2025-06-06
Suzhou No.1 Satellite (Jitian Star A-03) and Jilin University No.1 Satellite (Jitian Star A-01) are the new generation of optical remote sensing experimental constellations independently developed by Jitian Xingzhou. 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, multispectral, and hyperspectral resolutions are 3m, and the width is 15km.
Non orbital one-time transit curve imaging technology is an imaging technique in which the camera of an optical remote sensing satellite actively scans the target distribution along the ground curve during one transit (i.e. one flight over the target area) while orbiting in a north-south direction. This technology is based on the innovative design concept of "moving target, fixed imaging surface", and has the ability to image curved targets at the kilometer level in one go.
Jitian Star A-03 (Suzhou No.1 satellite) was successfully launched on August 29, 2024. As of May 30, 2025, it has been in orbit for 274 days and has completed 516 non orbital imaging missions, obtaining 19153 remote sensing images with a cumulative effective shooting distance of over 210000 kilometers and a coverage area of approximately 1.9 million square kilometers. Excluding cloud cover and other conditions, it has accumulated 17812 distributable data.
Jitianxing A-01 satellite (Jilin University No.1 satellite) was successfully launched on September 24, 2024. As of May 30, 2025, it has been in orbit for 248 days and has completed 322 non orbital imaging missions, obtaining 12505 remote sensing images with a cumulative effective shooting distance of over 110000 kilometers and a coverage area of approximately 870000 square kilometers. Excluding cloud cover and other conditions, it has accumulated 12129 distributable data.
The overall situation of non orbital coverage of Jitian Double Star as of May 30, 2025 is shown in the following figure, where the red area is the coverage area of Jitian Star A-03 and the green area is the coverage area of Jitian Star A-01.
As a new remote sensing observation method, non rail transit curve imaging technology has broken through the limitations of traditional rail scanning and demonstrated excellent adaptability. With the excellent maneuverability and high-precision attitude control of satellites, the non orbital one-time transit curve imaging technology has achieved multi-dimensional imaging form innovation: it not only supports non orbital straight line push scan imaging, but also actively curves imaging along the direction of rivers, pipelines, coastlines, etc., accurately matching geographical feature characteristics. This technological feature of "targeted precision+shape plasticity" provides a new solution for complex needs such as disaster emergency response and resource investigation.
On October 31, 2024, Jitian Star A-01 successfully achieved efficient imaging of the Yellow River bend region, innovatively adopting a non orbital mode almost perpendicular to the orbital direction, and completing a single imaging coverage of 145 kilometers of the Yellow River strip. This technological breakthrough has enabled the Yellow River observation task, which originally required at least ten operations in the conventional push scan mode (with a width of 15 kilometers), to now achieve full coverage through a single imaging.
On November 4, 2024, Jitian Star A-03 non orbital imaging was conducted, spanning five provinces including Heilongjiang, Jilin, Liaoning, Shandong, and Jiangsu, with an imaging length of 1400km. Long distance non orbital imaging breaks through the limitations of traditional remote sensing satellite single track single target, and can obtain multiple target areas at once, completing tasks that previously required multiple orbit planning in one go.
On November 27, 2024, Jitian Star A-03 took non orbital curve imaging and actively scanned along the river with a length of 1360km. The non orbital one-time transit curve imaging technology achieved rapid response to complex surface features, significantly shortened the data acquisition cycle, and greatly improved the efficiency of remote sensing tasks.
On November 10 and December 2, 2024, Jitian Star A-01 successfully carried out two non orbital imaging missions, accurately covering the main urban area of Lhasa. These two missions not only validated the high-precision pointing control of Jitian Star's non orbital technology, but also effectively expanded the overall width of satellite images through image stitching.
On February 7, 2025, Jitianxing A-01 satellite conducted a push scan along the Shandong section of the Yellow River, covering a single distance of 515 kilometers. The resolution of elements such as the main river boundary, tidal wetlands, and water conservancy projects reached 3 meters, providing high-precision geographic information support for the ecological protection of the Yellow River.
On March 26, 2025, Jitian Star A-03 conducted a push scan of 735km along the Dubai coastline. This observation covered the iconic artificial buildings and natural coastal areas of Dubai, including Palm Island, Jumeirah Beach, and other areas. The resolution of the land boundary reached 3 meters, and the ecological parameters such as seawater turbidity and vegetation coverage were clearly distinguishable.
Jitian Xingzhou will soon make its debut at the 2025 Changchun International Optoelectronics Expo
