01 Technological Breakthrough: Validating the Core System and Strengthening the Network Foundation

Remote sensing satellites, through continuous narrow-band imaging, can achieve precise identification of ground features, revolutionizing fields such as mineral exploration, environmental monitoring, agricultural yield estimation, and disaster early warning. The Tanli satellite, equipped with a new multispectral camera, operates in a 525km sun-synchronous orbit (descending node local time 10:30). Its core mission is to conduct on-orbit verification of key technologies such as the fully automated onboard mission planning system and high-precision orbit extrapolation, laying the foundation for subsequent comprehensive improvement of ultra-high-precision positioning in the constellation network. This launch further consolidates CAS Xi'an Optoelectronics Technology Co., Ltd.'s leading technological position in the commercial remote sensing field.

02 Operational Upgrade: Number of Satellites in Orbit Exceeds Ten，Service capabilities have been comprehensively improved.

With the successful launch of the Tanli satellite, the number of satellites in orbit at CAS Xiguang Aerospace has jumped from single digits to double digits, marking a new milestone in the operational capabilities of the "Xiguang-1" constellation. This satellite will join the nine previously launched satellites to form a more complete satellite constellation, providing more comprehensive and accurate data services to global customers.

03 Regional Integration: Shanxi and Shaanxi Join Hands，Remote sensing empowers Shanxi's industrial transformation

Shanxi Provincial Institute of Geophysical and Chemical Exploration Co., Ltd., as a major customer of the satellite, will leverage the verification data from the Tanli satellite to promote applications in mineral exploration, mining area monitoring, ecological restoration, and agricultural and forestry management. The collaboration between the two parties centers on an integrated "space-air-ground" remote sensing database, integrating multi-source data to support the transformation needs of Shanxi's agricultural, forestry, water resources, and mining industries, creating a regional demonstration of "data-technology-industry" linkage. In the future, the two parties will embark on comprehensive cooperation to jointly explore new opportunities in the commercial aerospace field and jointly tap into new frontiers.

04 Looking to the Future: Accelerating Network Deployment and Building a Commercial Aerospace Ecosystem

Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD plans to complete the networking of 158 satellites by 2030, constructing a fusion observation system of "hyperspectral + multi-source remote sensing" to deepen applications in agriculture, forestry, and carbon sequestration. With the promotion and deepening of national policies, the commercial aerospace industry has moved from "cultivation" to "promotion," from a "strategic emerging industry" to a "new growth engine." China's commercial aerospace industry is shifting from "following" to "running alongside," injecting "Chinese wisdom" into global sustainable development. Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD will continue to promote technological innovation, work with industry chain partners to build an ecosystem, and contribute Chinese wisdom to sustainable development.

Industry Background

Currently, China's aerospace industry is developing rapidly under the impetus of national strategies, with major cities forming distinctive industrial clusters based on their own advantages. Beijing, as a traditional aerospace center, is home to numerous national-level research institutes and leading enterprises; Shanghai, with its comprehensive technology, occupies an important position in satellite manufacturing, rocket launch, and other fields; Wuhan is using commercial aerospace as a breakthrough to promote the coordinated development of the upstream and downstream of the industrial chain; and Xi'an, as an important base for China's aerospace industry, has become an aerospace science and technology hub in Northwest China, thanks to its strong satellite R&D capabilities and remote sensing data processing and application technologies.

International commercial space companies are also rapidly emerging. Companies like SpaceX and BlueOrigin are using innovative technologies such as 3D printing and reusable rockets to continuously break through the limitations of traditional spaceflight models, propelling the global space industry into a new phase of commercialization and cost reduction. Furthermore, the widespread application of emerging technologies such as big data, cloud computing, and artificial intelligence is injecting new vitality into commercial spaceflight and accelerating the intelligentization and popularization of remote sensing data services.
