Our country is accelerating the layout of hyperspectral satellites.

Since the beginning of this year, China's commercial aerospace industry has maintained a high-density launch pace, successfully completing 9 launches this month and sending various types of payloads into space. Currently, China's commercial remote sensing satellite technology capability continues to iterate, with optical, radar, and hyperspectral technologies progressing side by side. The constellation network continues to expand, with a number of key technologies leading globally. On June 15, the Long March-1 Yaogan-14 carrier rocket was launched at the Dongfang Commercial Aerospace Innovation Test Zone, successfully sending 8 satellites, including the "JiXing" high-resolution 07C04 satellite, into the designated orbit. This is the latest generation of high-resolution commercial remote sensing satellites, equipped with high-precision optical remote sensing cameras. Less than 2 hours after launch, these satellites transmitted the first clear images. In the future, these satellites will regularly monitor changes in the appearance of immovable key cultural relics nationwide and their surrounding environment, upgrading some remote areas from periodic "human patrols" every few years to high-frequency "satellite patrols" several times a day. If optical satellites represent an "increase in clarity," synthetic aperture radar satellites, known as SAR satellites, are breaking through the boundaries of observation capabilities. By actively emitting microwaves and receiving signals reflected from the ground, SAR satellites can observe the ground, see through everything in scenarios such as night and fog. In March of this year, the SAR satellites Four-Dimensional High Scene 05 and 06 were successfully launched, with resolution better than 1 meter, enabling all-weather, three-dimensional, full-scene adaptive earth observation capabilities. In addition to optical and SAR satellites, remote sensing capabilities are expanding to higher dimensions - upgrading from "seeing images" to "identifying information". In recent years, China has been accelerating the development of hyperspectral satellites, with the "Dongfang Huiyan" hyperspectral satellite set to launch 2 satellites in the second half of this year. Equipped with hyperspectral lenses, it can capture spectral information beyond visible light and achieve detailed analysis of vegetation, soil, and other information based on spectral characteristics.
