The Xiguang-1 01 satellite weighs 105 kg and has a designed lifespan of 3 years.Currently, China's 100-kilogram-class hyperspectral infrared integrated observation satellite boasts the highest spectral and geographic resolution and the most comprehensive functionality.The satellite has the capability to perform multiple imaging modes, including integrated detection and imaging, continuous strip imaging, multi-target imaging, video, staring, and high-speed data transmission. It has 14 main working modes, such as arbitrary payload combination imaging, playback at any time, and autonomous infrared target tracking. The mission modes are flexible, convenient, and reconfigurable, improving the efficiency of use.

The design and development of this satellite fully embodiesCentered on the loadThe satellite's design concept includes payloads such as a hyperspectral camera, an infrared camera, a panchromatic camera, an onboard intelligent processing unit, and an optical switch.All of them utilized a number of new technologies, new materials and new processes, and were the first in-orbit applications in China.It has reached a leading level in my country's commercial aerospace field.

in,The satellite's core payload is a domestically first-of-its-kind lightweight hyperspectral imager, employing APHIS high-performance ultra-lightweight and compact hyperspectral imaging technology.It operates in the visible-near infrared band with a spectral resolution of up to 1.4 nm, can acquire information from 300 spectral bands, has a ground resolution of 40 m@500 km, a swath width of 80 km@500 km, and 150~300 spectral channels. It has advantages such as miniaturization, large relative aperture, small spectral line curvature, and small color distortion.

Meanwhile, the satellite carriedFor the first time in the country, high-speed all-optical network switching technology has been successfully verified in orbit using optical switch payloads.It can provide important application value in high-bandwidth service data transmission, large-capacity switching and all-optical networking;For the first time in China, an infrared camera has achieved on-orbit use of innovative technologies such as a fully 3D-printed optical system and an all-aluminum calorimetric design.This fully realizes low-cost and ultra-fast manufacturing of remote sensing payloads. The panchromatic camera adopts a planar array imaging system, using a planar array scanning method to acquire visible-near-infrared spectral images of ground targets, with a ground resolution of 10m@500km and a swath width of 80km@500km.

Currently, the satellite has completed the parsing and splitting of the transmitted raw data, the stitching and registration of strip data, and the image scene segmentation and cataloging, generating L0-level products. Through relative radiometric correction, inter-band registration, MTF restoration, RFM model correction, and image fusion of the L0-level data, the first batch of hyperspectral remote sensing images has been successfully generated. These images clearly distinguish vegetation, cities, lakes, and other land features, exhibiting distinct categories, rich colors, and clear textures. Next, Zhongke Xiguang will further standardize and rapidly process multi-sensor data, providing users with stable and reliable standardized products quickly.

Today, based on mature commercial satellite development and on-orbit experience, CAS Xi'an Aerospace is deeply implementing the design concept of off-the-shelf commercial aerospace products, applying a series of new material and process innovations to satellite development and design. Compared with traditional satellites, this significantly reduces R&D costs and shortens the development cycle. In the future, CAS Xi'an Aerospace will strive to create hyperspectral commercial satellite products with stronger functionality, higher cost performance, and wider coverage, providing solid support for the continuous progress of my country's commercial aerospace industry.
