Changguang Satellite announced today that the Jilin-1 Gaofen 07 series satellite will adopt night-light imaging mode on January 1.Successfully obtained the first very high-resolution color night-time light remote sensing satellite image in China.Very high resolution in the field of remote sensing usually refers to sensor systems that obtain land, ocean, and atmospheric information by increasing observation channels.
The data volume of this type of satellite can be increased several times compared with existing systems, and the image data generation rate can reach tens of Gbps.
This image shows the night view of Harbin Ice and Snow World Park on New Year's Day.
In night light imaging mode,Gaofen 07 series satellites can acquire high spatial resolution and high uncontrolled positioning accuracy night-light push-sweep images with a width of 15km, achieving good imaging of a single street lighting area.
This imaging mode uses reduced-speed push-broom technology under ultra-stable attitude control, combined with a long-exposure advanced digital time delay integration method, to significantly improve detection sensitivity.
According to preliminary application evaluation, this technology has good market application prospects.
