Chinese remote-sensing commercial satellite manufacturer Changguang Satellite Technology is scheduled to launch its “Jilin-1” platform 02A03 satellite in October at the Jiuquan Satellite Launch Center, Global Times writes.
The satellite is a low-cost, high-capacity, high-resolution shared remote sensing satellite developed independently by Changguang Satellite Technology, China’s first commercial remote sensing satellite company. The company has successfully launched 115 “Jilin-1” satellites in orbit, making it the world’s largest sub meter commercial remote sensing satellite constellation. It has also become an important global source of space remote sensing information, according to media reports.
The main payload of the satellite is a lightweight optical remote sensing camera, which can provide users with high-resolution remote sensing images with a resolution of 0.75 meter and a frame width of over 17 kilometers. The satellite is also equipped with a supercomputing micro-system called “Tianzhi” developed by the Institute of Software, Chinese Academy of Sciences.
The Jilin-1 satellite series has undergone four major technological breakthroughs, reducing the satellite weight from 400 kilograms to 20 kilograms and cutting costs to one-twentieth of their original level, Jilin Daily reported in September.
According to the manufacturer, by providing payload services and sharing satellite platform resources with multiple users, this satellite helps to distribute satellite launching costs.
It also includes a reflective snapshot compression hyperspectral remote sensing payload, developed by Beijing University of Posts and Telecommunications, and a GRID-11B payload that can observe gamma-ray bursts for a 24-hour on-orbit period.
