On February 15th, an incredible unmanned surface vessels (USV) formation was staged at the Hong Kong-Zhuhai-Macao Bridge, one of Zhuhai's landmarks. The Bridge, which has just been completed and is the longest sea- crossing bridge in the world, connects Zhuhai to Hong Kong and Macao. This night, the Bridge became the most spectacular background, a 7.5-meter-long "Lookout" marine unmanned vessel led 80 1.6-meter long unmanned vessels, lined up into an "arrow" through the Hong Kong-Zhuhai-Macao Bridge.
The USV formation then compiled into the Chinese word “启航” which means ‘set sail’ and headed for the door of "the new era" made up of drones in the sky. The lights and fireworks illuminated the ocean dream of the Chinese nation. The show has foreshadowed the unmanned technology development strength of China and is now moving to a new era with determined steps.
Before the show, the global experience of multi USVs cooperative operation is only from the US military, but the number is only 13 USVs on public record, and has never done any external performances. The performance on the CCTV spring festival gala is the first in the world to achieve the massive number of USVs work together and present a spectacular show in world-class.
This show was the first appearance of the multi-vessels collaboration from Oceanalpha. From the start of the performance task, nearly a hundred of unmanned vessels have been produced and turn into “water dancer" by Collaborative programming in two months. Simultaneously operating 81 USVs is unprecedented in the industry. The sea condition on site is SS-2 to SS-3. Faced with environmental disturbances such as wind and waves, Oceanalpha team adopted robust and adaptive control technology to ensure smooth control of the fleet. High-precision GNSS and Integrated inertial navigation, combined with RTK technology, ensures the precise trajectory of USVs. In addition to controlling and navigating formations, Oceanalpha team adopted a tracking algorithm based on the virtual leader combined with the path to realize formation-conversion and automatic collision avoidance of a massive number of vessels.
"This is not just a performance, it is a tribute to future marine survey and exploration by mankind, especially the start of new technological methods in geophysical survey. In the near future, unmanned vessels will be more efficient to play its own technical characteristics, and gradually get rid of the existing 'ship + mission payload' of the traditional mode of operation, with a new payload, new methods of operation, high-density cluster collaboration in an unprecedented way to change the entire industry and extending to more industry applications. " CEO of oceanalpha Zhang Yunfei said.
Multi types of USV from Oceanalpha
Oceanalpha is the first high-tech enterprise specializing in unmanned surface vessels manufacture and development in China. Oceanalpha has now formed the environmental measurement, marine surveys, security, military and unmanned freight transport five business segments and plays an leading role in unmanned technology industry.
