Jitian Xingwen | A transit imaging data of a vertical orbit target has emerged, which is internationally advanced!
2024-12-30
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/hyperspectral resolution is 3m and the width is 15km.
The unique non orbital one-time transit curve imaging technology of Jitian Xingzhou can, based on the existing satellite attitude control system capabilities, complete vertical orbit 90 ° non orbital motion imaging of hundreds of kilometers and thousand kilometer curve non orbital motion imaging (arc, S-shape, etc.), achieve efficient observation of targets such as watersheds, pipelines, roads, borders, and coastal zones, and improve the comprehensive imaging efficiency of remote sensing satellites by an order of magnitude. Through in orbit verification, Jitian Double Star is the only satellite with non orbital one-time transit curve imaging technology that can be industrialized and operated commercially. The image quality is good and meets the design requirements; We have achieved a one-time imaging of curve targets over a thousand kilometers, reaching the international advanced level.
The Yellow River is peaceful, and the world is peaceful. "From ancient times to the present, the governance of the Yellow River has been a major event for the well-being of the people and the prosperity of the country. The Inner Mongolia section of the Yellow River, located at the top of the "Ji" shaped bay in history, has experienced multiple dangerous situations, including floods and ice floods. Satellite remote sensing images can clearly display flood precursors such as rising water levels and overflowing embankments in the Yellow River channel; Dynamically monitor the distribution of river ice, including key information such as ice density and location, to improve disaster response capabilities. For east-west targets, compared to the conventional push scan mode of multi day multiple imaging, Jitian Star can quickly and accurately obtain the target area in just a few seconds during transit, providing favorable guarantees for disaster prevention and reduction. On October 24th, the No.1 satellite of Jilin University obtained non orbital imaging data of the Inner Mongolia section of the Yellow River in China. The imaging band has an angle of nearly 90 ° with the satellite line and a length of 145km, as shown in the following figure:

On December 9th, the SuSu-1 satellite obtained non orbital imaging data during the ice flood season in Baotou section of the Yellow River in China. The imaging band formed an angle of nearly 90 ° with the satellite's downline and was 145km long, as shown in the following figure:

The the Yarlung Zangbo River basin has complex terrain, frequent geological disasters, fragile ecological environment and rich water resources. Remote sensing imaging technology can monitor the occurrence and development of geological disasters in real time; By combining water quality monitoring models, real-time monitoring and evaluation of water quality can be carried out, providing scientific basis for protecting water resources and ecological environment; Monitoring changes in the ecological environment along rivers, such as wetlands and vegetation coverage, provides important information for ecological protection; In addition, remote sensing images can quickly provide image information of disaster areas, providing critical support for emergency response and rescue work, which is of great significance for improving rescue efficiency and reducing disaster losses.
On December 19, Suzhou 1 satellite obtained the non orbiting imaging data of the the Yarlung Zangbo River from the east of Shannan City in the Xizang Autonomous Region to the southwest of Linzhi City. The angle between the imaging strip and the understellar line reached nearly 90 °, and the length was 136km, as shown in the following figure:

As the first commercial remote sensing satellite constellation equipped with non orbital one-time transit curve imaging technology, we welcome new and old users to call or write to inquire!
