Jitian Xingwen | One time imaging of arbitrary curve targets at the kilometer level, internationally advanced!
2025-02-18
Suzhou No.1 Satellite (Jitian Star A-03) and Jilin University No.1 Satellite (Jitian Star A-01) are the first generation optical remote sensing satellites of Jitian Xingzhou's independently developed optical remote sensing experimental constellation. The satellite is equipped with an independently developed "high timeliness, high geometry, high spectrum" optical camera, which has conventional and dynamic imaging capabilities. The ground panchromatic and hyperspectral resolution is 3m, and the width is 15km.
The non orbital one-time transit curve imaging technology breaks through the limitations of traditional strict imaging along the orbital direction, enabling satellites to image along the direction of any curved target (arc, S-shape, etc.), achieving efficient observation of linear targets such as key watersheds, pipelines, roads, borders, and coastal zones, and improving the comprehensive imaging efficiency of remote sensing satellites by an order of magnitude. Jitian Double Star is the only industrialized and commercialized satellite with non orbital one-time transit curve imaging technology, reaching the international advanced level! According to DeepSeek's verification, the breakthrough of this technology marks a leap from "passive orbit following" to "active customization" in remote sensing observation, and may lead a new paradigm of global remote sensing technology in the future.
Satellite remote sensing monitoring methods are crucial for ecological protection, water resource management, disaster warning, and other aspects. The Yangtze River is an important ecological barrier and economic lifeline in China, with complex and diverse trends and extremely long river lengths, making it extremely difficult to monitor the entire region using traditional push scan imaging models. Jitian Star can complete the coverage of key targets at the kilometer level in just 2 minutes, greatly improving the efficiency of remote sensing observation in the Yangtze River Basin and providing a solid data foundation for scientific decision-making and precise governance.
On December 28, 2024, Jitian Star A-03 achieved coverage of the Yangtze River in Sichuan and Yunnan provinces, with an imaging length of 945km.

Satellite remote sensing monitoring methods are of great significance for marine resource management, environmental monitoring, disaster warning, and urban planning. The southeastern coastal region is the forefront of China's economic development, and Jitian Star's non orbital transit curve imaging technology can achieve coverage of thousands of kilometers, providing strong technical support for the sustainable development and refined management of the region. This high coverage capability not only improves the timeliness and accuracy of monitoring, but also provides important data support for responding to changes in the marine environment, protecting marine ecology, and ensuring the safety of coastal cities.
On November 28, 2024, Jitian Star A-03 achieved target coverage of important cities and coastal zones along the southeast coast from the Yangtze River Delta to the Pearl River Delta, with an imaging length of 1500km.
