On January 1, the Jilin-1 Gaofen 07 series satellite, utilizing its nighttime light imaging capability, successfully captured China's inaugural ultra-high-definition color nighttime light remote sensing image. This remarkable feat showcases the nighttime splendor of the Harbin Ice and Snow World park on New Year's Eve. The achievement of ultra-high resolution is attributed to sensor systems that integrate supplementary observation channels, enabling the acquisition of more detailed information. Consequently, the data volume generated by such satellites experiences a significant surge, multiplying several times over compared to conventional systems.
In its nighttime light imaging mode, the Gaofen 07 series satellite is capable of acquiring nighttime light push-broom images with a 15-kilometer width, characterized by exceptional spatial resolution and precise uncontrolled positioning accuracy. The satellite achieves this through a reduced-speed push-broom technique, operating under ultra-stable attitude control. This method is complemented by a long-exposure advanced-stage time delay and integration technique, which substantially enhances detection sensitivity. These advancements underscore the satellite's robust potential for a wide array of market applications.
