China Youth Daily Client News (Gu Xuejinsheng, China Youth Daily, China Youth Network reporter Meng Peipei) On October 12, "Sun Wukong", who is over 2 meters tall, appeared at the exhibition halls of universities and research institutions at the 2023 World Navigation Equipment Conference and World Navigation Equipment Expo, attracting many visitors to stop.

This is the "Wukong" unmanned underwater vehicle developed by Harbin Engineering University. At 15:47 local time on November 6, 2021, it set a world record for an unmanned cableless submersible diving depth of 10896 meters in the Challenger Abyss of the Mariana Trench, just like Wukong, who bravely explored the Dragon Palace, operating autonomously at 10000 meters underwater and collecting precious underwater images and videos of the abyss.

Not long ago, with the 13th Arctic Ocean Scientific Expedition Team of China, I successfully completed the scientific research mission on the "Xuelong 2" polar exploration icebreaker, and the "Xinghai 1000" polar exploration unmanned submersible developed by Harbin Engineering was also exhibited. The "Xinghai 1000" spacecraft set sail in the Arctic, verifying key technologies such as high-latitude underwater navigation, underwater acoustic communication, and precise control of underwater navigation in the polar region. It has accumulated valuable experience for submarine scientific research operations in high-risk areas and extremely harsh environments in the polar region.

From October 12th to 15th, the 2023 World Navigation Equipment Conference was held in Fuzhou, with over 600 companies from the Fortune 500, large state-owned enterprises, and navigation equipment assembly manufacturing enterprises in the field of navigation equipment participating. Harbin Engineering has presented 66 achievements and 18 physical models generated from decades of scientific research and exploration, totaling nearly 100 achievements, at the exhibition.

The "Wukong" is surrounded by various "highly skilled" underwater vehicles from Harbin Engineering, ranging in size from tens of tons to small enough to carry on their backs. These underwater vehicles can reach any seabed in the world, engaging in various tasks such as collection, detection, grasping, communication, and so on, from independent work to collaborative efforts in groups... From China's first underwater intelligent robot in the 1980s to today's "Wukong", "Weilong" series, and "Orange Shark" The multi-purpose underwater operation ROV robot, Tianxing No.1 and other underwater vehicles have become an indispensable and important technical force in accelerating the construction of China's marine unmanned equipment system through decades of scientific research on underwater robots by the Harbin Engineering Corporation.

On the other side of the exhibition area, a cool operating platform has attracted the attention of many visitors. It can display the wind speed, direction, wave energy and other environments encountered by the ship in real-time, ensuring the stability of the ship at sea. This is the three redundant dynamic positioning system, known as the "fixed ship divine needle", developed by the school's scientific research team. It is the highest level ship dynamic positioning system with independent intellectual property rights in China.

The relevant staff of the school introduced that since 1982, the school's scientific research team has been the first in China to develop ship dynamic positioning technology. After more than 30 years of technical research, they have successfully developed a full series of DP1, DP2, and DP3 dynamic positioning control system products. Among them, DP2 and DP3 are the only products in China that have obtained CCS type approval certificates. The product technical indicators have reached the international advanced level, and the product price is more than 30% lower than that of similar foreign products. This has broken the technological blockade and provided a solid technical guarantee for China's marine engineering equipment to enter the deep sea.

Ten thousand meters of deep sea, vast and boundless. It is almost impossible to determine a location in the vast deep sea, or even find a target from the dark and complex seabed without light or signal. But for humans to advance into the deep sea, this is an indispensable key technology.

The deep-sea high-precision comprehensive positioning system exhibited at this exhibition has undergone several transformations of domestic underwater acoustic positioning technology from "learning to walk" to "following", and then to today's "parallel running". This system has the capabilities of underwater wide area positioning and tracking, needle in a haystack precise positioning of 10000 meter underwater markers, and multi node interconnected deep-sea search and docking guidance. It has achieved sub meter level positioning of 10000 meter deep sea for the first time internationally, equipped on the "Wukong" and providing high-precision positioning support for China's third-generation manned submarines "Jiaolong", "Deep Sea Warrior", and "Struggler" deep-sea operations.
