce risk, collect data more efficiently, and carry out tasks in complex underwater environments.

Unmanned Underwater Vehicles on Display

At the Sanya Poseidon Ocean Technology Co., Ltd. booth, multiple unmanned underwater vehicles of varying sizes were on display. These vehicles showed the company’s technical direction in underwater detection, seabed survey, marine research, and inspection applications.

According to the company, Pelagix AUV and ROV products are designed for deep-sea exploration, marine engineering surveys, scientific research, seabed mapping, underwater inspection, oceanographic research, dam inspection, and subsea operations.

Its AUV systems feature depth capability, long endurance, and modular payload integration. Meanwhile, its ROV products support subsea inspection, environmental monitoring, and light pipeline maintenance.

Together, these platforms provide flexible solutions for different underwater missions. For example, an AUV can carry out wide-area survey tasks, while an ROV can support close-range inspection and real-time observation.

Meeting the Needs of Modern Marine Operations

“Underwater unmanned equipment is playing an increasingly important role in marine surveys, seabed mapping, underwater inspection and offshore engineering operations. As application scenarios become more complex, users are placing higher requirements on depth capability, endurance, modular payload integration and intelligent operation,” a company representative said.

This reflects a clear industry trend. Marine users now need equipment that can work in deeper waters, stay underwater for longer periods, and carry different sensors for different missions.

For seabed mapping, underwater vehicles can follow planned routes and collect useful data over large areas. For marine engineering, they can support early survey work and later asset inspection. For dam inspection, they can help check underwater structures while reducing safety risks for workers.

In addition, underwater vehicles are also useful for oceanographic research, environmental monitoring, submarine cable inspection, and offshore infrastructure support.

Intelligent Technologies Behind Pelagix Systems

Pelagix also focuses on key technical fields that support the future of underwater operations. These include AUV autonomous navigation and SLAM systems, underwater automatic small-target recognition based on optical and acoustic methods, AUV underwater docking systems, AI large foundation models for deep-sea mesoscale eddy forecasting, UUV entanglement identification and cut-and-clear systems, and multi-AUV collaborative survey and swarm control systems.

These technologies are important because underwater environments are often difficult to predict. Light is limited, signals can be weak, and operating conditions may change quickly. Therefore, intelligent navigation, target recognition, and cooperative control can help underwater vehicles complete missions more safely and efficiently.

For users, this means better data, lower operational risk, and stronger support for complex marine tasks.

Modular Payloads for Flexible Missions

Different underwater missions need different tools. A seabed mapping task may require sonar. A pipeline inspection task may need cameras and lights. A scientific research mission may need special sensors.

Therefore, modular payload integration is an important feature for modern AUV and ROV systems. It allows one platform to support many tasks. It also helps users adjust equipment based on actual project needs.

Pelagix AUV systems are designed with modular payload integration, helping users carry out marine surveys, underwater inspection, and scientific research with greater flexibility.

Future Development of Underwater Vehicles

How to achieve lightweight design and longer underwater endurance while maintaining hull strength remains a future development direction, the company representative said.

This is also a key challenge for the unmanned underwater vehicle industry. A lighter vehicle can improve efficiency and reduce power use. However, it must still be strong enough for deep-sea pressure and demanding underwater conditions.

Longer endurance is also important. With longer operating time, AUVs can cover larger areas and reduce the need for frequent recovery. At the same time, reliable hull strength helps protect the vehicle during deep or complex missions.

As a result, future underwater systems will likely focus on stronger materials, smarter power management, improved navigation, and more flexible payload options.

For Pelagix, as marine industries expand and underwater missions become more complex, AUVs and ROVs will play a greater role in survey, inspection, research, and engineering work.

With its focus on deep-sea intelligent equipment, Pelagix continues to support the next stage of ocean technology through reliable unmanned underwater vehicles and integrated technical services.
