With the efforts of the project team, China’s satellite tracking buoy technology has made major breakthroughs. It successfully developed the Beidou satellite precision positioning and two-way communication profile buoys, and it was first put into use in the Argo real-time ocean observation network in 2015. At present, China has established the “Beidou Profile Buoy Data Service Center†that integrates Beidou satellite precision positioning and two-way communication profile buoy technology in Hangzhou, and has constructed a Buoy profile buoy data automatic reception with automatic, batch, and operational buoy data reception capabilities. The real-time marine monitoring network system for decoding, correction, quality control and sharing services meets the basic research and operational applications in China's marine and atmospheric scientific fields and the requirements for data exchange and sharing proposed by the international Argo plan.
This breaks the limitation that China can only rely on the introduction of foreign cross-section buoys to construct a real-time ocean observation network, realizes the breakthrough of the “zero†breakthrough for China’s marine observation instruments and equipment for the international large-scale maritime cooperation investigation program, and expands the service field of Beidou satellite navigation system. It provides an important guarantee for the construction of the Argo Ocean Observing Network covering the "Maritime Silk Road" region. It has important strategic and practical significance for safeguarding China's maritime rights and interests and realizing the dream of a strong ocean.
The Argo (Global Ocean Real-Time Observing Network) project was launched in 1998 as a global ocean observation pilot project. It aims to quickly, accurately and widely collect seawater temperature and salt in the upper oceans of the world through satellite tracking buoys deployed in the global ocean. Profile data are used to improve the accuracy of climate predictions and effectively prevent threats to humanity caused by increasingly severe global climate disasters (such as hurricanes, cyclones, typhoons, ice storms, floods, and droughts). As of March 2016, China has deployed about 350 Argo profile buoys in the Pacific Ocean and the Indian Ocean, and there are still more than 160 normal operations at sea. The Argo real-time ocean observation network has basically been built in China.
