Zhejiang’s first ocean satellite will be launched within this year. What role will it play?Zhejiang is the province with the longest coastline and the largest number of islands in China.A few days ago, Chao News reporters learned from the Zhejiang Provincial Department of Marine Economic Development that Zhejiang’s first ocean satellite has been successfully developed and is expected to be launched in the second half of the year.Ocean satellites are a powerful tool for humans to navigate the oceans, and they are also an important infrastructure for maritime scientific research. However, Zhejiang currently has no ocean satellite in orbit. The ocean satellite planned to be launched this year is also a satellite completely manufactured in Zhejiang.At present, satellites have four main uses: remote sensing, communications, navigation, and scientific experiments. From government management to civilian applications, there are many complex problems for which solutions can be found through satellites.Last year, in response to the needs of remote sensing monitoring of water quality in the seawater system, estuaries, bays, and coastal waters of Zhejiang Province, as well as remote sensing inspection of sewage discharge into the sea, Hangzhou Dianzi University (referred to as "Hangdian") and the Second Institute of Oceanography of the Ministry of Natural Resources (referred to as " With the support of the Provincial Department of Science and Technology's "Pioneer" and "Leading Goose" research and development projects, some advantageous units in satellite research and development in Zhejiang Province, including the "Second Institute of Oceanology") and Hangzhou Institute of Science and Technology of China, jointly established the project to develop Zhejiang Province's first ocean satellite. This is A 70kg high-resolution optical small satellite can not only be used for land and sea coordination and coordinated pollution and carbon inspection in Zhejiang Province, but can also further promote the upgrading of Zhejiang’s “digital economy”.It is understood that the satellite was designed with key parameters and indicators demonstrated by the Second Institute of Oceanology. Hangzhou Electric and Zhejiang University jointly designed and manufactured the satellite platform and communication system with the Geely Group Star Intelligent Satellite Factory. The Hangzhou Higher Institute of Science and Technology of China developed the satellite payload. All work was carried out in Zhejiang Completed within the province. This ocean satellite has a design resolution of 10 meters (currently the highest among similar satellites in my country is 20 meters) and a width of 200 kilometers. Its comprehensive indicators are world-leading. Its mission uses a satellite-borne edge computing module, which is the first in the country. It has 8 channels of visible light and The spectral coverage of 2-channel shortwave infrared can meet the needs of both military and civilian use. Due to the adoption of the currently internationally popular industrialized device integration system, the cost has been significantly reduced to nearly 1/10 of the traditional satellite manufacturing model.Currently, the ocean satellite platform and payload have been developed. The expected debut time is July 2024, and the launch time is expected to be September this year.While developing the first ocean satellite, the joint working group also carried out preliminary research on the planning and related applications of the second and third ocean satellites, and carried out high-resolution infrared spectrum imaging, intelligent real-time processors, high-resolution Research on key core technologies such as remote sensing monitoring of water quality and ocean carbon flux, high-frequency low revisit interval all-day remote sensing hybrid constellation. According to the head of the joint working group, the second and third Zhejiang Ocean Satellites are expected to be delivered in 2025-2026. After the three ocean satellite constellations are networked, they can conduct remote sensing inspections of the coastal zones of my country's coastal provinces and cities with a resolution of 10 meters and once every five days, breaking the "stuck" situation of high-resolution ocean remote sensing.
Zhejiang’s first ocean satellite was successfully developed: Hangzhou University of Electronic Science and Technology took the lead and was jointly developed by Geely’s Xingkong Zhilian and other units
