Abstract: Nighttime light data is increasingly used in areas related to human space activities. The LJ1-01 new nighttime light remote sensing satellite developed by the team of Wuhan University of China is the first professional nighttime light remote sensing satellite in the world. In order to understand the characteristic information and application potential of its data, this paper compares it with SNPP-VⅡRS nighttime light data in satellite parameters, data characteristics, data noise and application accuracy. The results show that the new nighttime light image of LJ1-01 has higher resolution and better detail features, and shows higher correlation in human space activities, reflecting the greater application potential of LJ1-01 nighttime light images. It can make a longer-term contribution to the sustainable development of mankind.

Key words: LJ1-01, nighttime light, SNPP-VIIRS, application potential
