The Jitian Double Star in orbit Test Summary Review, Image Quality Analysis Report Review, and Data Product Release Event were held in Beijing

On December 7, 2024, Suzhou Jitian Xingzhou Space Technology Co., Ltd. (hereinafter referred to as Jitian Xingzhou) organized the Jitian Double Star in orbit Test Summary Review, Image Quality Analysis Report Review, and Data Product Release Event in Beijing. At the event, it was announced that the image quality of Jitian Double Star is good, and the non orbital one-time transit curve imaging technology has been verified in orbit. It has achieved one-time imaging of curve targets over a thousand kilometers, reaching the international advanced level!

Jitian Double Star consists of Suzhou No.1 Satellite (Jitian Star A-03) and Jilin University No.1 Satellite (Jitian Star A-01). It is a new generation optical remote sensing satellite independently developed by Jitian Xingzhou and the first binary star of Jitian Xingzhou's optical remote sensing experimental constellation. The satellite is equipped with Jitian Xingzhou's innovative optical camera with core intellectual property rights of "high timeliness, high geometry, and high spectrum". It has conventional imaging and dynamic imaging capabilities, with a visible light/high spectrum ground resolution of 3m and a width of 15km. The focus is on conducting in orbit verification of "non orbital one-time transit curve imaging" and "new computational reconstruction high geometry high spectrum imaging" technologies, bridging the "last mile" of application and achieving a closed loop of related industry application business. Since its launch, Jitian Double Star has undergone careful in orbit testing and image quality adjustment and optimization. As of December 6th, it has obtained over 20000 high-resolution and high-quality remote sensing images.

More than 70 leaders, experts, and representatives from relevant user units, universities, research institutes, industry associations, investment institutions, and research and development units participated in this event. The event set up a review expert group composed of industry experts in natural resources, water conservancy, geological survey, meteorology, ocean, transportation, agriculture, special fields, as well as technical experts in scientific research institutes, colleges and universities, associations and societies. Lin Jun, a professor of Jilin University and an academician of the CAE Member, served as the team leader, and Tong Qingxi, a researcher of the Chinese Academy of Sciences Aerospace Information Innovation Institute and an academician of the CAS Member, served as the deputy team leader.

The attending leaders and experts listened to the "Summary Report of Jitian Double Star in Orbit Testing" and "Jitian Double Star Image Quality Analysis Report", and reviewed the "Jitian Double Star Data Product Atlas" and other materials. They unanimously agreed that the Jitian Double Star in orbit testing results meet the requirements of the mission book and the satellite has long-term operating conditions; Jitian Double Star is an industrialized and commercially operated satellite equipped with non orbital one-time transit curve imaging technology, with good image quality; The non rail transit curve imaging technology has been validated in orbit and has achieved one-time imaging of curve targets over a thousand kilometers, reaching the international advanced level.

Suzhou No.1 Satellite Data Product Release

Jilin University No.1 Satellite Data Product Release

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 image surface", and has the ability to image thousands of kilometers of curved targets in one go, thus achieving high time observation of typical scenarios such as the Yangtze River, Yellow River and other watersheds, oil, natural gas, power transmission pipelines, national and provincial trunk lines, highways, railways, coastal zones, borders, etc.
At the event site, remote sensing images of kilometer level curve targets obtained using non rail transit curve imaging technology were publicly released for the first time globally. Compared to the traditional push scan imaging mode, this technology provides a new solution for efficient acquisition of remote sensing images of curved targets.
