Chinese space companies are expanding satellite services such as communication, navigation, and remote sensing, and at the same time pursuing better services to accelerate satellite constellations.
At the beginning of 2025, the Chainawell Wall Industry Corporation (CGWIC), which provides commercial launch and in-satellite transport services, will distribute intelligent remote sensing satellites known as IRSS-1. Is completed.
The 1 -meter resolution satellite, released on November 11, 2024, is 95 kilograms, and has a five -year design life. Used for land and forest surveys, urban planning and disaster monitoring.
According to CGWIC, if satellite distribution is successful, Oman’s remote sensing satellite application function will play an important role in improving the function function.
Wide remote sensing coverage
Chang GUANG Satellite Technology Co., Ltd. Log-oned on the LTD website can browse the satellite images taken by the company’s Jilin-1 satellite constellation.
The Jilin-1 Constellation, where the satellite group of the satellite group was first released in October 2015, is currently equipped with more than 117 satellites, and can observe any points on the earth about 40 times a day. According to Huang Jian, the head of the overseas business data application.
Huang states that the Jilin-1 Constellation can cover the whole China 24 times a year, six times a year, so that it can provide frequent updates of satellite images in every place, and this feature is the company’s overseas business. I added that it supports the enlargement.
Chang GUANG cooperates with more than 130 overseas users when providing land surveys, urban architectural surveys, agricultural and forestry services.
In response to disasters and emergencies, the company has recently provided satellite images of fire and floods in various regions in the world in response to the requests of the United Nations.
According to Xuan Ming, Chairman and General Manager of Chang GUANG, the company is planning a new constellation consisting of 200 satellites. This new constellation is 20 centimeters and can cover the entire glove once a day.
The time resolution allows you to reconsider all points on the earth within about 3 minutes in combination with the contribution of Jilin-1 constellation.
Efficient communication network
The commercialization of aerospace aerospace sector in China began when the National State Agency was encouraged by the National State Agency in 2014 that private capital would participate in the construction of a private space infrastructure of the people.
Geespace, established in 2018, is a science and technology innovation company under GEELY, a Chinese automaker. Currently, 30 satellites are operated by three orbit, so we have achieved 90 % of the world’s 90 % of 24 -hour coverage and provide satellite communication services to overseas users.
These satellites are part of the Geesatcom constellation. Low orbit communication constellations enables direct satellite connections for automatic driving, intelligent Internet connections, smartphones, and other consumer electronic products.
Geesatcom completed the first commercial development test in the Middle East in June 2024. We will cooperate with many global operators when turning on global commercial applications.
According to Geespace founder Wan Yang, Geespace provides global moderate speed satellite communication operations, satellite -based high -precision positioning services, and satellite remote sensing AI, according to the combination of GeessAtcom and its ground system. I am.
In the future, Geespace expects to access satellite application services for both Southeast Asia and Africa clients.
Spacesail, another Chinese commercial satellite constellation, will provide Brazilian satellite communication services in the remote and inadequate areas of the country since 2026, providing broadband Internet access.
Spacesail is a low -global orbital megacontel with a full frequency band, multilayer and multi -oriented design. Its commercial network was officially started on August 6, 2024.
The market for connecting smartphones directly to satellites is becoming more and more promising. “Almost every location on the earth, including the sea, desert, and remote mountainous areas where conventional communication is difficult, except for the Arctic and Antarctica, you can enjoy a stable network connection directly connected to satellites. Wang said. 。
By the end of June 2024, 546 commercial and space companies were registered in China and operated effectively, Wang Cheng, Secretary -General of the Chinese Space Foundation, was held in ZHUHAI, Guangdong Province, southern China last year. It was mentioned at the China Airlines Aviation Aerospace Exhibition (Air Show China). state.
The development of this booming of Chinese commercial satellite companies was firmly supported by a series of relevant policies.
In the period from 2015 to 2025, China aims to support and regulate both the medium and long -term development plans of private cosmic infrastructure, and to support and regulate the development of the commercial space industry.
According to Li Guoping, Chief Engineer of the China National Space Bureau (CNSA), the country maps the development plan for private cosmic infrastructure from 2026 to 2035.
