-Jilin-1- carries a new star with multiple payloads and leaves the factory. Space -carpooling- promotes one star with multiple functions

In an exciting development for the aerospace industry, Changguang Satellite Technology Co., Ltd. introduced its latest satellite, the Jilin-1 Platform 02A03, on October 9 in Changchun. This innovative platform is designed to support multiple payloads, offering valuable resources for participants in the aerospace sector.

As the pioneering commercial remote sensing satellite company in China, Changguang Satellite has achieved remarkable success with its Jilin-1 satellite constellation, which is now recognized as the world’s largest commercial remote sensing satellite constellation capable of sub-meter-level resolution. Currently, the constellation operates 115 satellites in orbit, making it a vital source of remote sensing information on a global scale.

The Jilin-1 Platform 02A03 distinguishes itself as a cost-effective, high-capacity, and high-resolution shared remote sensing satellite, developed independently by Changguang Satellite. This platform is designed to maximize efficiency while reducing satellite development costs through shared resources among users.

At the heart of the Jilin-1 Platform 02A03 is a compact optical remote sensing camera, capable of capturing high-resolution images with a remarkable 0.75-meter resolution and a swath width exceeding 17 kilometers. In addition to this primary payload, the satellite is equipped with several cutting-edge technologies, including the Tianzhi Supercomputing Micro System, a reflective snapshot compressed hyperspectral remote sensing payload, and the GRID-11B payload.

The Tianzhi Supercomputing Micro System, developed by the Institute of Software at the Chinese Academy of Sciences, aims to validate advanced capabilities such as autonomous mission planning, on-orbit intelligent data processing, and precise star sensor calculations. Meanwhile, the reflective snapshot compressed hyperspectral remote sensing payload, created by Beijing University of Posts and Telecommunications, seeks to showcase the benefits and application potential of computational spectral imaging in remote sensing. The GRID-11B payload, a collaborative effort between Tsinghua University and Star Measurement Future, enables continuous on-orbit observations of gamma-ray bursts.

Weighing in at approximately 20 kilograms, the total weight of the Jilin-1 Platform 02A03, including its payloads, is only 52 kilograms, leading to significant cost efficiencies.

The launch of the Jilin-1 Platform 02A03 is scheduled for later this month at the Jiuquan Satellite Launch Center in China, marking another milestone in the evolution of commercial remote sensing technology.
