As China's first commercial remote sensing satellite company with a full industry chain that integrates satellite research & development, manufacturing, operation management, and remote sensing information services—Chang Guang Satellite Technology Co., Ltd. has achieved the phased goal of the "100 satellites in orbit" project for the Jilin-1 satellite constellation, moving from "one rocket, four satellites" to "one rocket, 41 satellites".
Currently, there are 108 satellites operating in orbit, forming the world's largest sub-meter level commercial remote sensing satellite constellation. This constellation provides precise services in 14 fields such as agriculture, forestry, water resources, environmental protection, transportation, natural resources, and urban construction. It has influenced nearly 700 upstream and downstream enterprises, bringing the distant "space civilization" from the skies to the people, injecting robust energy into the high-quality development of Jilin.
As a major agricultural and grain province in China, Jilin Province's primary task is to ensure national food security. In recent years, relying on the Jilin-1 satellite constellation, Jilin Province has vigorously developed smart agriculture and achieved remarkable results. From the high vantage point of the Jilin-1 satellite's "thousand-mile eye," the expansive and picturesque farmlands of Jilin come into view. Satellite images show that various crops are growing well, providing scientific and reliable bases for the government to understand agricultural resources.
Jia Hongguang, Secretary of the Party Committee of Chang Guang Satellite, introduced that the Jilin-1 satellite constellation features high image quality, fast response speed, and wide coverage area, capable of precise monitoring of grain planting areas at the plot level. It can also monitor the planting structures of key crops such as corn, rice, and soybeans in major regions, achieving high-precision crop yield estimates, thereby providing effective data support for promoting sustainable agricultural development and ensuring food security.
Currently, based on the massive "Jilin-1" remote sensing data, Chang Guang Satellite has constructed an intelligent agricultural product system of "one network, one map, one platform + N systems." Given the applications of the Jilin-1 satellite in the agricultural field, Chang Guang Satellite has widely carried out business throughout China, achieving satellite "precision guidance" for farming, significantly promoting agricultural transformation and upgrading, and injecting strong momentum into the modernization and development of agriculture.
Technological innovation is the lifeline of a company's sustainable development. To achieve cost reduction while ensuring product performance, the most reliable way is extensive technological innovation. As the first "unicorn" enterprise in Northeast China, Chang Guang Satellite Technology Co., Ltd. has always adhered to the "innovation-driven development" strategy, with a cumulative R&D investment of over 1.3 billion yuan. With the continuous iteration of satellite R&D technology, the company has currently built several mass production lines, including the satellite AIT pulse production line, with an annual production capacity of 200 remote sensing satellites.
Jia Hongguang, Secretary of the Party Committee of Chang Guang Satellite, introduced that after four technological advancements in satellite integrated design and manufacturing technology, the Jilin-1 satellite has decreased from the initial 400kg level to the 20kg level while ensuring that satellite performance indicators only increase. The manufacturing cost has also been reduced to one-twentieth of the original, laying a solid foundation for the rapid networking construction of "Jilin-1".
As a pioneer and leader in China's commercial aerospace field, Chang Guang Satellite Technology Co., Ltd. actively promotes industrial innovation. It not only possesses a complete industrial chain integrating satellite development, operation, and application services but also drives the collaborative development of nearly 700 upstream and downstream enterprises, initially forming an industrial agglomeration effect.
In recent years, Jilin Province has centered on the Jilin-1 satellite to create a full industry chain of satellite and aerospace information, possessing integrated capabilities from satellite manufacturing to remote sensing information services. While continuously providing high-quality aerospace information services to the country and society, it also gathers greater energy for the high-quality economic development of Jilin Province.
